Optometry

Optometry is a specialized health care profession that involves examining the eyes and related structures for defects or abnormalities. Optometrists are health care professionals who typically provide comprehensive eye care.

In the United States and Canada, optometrists are those that hold a Doctor of Optometry degree. They are trained and licensed to practice medicine for eye related conditions, in addition to providing refractive (optical) eye care. Within their scope of practice, optometrists are considered physicians and bill medical insurance(s) (example: Medicare) accordingly. In the United Kingdom, optometrists may also provide some medical care (e.g. prescribe some medications) for eye related conditions in addition to providing refractive care. The Doctor of Optometry title can also be used in the UK for those that hold the postgraduate O.D. degree.

Many optometrists participate in academic research for eye-related conditions and diseases. Optometrists receive training in refraction and monitoring of common uncomplicated eye conditions. They are not trained in any forms of surgery or laser procedures. Ophthalmologists are medical doctors and surgeons who typically hold a four-year college degree, a four-year medical degree, and at least four years of residency training after medical school.

Etymology
The term "optometry" comes from the Greek words ὄψις (opsis; "view") and μέτρον (metron; "something used to measure", "measure", "rule"). The word entered the language when the instrument for measuring vision was called an optometer, (before the terms phoropter or refractor were used). The root word opto is a shortened form derived from the Greek word ophthalmos meaning, "eye." Like most healthcare professions, the education and certification of optometrists are regulated in most countries. Optometric professionals and optometry-related organizations interact with governmental agencies, other healthcare professionals, and the community to deliver eye and vision care.

Definition of optometry and optometrist
The World Council of Optometry, World Health Organization and about 75 optometry organizations from over 40 countries have adopted the following definition, to be used to describe optometry and optometrist. "Optometry is a healthcare profession that is autonomous, educated, and regulated (licensed/registered), and optometrists are the primary healthcare practitioners of the eye and visual system who provide comprehensive eye and vision care, which includes refraction and dispensing, detection/diagnosis and management of disease in the eye, and the rehabilitation of conditions of the visual system."

History


Optometric history is tied to the development of
 * vision science (related areas of medicine, microbiology, neurology, physiology, psychology, etc.)
 * optics, optical aids
 * optical instruments, imaging techniques
 * other eye care professions

The history of optometry can be traced back to the early studies on optics and image formation by the eye. The origins of optical science (optics, as taught in a basic physics class) date back a few thousand years as evidence of the existence of lenses for decoration has been found in Greece and the Netherlands.

It is unknown when the first spectacles were made. The British scientist and historian Sir Joseph Needham, in his Science and Civilization in China, reported the earliest mention of spectacles was in Venetian guild regulations c. 1300. He suggested that the occasional claim that spectacles were invented in China may have come from a paper by German-American anthropologist Berthold Laufer. Per Needham, the paper by Laufer had many inconsistencies, and that the references in the document used by Laufer were not in the original copies but added during the Ming dynasty. Early Chinese sources mention the eyeglasses were imported.

Research by David A. Goss in the United States shows they may have originated in the late 13th century in Italy as stated in a manuscript from 1305 where a monk from Pisa named Rivalto stated "It is not yet 20 years since there was discovered the art of making eyeglasses". Spectacles were manufactured in Italy, Germany, and the Netherlands by 1300. Needham stated spectacles were first made shortly after 1286.

In 1907, Laufer stated in his history of spectacles 'the opinion that spectacles originated in India is of the greatest probability and that spectacles must have been known in India earlier than in Europe'. However, as already mentioned, Joseph Needham showed that the references Laufer cited were not in the older and best versions of the document Laufer used, leaving his claims unsupported.

In Sri Lanka, it is well-documented that during the reign of King Bhuvanekabahu the IV (AD 1346 – 1353) of the Gampola period the ancient tradition of optical lens making with a natural stone called Diyatarippu was given royal patronage. A few of the craftsmen still live and practice in the original hamlet given to the exponents of the craft by royal decree. But the date of King Bhuvanekabahu is decades after the mention of spectacles in the Venetian guild regulations and after the 1306 sermon by Dominican friar Giordano da Pisa, where da Pisa said the invention of spectacles was both recent and that he had personally met the inventor

The German word brille (eyeglasses) is derived from Sanskrit vaidurya. Etymologically, brille is derived from beryl, Latin beryllus, from Greek beryllos, from Prakrit verulia, veluriya, from Sanskrit vaidurya, of Dravidian origin from the city of Velur (modern Belur). Medieval Latin berillus was also applied to eyeglasses, hence German brille, from Middle High German berille, and French besicles (plural) spectacles, altered from old French bericle.

Benito Daza de Valdes published the first full book on opticians in 1623, where he mentioned the use and fitting of eyeglasses. In 1692, William Molyneux wrote a book on optics and lenses where he stated his ideas on myopia and problems related to close-up vision. The scientists Claudius Ptolemy and Johannes Kepler also contributed to the creation of optometry. Kepler discovered how the retina in the eye creates vision. From 1773 until around 1829, Thomas Young discovered the disability of astigmatism and it was George Biddell Airy who designed glasses to correct that problem that included sphero-cylindrical lens.

Although the term optometer appeared in the 1759 book A Treatise on the Eye: The Manner and Phenomena of Vision by Scottish physician William Porterfield, it was not until the early twentieth century in the United States and Australia that "optometry" began to be used to describe the profession. By the early twenty-first century, however, marking the distinction with dispensing opticians, it had become the internationally accepted term.

Diseases
A partial list of the common diseases optometrists diagnose/manage:
 * Cataracts
 * Dry Eye Syndrome
 * Eye tumors
 * Glaucoma
 * Diabetic retinopathy
 * Hypertensive retinopathy
 * Macular degeneration
 * Refractive errors
 * Corneal disease
 * Strabismus
 * Amblyopia
 * Uveitis

Eye examination
Following are examples of examination methods performed during an eye examination that enables diagnosis
 * Ocular tonometry to determine intraocular pressure
 * Refraction assessment
 * Retina examination
 * Slit lamp examination
 * Visual acuity
 * Color vision test
 * Visual field test
 * Dry eye test
 * Corneal Topography

Specialized tests
Optical coherence tomography (OCT) is a medical technological platform used to assess ocular structures. The information is then used by eye doctors to assess staging of pathological processes and confirm clinical diagnoses. Subsequent OCT scans are used to assess the efficacy of managing diabetic retinopathy, age-related macular degeneration, and glaucoma

Training, licensing, representation and scope of practice
Optometry is officially recognized in many jurisdictions. Most have regulations concerning education and practice. Optometrists, like many other healthcare professionals, are required to participate in ongoing continuing education courses to stay current on the latest standards of care.

Africa
In 1993 there were five countries in Africa with optometric teaching institutes: Sudan, Ghana, Nigeria, South Africa and Tanzania. Ethiopia started in 2002 at UoG. There are currently two universities (MMUST & Kaimosi Friends University) offering Bachelor of Science in Optometry and Vision Sciences in Kenya.

Sudan
Sudan's major institution for the training of optometrists is the Faculty of Optometry and Visual Sciences (FOVS), originally established in 1954 as the Institute of Optometry in Khartoum; the Institute joined with the Ministry of Higher Education in 1986 as the High Institute of Optometry, and ultimately was annexed into Alneelain University in 1997 when it was renamed to the FOVS. Currently, the FOVS has the following programs: 1) BSc optometry in 5 years with sub-specialization in either orthoptics, contact lenses, ocular photography or ocular neurology; 2) BCs in ophthalmic technology, requiring 4 years of training; and BCs in the optical dispensary, achieved in 4 years. The FOVS also offers MSc and PhD degrees in optometry. The FOVS is the only institute of its kind in Sudan and was the first institution of higher education in Optometry in the Middle East and Africa. In 2010, Alneelain University Eye Hospital was established as part of the FOVS to expand training capacity and to serve broader Sudanese community.

Ghana
The Ghana Optometric Association (GOA) regulates the practice of Optometry in Ghana. After the six-year training at any of the two universities offering the course, the O.D degree is awarded. The new optometrist must write a qualifying exam, after which the optometrist is admitted as a member of the GOA, leading to the award of the title MGOA.

Mozambique
The first optometry course in Mozambique was started in 2009 at Universidade Lurio, Nampula. The course is part of the Mozambique Eyecare Project. University of Ulster, Dublin Institute of Technology and Brien Holden Vision Institute are supporting partners. As of 2019, 61 Mozambican students had graduated with optometry degrees from UniLúrio (34 male and 27 female).

Nigeria
In Nigeria, optometry is regulated by the Optometrists and Dispensing Opticians Registration Board of Nigeria established under the Optometrists and Dispensing Opticians (Registration etc.) Act of 1989 (Cap O9 Laws of Federation of Nigeria 2004). The Board publishes from time to time lists of approved qualifications and training institutions in the federal government gazette. The Doctor of Optometry degree is awarded after a six-year training at one of the accredited universities in Imo, Edo, Kano, Kwara and Abia states.

Bangladesh
From 2010 Optometry was first introduced in Bangladesh in Institute of Community Ophthalmology Under Medicine Faculty of University of Chittagong http://icoedu.org. This institute offers a four years Bachelor of Science in optometry (B.Optom) course. Currently, there are 120 Graduated Optometrists in Bangladesh. The association which controls the quality of Optometry practice all over the country is named as 'Optometrists Association of Bangladesh' which is also a country member of World Council of Optometry(WCO).

In the year 2018, Chittagong Medical University formed and the Bsc. in Optometry course shifted to this university.

In Bangladesh, Optometrists perform primary eye care like Diagnosis and primary management of some ocular diseases, Prescribe Eye Glasses, Low vision rehabilitation, provide vision therapy, contact lens practice and all type of Orthoptic evaluations and management.

The Bangladesh Association of Optometrists-BAO is a professional organization dedicated to enhancing the skills and advancing the optometry sector in Bangladesh. With a membership of 3,000 optometrists nationwide, BAO focuses on improving eye care services and aligning with global standards to benefit the vision health of the Bangladeshi population. BAO President, Mohammad Salah Uddin and General Secretary, Md. Rajikul Hasan.

China
In China, optometric education only began in 1988 at the Wenzhou Medical University. Since that time, the discipline and the profession have emerged as a five-year, medically based program within the medical education system of China. Students in the program receive the highest level of training in Optometry and are provided with the credentials needed to assume positions of leadership in China's medical education and health care systems. In 2000, the Ministry of Health formally accepted Optometry as a subspecialty of medicine.

Hong Kong
The Optometrists Board of the Supplementary Medical Professions Council regulates the profession in Hong Kong. Optometrists are listed in separate parts of the register based on their training and ability. Registrants are subject to restrictions depending on the part they are listed in. Those who pass the examination on refraction conducted by the Board may be registered to Part III, thereby restricted to practice only work related to refraction. Those who have a Higher Certificate in Optometry or have passed the Board's optometry examination may be registered to Part II, thereby restricted in their use of diagnostic agents, but may otherwise practice freely. Part I optometrists may practice without restrictions and generally hold a bachelor's degree or a Professional Diploma.

There are around 2000 optometrists registered in Hong Kong, 1000 of which are Part I. There is one Part I optometrist to about 8000 members of the public. The Polytechnic University runs the only optometry school. It produces around 35 Part I optometrists a year.

India
In 2010, it was estimated that India needed 115,000 optometrists. In contrast, India has approximately 15,000 optometrists Bachelor of Optometry (4-year trained as per University Grant Commission Notification 5th July 2014 ) and 50,000 Diploma in Optometry (2-year trained diploma conferred By State Medical Faculty). In order to prevent blindness or visual impairment more well-trained optometrists are required in India. The definition of optometry differs considerably in different countries. India needs more optometry schools offering four-year degree courses with a syllabus similar to that in force in those countries where to practice of optometry is statutorily regulated and well established with an internationally accepted definition.

In 2013, it was reported in the Indian Journal of Ophthalmology that poor spectacle compliance amongst school children in rural Pune resulted in significant vision loss.

In 2015, it was reported that optometrists need to be more involved in providing core optometry services like binocular vision and low vision.

History of Optometry Education in India
1. In the beginning optometry education started in India during British rule in 1927, the first college was established in West Bengal with the name The Indian College of Optics and the certification was diploma in optometry.

After the independence of India then ,The Directorate General Of Health Services (DGHS) Govt of India in 1958, Introduced the first (by the Central Govt of india) Optometry education in the form of a Diploma in Optometry with the collaboration of UP State Medical Faculty Govt Of Utter Pradesh under the 2nd 5-year plan the government offered diplomas in optometry courses of two years duration conferred by State Medical Faculties which is empowered under the INDIAN MEDICAL DEGREE ACT,1916 (as per Government of India Notification Department of Education, Health and Lands No,1964 dated 16th December 1926 with effect from 15th November 1929) and first two schools of optometry were established, one at Gandhi Eye Hospital (The first Schcool of Optometry Started By Prof.(Dr) Mohan Lal), Aligarh in Uttar Pradesh, and another one at Sarojini Devi Eye Hospital, Hyderabad in Telangana,

2. Subsequently, four more schools were opened across India situated at Sitapur Eye Hospital, Sitapur in Uttar Pradesh, Chennai (formerly Madras) in Tamil Nadu, Bengalooru (formerly Bangalore) in Karnataka and Regional Institute of Ophthalmology, Thiruvananthapuram (formerly Trivandrum) in Kerala.

3. The Elite School of Optometry (ESO) was established in 1985 in Chennai (The first Schcool of Optometry/college Started By Prof.(Dr) S. Badrinath ) and was the first to offer a four-year degree course Baccularrte of Science in Optometry B.S. Optometry degree was conferred  only by the Shanker Netraliya (Elite of school of Optometry and first Principal was Dr. E. Vaithilingam) instead of any University or state Government Authority etc after that B.S. in Optometry (under off- cumpus mode)  was affiliated with Bitis Pilani University -Rajasthan and now  the same course re-affiliate with new University of State of Tamilnadu-India.

4. The School of Optometry, Bharati Vidyapeeth Deemed University, Pune (https://optometry.bharatividyapeeth.edu/) established in 1998 was the first to offer a degree four-year course and conferring Bachelor of Clinical Optometry and University offered a pathroot for diploma holders to upgrade their Diploma education to Degree of Optometry through a lateral entry program. Also, the first 2 years of the Masters of Optometry course were started here in the year 2003.

5. AIIMS -Delhi introduced a two-year Diploma in Clinical Technology -Optometry (D.C.T in Optometry) in the year 1973 and then upgraded the Diploma course to a 3year B.sc (H) in Ophthalmic Technique) in 1975 after that now the Nomenclature to Degree and course of duration changed from B, Sc(H) to Bachelor of Optometry four year duration as per UGC Notification 2014 in the year new first batch of student passed out in the year 2019

6. Now at present, there are more than fifty schools of optometry and colleges existing in India and more than 100 Universities conferring Bachelor Of Optometry (B.Optom) and Master of Optometry (M.Optom) professional degrees and Doctor of Philosophy in Optometry are awarded in India by the universities recognized by University Grants Commission (India), a statutory body responsible for the maintenance of standards of higher education in India.

Optometrists across India are encouraged to register their names in the NATIONAL COMMISSION FOR ALLIED AND HEALTHCARE PROFESSIONS ACT, 2021 which has been enforced by the Parliament of India in the year 2021 and

DOA (Delhi Optometrists Association) endorsed all updates about optometry education in India.

Malaysia
It takes four years to complete a degree in optometry. Today, optometry courses are well received by citizens. More universities and higher education studies are about to implement the courses, e.g., National Institute of Ophthalmic Sciences in Petaling Jaya whereby it is the academic arm of The Tun Hussein Onn National Eye Hospital. Other public universities that provide this course are University Kebangsaan Malaysia (UKM), Universiti Teknologi Mara (UiTM), and International Islamic University Malaysia (IIUM). There is also a private university that provides this course such as Management and Science University (MSU) and SeGi University. After completing the study in Degree in Optometry, the optometrist who practices in Malaysia must register under the Malaysian Optical Council (MOC) which is the organization under the Ministry of Health.

The Association of Malaysian Optometrist (AMO) is the only body that represents the Malaysian optometrist profession. All of the members are either local or overseas graduates in the field of Optometry.

Pakistan
Optometry is taught as a five/four-year Doctor/ Bachelors/ Bachelors with Honors course at many institutions notable among which are Department of Optometry & Vision Sciences (DOVS) FAHS, ICBS, Lahore, Pakistan Institute of Community Ophthalmology (PICO) Peshawar, Pakistan institute of Rehabilitation science Isra University campus Islamabad (PIRS), College of Ophthalmology & Allied Vision Sciences (COAVS) Lahore and Al-Shifa Institute of Ophthalmology Islamabad. After graduation, the optometrists can join a four-tiered service delivery level (Centre of Excellence, Tertiary/Teaching, District headquarter and sub-district /Tehsil headquarters). M.Phil. in Optometry is also available at select institutions such as King Edward Medical University, Lahore Department of Optometry & Vision Sciences (DOVS) FAHS, ICBS, Lahore started bridging programmes for Bachelors/ Bachelors with Honors to become Doctor of Optometry OD, Post Professional Doctor of Optometry(PP-OD), Transitional Doctor of Optometry(t-OD). Optometry is not yet a regulated field in Pakistan as there is no professional licensing board or authority responsible for issuing practise licenses to qualified optometrists. This creates difficulty for Pakistani optometrists who wish to register abroad. The University of Lahore has recently launched Doctor of optometry (OD). Imam Hussain Medical University also has launched Doctor of Optometry Program. Chairman Imam Hussain Medical University Sabir Hussain Babachan has vowed to regulate OD curriculum according to international standard.

Philippines
Optometry is regulated by the Professional Regulation Commission of the Philippines. To be eligible for licensing, each candidate must have satisfactorily completed a doctor of optometry course at an accredited institution and demonstrate good moral character with no previous record of professional misconduct. Professional organizations of optometry in the Philippines include Optometric Association of the Philippines and Integrated Philippine Association of Optometrists, Inc. (IPAO).

Saudi Arabia
In Saudi Arabia, optometrists must complete a five-year doctor of optometry degree from Qassim University and King Saud University also they must complete a one-year residency.

Singapore
Tertiary education for optometrists takes 3 years at the following institutions.

Singapore Polytechnic - Diploma in Optometry Singapore Polytechnic

Ngee Ann Polytechnic - Diploma in Optometry Ngee Ann Polytechnic

Taiwan
The education of Optometry in Taiwan commenced in 1982 at Shu-Zen College of Medicine and Management. Currently, Bcahelor degrees in Optometry can be obtained from seven universities (North to South): University of Kang Ning, Yuanpei University of Medical Technology, Asia University, Central Taiwan University of Science and Technology, Chung Shan Medical University, Dayeh University, and Chung Hwa University of Medical Technology; where as associate degrees in Optometry can be obtained from Mackay Junior College of Medicine, Nursing and Management, Hsin Sheng College of Medical Care and Management, Jen-Teh Junior College of Medicine, Nursing, and Management, and Shu-Zen College of Medicine and Management.

The Law of Optometrists was established in Taiwan in 2015, since then, Optometry students after obtaining Optometry degrees need to pass the National Optometry Examination of Taiwan to be registered as Optometrists. Currently, there are approximately 4,000 Optometrists in Taiwan (2020), and around 400 new Optometrists register annunally (2018-2020).

Thailand
Since late 1990, Thailand has set a goal to provide more than 600 optometrists to meet the minimal public demands and international standards in vision care. There are more than three university degree programs in Thailand. Each program accepts students that have completed grade 12th or the third year in high school (following US education model). These programs offer "Doctor of Optometry" degree to graduates from the program that will take six years to complete the courses. Practising optometrists will also be required to pass licensing examination (three parts examinations) that is administrated through a committee under the Ministry of Public Health.

Nowadays, the number of practising optometrists in Thailand is still less than one hundred (2015). However, it has projected that the number of practising optometrists in Thailand will greatly increase within the next ten years. In the theoretical scenario, the number of optometrists should be able to meet minimal public demands around 2030 or earlier.

Europe
Since the formation of the European Union, "there exists a strong movement, headed by the Association of European Schools and Colleges of Optometry (AESCO), to unify the profession by creating a European-wide examination for optometry" and presumably also standardized practice and education guidelines within EU countries. The first examinations of the new European Diploma in Optometry were held in 1998 and this was a landmark event for optometry in continental Europe.

France
As of July 2003, there was no regulatory framework and optometrists were sometimes trained by completing an apprenticeship at an ophthalmologists' private office.

Germany
Optometric tasks are performed by ophthalmologists and professionally trained and certified opticians.

Greece
Hellenic Ministry of Education founded the first department of Optometry at Technological Educational Institute of Patras in 2007. After protests from the department of Optics at Technological Educational Institute of Athens (the only department of Optics in Greece, until 2006), the Government changed the names of the departments to "Optics and Optometry" and included lessons in both optics and optometry. Optometrists-Opticians have to complete a 4-year undergraduate honours degree. Then the graduates can be admitted to postgraduate courses in Optometry at universities around the world.

Since 2015, a Master of Science (MSc) course in Optometry is offered by the Technological Educational Institute of Athens.

The Institute of Vision and Optics (IVO) of the University of Crete focuses on the sciences of vision and is active in the fields of research, training, technology development and provision of medical services. Professor Ioannis Pallikaris has received numerous awards and recognitions for the institute's contribution to ophthalmology. In 1989 he performed the first LASIK procedure on a human eye.

Hungary
Optometrist education takes 4 years in the medical universities in Hungary, and they will get a Bachelor of Science degree. They work in networks and retail stores and private optics, very few are located in the Health Care care system as ophthalmologists as an assistant.

Ireland
The profession of Optometry has been represented for over a century by the Association of Optometrists, Ireland [AOI]. In Ireland an optometrist must first complete a four-year degree in optometry at Dublin Institute of Technology. Following successful completion of the degree, an optometrist must then complete professional qualifying examinations to enter the register of the Opticians Board [Bord na Radharcmhaistoiri]. Optometrists must be registered with the Board to practice in the Republic of Ireland.

The A.O.I. runs a comprehensive continuing education and professional development program on behalf of Irish optometrists. The legislation governing optometry was drafted in 1956. Some feel that the legislation restricts optometrists from using their full range of skills, training and equipment for the benefit of the Irish public. The amendment to the Act in 2003 addressed one of the most significant restrictions: the use of cycloplegic drugs to examine children.

Italy
In Italy Optometry is an unregulated profession. It is taught at seven universities: Padua, Turin, Milan, Salento, Florence, Naples and Rome, as three years course (like a BSc) of "Scienze e tecnologie fisiche" as a sector of the Physics Department. Additionally, courses are available at some private institutions (as at Vinci Institute near Firenze) that offer advanced professional education for already qualified opticians (most of the Italian optometrists are also qualified opticians, i.e. "ottico abilitato"). In the last thirty years several verdicts from High Court (Cassazione) proof that optometry is a free practice and has truly education path.

Norway
In Norway, the optometric profession has been regulated as a healthcare profession since 1988. After a three-year bachelor program, one can practice basic optometry. At least one year in clinical practice qualify for a post-degree half-year sandwich course in contact lens fitting, which is regulated as a healthcare speciality. A separate regulation for the use of diagnostic drugs in optometric practice was introduced in 2004.

Russia
In Russia, optometry education has been accredited by the Federal Agency of Health and Social Development. There are only two educational institutions that teach optometry in Russia: Saint Petersburg Medical Technical College, formerly known as St. Petersburg College of Medical Electronics and Optics, and The Helmholtz Research Institute for Eye Diseases. They both belong and are regulated by the Ministry of Health. The optometry program is a four-year program. It includes one to two science foundation years, one yer focused on clinical and proficiency skills, and one year of clinical rotations in hospitals. Graduates take college/state examinations and then receive a specialist diploma. This diploma is valid for only five years and must be renewed every five years after receiving additional training at state-accredited programs.

The scope of practice for optometrists in Russia includes refraction, contact lens fitting, spectacles construction and lens fitting (dispensing), low vision aids, foreign body removal, referrals to other specialists after clinical condition diagnoses (management of diseases in the eye).

Licensing
Optometrists in the United Kingdom are regulated by the General Optical Council under the Opticians Act 1989 and distinguished from medical practitioners. Registration with the GOC is mandatory to practice optometry in the UK. Members of the College of Optometrists (incorporated by a Royal Charter granted by Her Majesty Queen Elizabeth II) may use the suffix MCOptom.

The National Health Service provides free sight tests and spectacle vouchers for children and those on very low incomes. The elderly and those with some chronic conditions like diabetes get free periodic tests. Treatment for eye conditions such as glaucoma and cataracts is free and checked for during normal eye examinations.

Training
In the United Kingdom, optometrists have to complete a 4 year undergraduate honours degree followed by a minimum of a one-year "pre-registration period", (internship), where they complete clinical practice under the supervision of a qualified and experienced practitioner. During this year the pre-registration candidate is given a number of quarterly assessments, often including temporary posting at a hospital, and on successfully passing all of these assessments, a final one-day set of examinations (details correct for candidates from 2006 onwards). Following successful completion of these assessments and having completed one year's supervised practice, the candidate is eligible to register as an optometrist with the General Optical Council (GOC) and, should they so wish, are entitled to membership of the College of Optometrists. Twelve universities offer Optometry in the UK: Anglia Ruskin, Aston, Bradford, Cardiff, City, Glasgow Caledonian, Hertfordshire, Manchester, University of Plymouth, Ulster University at Coleraine, University of Portsmouth and University of the West of England.

In 2008 the UK moved forward to offer the Doctor of Optometry postgraduate program. This became available at the Institute of Optometry in London in partnership with London South Bank University. The Doctor of Optometry postgraduate degree is also offered at one other UK institution.Aston University

Scope of Practice
In 1990, a survey of the opinions of British medical practitioners regarding the services provided by British optometrists was carried out by Agarwal at City, University of London. A majority of respondents were in favour of optometrists extending their professional role by treating external eye conditions and prescribing broad-spectrum topical antibiotics through additional training and certification.

Since 2009, optometrists in the UK have been able to undertake additional postgraduate training and qualifications that allow them to prescribe medications to treat and manage eye conditions. There are currently three registerable specialities:
 * Additional supply speciality - to write orders for, and supply in an emergency, a range of drugs in addition to those ordered or supplied by a normal optometrist.
 * Supplementary prescribing speciality -  to manage a patient's clinical condition and prescribe medicines according to a clinical management plan set up in conjunction with an independent prescriber, such as a GP or ophthalmologist or qualified optometrist.
 * Independent prescribing specialty - to take responsibility for the clinical assessment of a patient, establish a diagnosis and determine the clinical management required, including prescribing where necessary.

Optometrists in the United Kingdom are able to diagnose and manage most ocular diseases, and may also undertake further training to perform certain surgical procedures.

Training
In Canada, Doctors of Optometry typically complete four years of undergraduate studies followed by four to five years of optometry studies, accredited by the Accreditation Council on Optometric Education. There are two such schools of optometry located in Canada — the University of Waterloo and the Université de Montreal. Canada also recognizes degrees from the twenty US schools.

Licensing
In Canada, Doctors of Optometry must write national written and practical board exams. Additionally, optometrists are required to become licensed in the province in which they wish to practice. Regulation of professions is within provincial jurisdiction. Therefore, regulation of optometry is unique to individual provinces and territories. In Ontario, optometrists are licensed by the College of Optometrists of Ontario.

Representation
In Canada, the profession is represented by the Canadian Association of Optometrists. In the province of Ontario, the Ontario Association of Optometrists is the designated representative of optometrists to the provincial government.

Scope of Practice
Optometrists in Canada are trained and licensed to be primary eye care providers. They provide optical and medical eye care. They are able to diagnose and treat most eye diseases and can prescribe both topical and oral medications. They can also undertake further qualifications in order to perform some surgical procedures.

United States
Optometrists or Optometry Doctors usually function as primary eye care providers - they have a degree in eye care. They provide comprehensive optical and medical eye care, but usually not surgery. They are trained and licensed to practice medicine for eye related conditions - prescribe topical medications (prescription eye drops), oral medications as well as administer diagnostic agents. In some states, optometrists may also be licensed to perform certain types of eye surgery.

Scope of practice
Optometrists provide optical and medical eye care. They prescribe corrective lenses to aid refractive errors (e.g. myopia, hyperopia, presbyopia, astigmatism, double vision). They manage vision development in children including amblyopia diagnosis/treatment. Some perform vision therapy. They are trained to diagnose and manage any eye disease and their associations with systemic health. Optometrists are trained and licensed to practice medicine for eye-related conditions (including bacterial/viral infections, inflammation, glaucoma, macular degeneration, and diabetic retinopathy). They can prescribe all topical medications (eye drops) and most oral medications (taken by mouth), including scheduled controlled substances. They may also remove ocular foreign bodies and order blood panels or imaging studies such as CT or MRI. Optometrists do not perform invasive surgery, however In Oklahoma and Louisiana, Optometrists may perform superficial surgeries within the anterior segment of the eye. Legislation permits Optometrists in Oklahoma and Kentucky to perform certain laser procedures.

Within their scope of practice optometrists are considered physicians and bill medical insurance plans accordingly.

Optometrists in the United States are regulated by state boards, which vary from state to state.

The Association of Regulatory Boards of Optometry (ARBO) assists these state board licensing agencies in regulating the practice of optometry.

Licensing
Optometrists must complete all course work and graduate from an accredited College of Optometry. This includes passage of all parts of the national board examinations as well as local jurisprudence examinations, which vary by state.

Education and Training
Optometrists typically complete four years of undergraduate studies followed by four years of Optometry school. Some complete a 5th year of training. Their program is highly specific to the eyes and related structures. Optometrists receive their medical eye training while enrolled in Optometry school and during internships. Training may take place in colleges of Optometry, hospitals, clinics and private practices. In many instances Optometry students and Ophthalmology residents will co-manage medical cases. Instructors may be Optometrists, professors or physicians. The program includes extensive classroom and clinical training in geometric, physical, physiological and ophthalmic optics, specialty contact lens evaluation, general anatomy, ocular anatomy, ocular disease, pharmacology, ocular pharmacology, neuroanatomy and neurophysiology of the visual system, pediatric visual development, gerontology, binocular vision, color vision, form, space, movement and vision perception, systemic disease, histology, microbiology, sensory and perceptual psychology, biochemistry, statistics and epidemiology.

Optometrists are required to obtain continuing education credit hours to maintain licensure - number of hours varies by state.

Optometrists prescribing schedule controlled substances are required to renew their DEA license every few years.

Australia currently has six recognized courses in optometry, and one course seeking to obtain accreditation with the Optometry council of Australia and New Zealand:
 * Bachelor of Vision Science and Master of Optometry (BVisSci MOptom), Deakin University
 * Bachelor of Medical Science (Vision Science) and Master of Optometry, Flinders University
 * Bachelor of Vision Science and Master of Clinical Optometry (BVisSc MClinOptom), University of New South Wales
 * Bachelor of Vision Science and Master of Optometry, Queensland University of Technology
 * Bachelor of Vision Science and Master of Optometry, University of Canberra
 * Doctor of Optometry, Melbourne University (post-graduate)
 * Doctor of Optometry, University of Western Australia (post-graduate)

To support these courses the Australian College of Optometry provides clinical placements to undergraduate students from Australian Universities and abroad.

in 2016, almost 5000 optometrists in general practice were licensed with their regulatory body, the Optometry Board of Australia. Of these, approximately 2300 were registered with the scheduled medicines endorsement, which enables them to prescribe some medicines for the treatment of conditions of the eye. The Optometrists Association of Australia works to protect the interests of optometrists in Australia.

New Zealand
New Zealand currently has one recognised course in optometry:
 * Bachelor of Optometry (BOptom), The University of Auckland

In July 2014, the Medicines Amendment Act 2013 and Misuse of Drugs Amendment Regulations 2014 came into effect. Among other things, the changes to the Act name optometrists as authorised prescribers. This change enables optometrists with a therapeutic pharmaceutical agent (TPA) endorsement to prescribe all medicines appropriate to their scope of practice, rather than limiting them to a list of medicines specified in the regulation; this recognises the safe and appropriate prescribing practice of optometrists over the previous nine years.

Brazil
The CBOO (Brazilian Council of Optics and Optometry), which is affiliated to the WCO (World Council of Optometry), represents Brazilian optometrists. In conjunction with organizations representative weight of Brazilian companies, including the National Commerce Confederation for goods, services and tourism (CNC), through the CBÓptica/CNC, its defence arm of the optometric and optical industry, are defending the right of free and independent practice of optometrists, even if it is against the interests of ophthalmologists.

The Federal Supreme Court (STF), the Brazilian Court of Justice and the Superior Court of Justice (STJ), another important National Court, ruled several processes granting inquestionable victories to ophthalmologists.

In Brazilian law, however, there is an explicit recommendation that the one prescribing corrective lenses are prohibited to sell them. This restricting rule to the ophthalmologists has to keep the optic shops away from Hospitals and Eye Care Clinics since 1930, and it has to be reviewed before any further regulation for the optometrists.

Colombia
In Colombia, optometry education has been accredited by the Ministry of Health. The last official revision to the laws regarding healthcare standards in the country was issued in 1992 through the Law 30. Currently there are eight official universities that are entitled by ICFES to grant the optometrist certification. The first optometrists arrived in the country from North America and Europe c. 1914. These professionals specialized in optics and refraction. In 1933, under Decrees 449 and 1291, the Colombian Government officially set the rules for the formation of professionals in the field of optometry. In 1966 La Salle University opened its first Faculty of Optometry after a recommendation from a group of professionals. At present optometrists are encouraged to keep up with new technologies through congresses and scholarships granted by the government or the private sector (such as Bausch & Lomb).
