Eyelash curler

An eyelash curler is a hand-operated cosmetic tool that curls eyelashes. Usually only the upper eyelashes are curled.

History
There were different patents of this invention between 1923 and 1940. The first known patent for the eyelash curler was filed by Charles Stickel and William McDonell, of Rochester, New York. However, William Joseph Beldue was recognized as one of the first inventors while he was working for Kurlash Co., in Rochester. William Beldue and his Kurlash Company held patents in Canada, the United States, and the United Kingdom for the eyelash curler and improvements to it.

In the 1930s and in 1940s, at the top of the makeup fashion, these curlers were very popular and not expensive. The eyelash curler was patented April 7, 1931; the tool in that application closely resembles eyelash curlers sold now. Originally named Rodal, the brand changed the product's name to Kurlash.

Eyelash curlers are usually made of metal, and often have rubber pads where the curlers make contact with the lashes. The general design of these devices remains the same from the 1940s. Manufacturers include Shiseido and Shu Uemura.

Types
The two most common types of eyelash curlers are heated curlers and traditional eyelash curlers. Heated eyelash curlers deliver a more intense curl that lasts longer. However, a simpler step to add to an eye makeup routine includes a more traditional, unheated eyelash curler. An unheated curler that is curved for the natural shape of an individual's eye includes a plentiful enough pad to press against eyelashes. Before using, an unheated curler can be heated for a short time with a hair dryer, but not to the extent to burn the delicate skin above the eyes. Self-heating, battery-operated units are available.

Disadvantages
Among many advantages, there are some disadvantages to the eyelash curler. If not used with care, pulling on the eyelashes while curling can lead to weakening of the roots. Many people can damage their eyelashes by holding down the clamp on their lashes for increased lengths of time, leading to their lashes either being pulled out or falling out due to the stress of continuous clamping. This may result in the eyelashes becoming weak and eventually lead to shedding which can be very bad for an eye because they protect the eye from wind and dust and don't grow back quickly.

If not used carefully, eyelash curlers can lead to accidents where a user pinches the eyelid. Depending on the amount of pressure they apply, this can cause a serious injury to the eye. Similarly, when used warm, an eyelash curler, especially those made of metal, can cause serious burns to the eyelid. Also, some heated eyelash curlers require batteries to run, which will require maintenance to run in terms of replacement on time for smooth functioning.

Traditional Eyelash Curlers
Eyelash curlers were invented in the early 1900s from clamps and rubber pieces, and have been modified and popular ever since. Traditional eyelash curlers use a spring-loaded mechanism to clamp the eyelashes between two metal plates. The heat from the clamp helps to set the curl and make it last longer.

Heated Eyelash Curlers
Heated eyelash curlers are a newer type of eyelash curler that uses heat to curl the eyelashes. They are said to be gentler on the eyelashes than traditional eyelash curlers and can produce a more dramatic curl. Heated eyelash curlers typically have two temperature settings, so you can choose the setting that is right for each user and work similar to hair curlers.
