List of oldest eyewear companies

This page provides a list of the oldest brands and companies operating only in the eyewear manufacturing business to date and in any country. "Eyewear", although a relatively modern terminology, refers to the category of all items and accessories worn over the eyes for fashion adornment, protection against the environment and medical issues, including glasses (also called eyeglasses or spectacles) and sunglasses. To be listed, a brand or company name must manufacture and sell its own eyewear products and remain operating, either in whole or in part, since inception. Generic optical stores, retailers and factories are not included in the list.
