List of oldest eyewear companies

This page lists the oldest brands and companies that have been exclusively engaged in the eyewear manufacturing industry to date, across various countries. "Eyewear" is a relatively modern term encompassing all items and accessories worn over the eyes for fashion, environmental protection, and medical purposes, including glasses (also known as 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.
