Since 1995, Euclid Systems Corporation has grown to become a world leader of myopia management and a leading manufacturer of advanced orthokeratology (Ortho-K) products. Euclid is the maker of the popular Emerald, which has FDA approval in the USA, as well as regulatory approvals in numerous countries throughout the globe.  In fact, Euclid was the first American company to receive government approval of Emerald in the Asian-Pacific countries, such as China and Japan. 
A passion to provide quality eye care fueled the significant growth of Euclid throughout the years. As a result, Euclid became the first U.S. Ortho-K focused company to have a wholly-owned China subsidiary. Emerald is now recognized as the safe and premium Ortho-K brand among eye care professionals around the world.

It is Euclid’s mission to be the world’s leading prescribed product for managing myopia by providing your patients with crisp, clear vision without the typical choices of glasses, daytime contact lenses, or LASIK surgery. Grow your practice while exciting your patients with a proven vision correction option that can enhance their life!
