Ophthalmic Lens Coating & Equipment

Premium Ophthalmic Lenses

A number of ophthalmic lens substrates are available to fill individual needs based on cost, prescription and lifestyle. To maximize visual clarity, ophthalmic lenses are designed with several thin coating layers to provide an array of features such as ultraviolet-light blocking, anti-fog, chemical, smudge, scratch and dust protection. Adding coatings to lenses drastically improves functional performance and increases its value. The popularity of coatings continues to grow as technology advances and awareness of the valuable benefits of coatings build in the market place. Premium ophthalmic lenses combine several thin layers of different coatings during fabrication to enhance durability; each coating builds an additional layer of scratch resistance to enhance the lens during this process.
