Tintable and High-Index Polysiloxane Coatings
For Use on Ophthalmic Lenses
Tintable and high-index polysiloxane coatings for ophthalmic lenses offer enhanced optical clarity, durability, and aesthetics. These coatings provide high abrasion resistance, and their tintability allows for customizable lens colors. The high-index properties help reduce lens thickness, improving both comfort and appearance. These index-matched coatings minimize iridescence (rainbow effects) and other undesirable optical phenomena. Ideal for prescription eyewear, they combine protection with a lightweight, stylish finish suitable for long-lasting wear.
