A lens treatment is a special additive that either bonds with the lens, or is built into the lens during the lens manufacturing process. Lens treatments are available as individual additions to lenses, and are also commonly bundled into single lens products for convenience and maximum benefit to your eyes.
Common Lens Coatings & Treatments:
Transitions Optical, Inc. has developed the world's most advanced photochromic lens technology—the ability of a lens to darken in the presence of invisible UV light. Transitions lenses are the #1 brand of photochromic lenses recommended by eye care professionals worldwide.
The UV rays in sunlight can be harmful to the eyes. Lenses that block 100% UV help to ward off various eye conditions and damage.
Scratches on lenses are distracting, plain and simple. And they can interfere with lens performance. Scratch-resistant treatments imbued into the lens surface toughen up the lenses making them more durable.
For fashion, comfort and clarity anti-reflective treatments are the way to go. They make the lens nearly invisible, and cut glare from headlights, computer screens and harsh lighting.
