Options, Options and More Options
Today's eyeglass lens treatments make a real difference in what you see, and what you don't see. Scratches, glare, ultraviolet rays -- all are potential hazards to healthy sight that can be minimized or eliminated by a lens treatment.
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
Ultraviolet (UV) Protection:
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 secreens and harch lighting.
By reducing the intensity of the sun's glare and allowing only certain light waves to pass through, polarized lenses result in less irritation, clearer vision and better depth and color perception. While regular sunglasses or tinted lenses simply diminish the light level, polarized lenses actually reduce reflections off horizontal surfaces like roads and water.
Transitions (TM) Lenses:
These technically advanced lenses adjust as the light changes, darkening in outdoor light and quickly becoming clear indoors, so eyes are protected and comfortable in every environment.
