Scratch Resistant Coating:
Most lens materials with the exception of glass can be easily
scratched. A hard coating can be added to most lens surfaces to
protect against normal scratching.
UV Protection:
Ultraviolet rays can potentially harm the eyes. A treatment is
available for plastic lenses that can completely block harmful UV
light. Polycarbonate and High Index lenses have a UV Protectant
built in.
Anti Reflective Coatings:
Anti reflective or non-glare
coatings are available for most lens materials. Anti reflective or
“AR” coating is effective in reducing eye fatigue for computer users
or night driving.
