Lens Coatings, Photochromics and Polarized Lenses

 
    
Anti-Reflective (AR) Coatings

AR is layers of microthin coating on each side of the lens. The last layer is a hydrophobic quartz coating making the lens scratch resistant and easier to clean.

AR Coating Benefits:

• Eliminate Glare
• Increased Light Transmission
• Less Eye Strain
• Optimum Optical Vision
• Increased Night Vision
• Clearer Cosmetic Lenses

Scratch Resistant Coating

Hard coating which protects the surface of a lens from incidental scratches.


  
Ultraviolate Coating 

UV treated lenses protect the human eyes from the damaging UVA and UVB sunrays. The cornea of the lens is vulnerable to snow blindness, pterygia, pingueculae, and photokeratitis. UV treated lenses minimize the effects of these problems.

Photochromic Changeable Lenses (See Photochromics Section)

Lenses that go from light to dark.

• Dark outside in bright light.
• Light inside and on overcast days.
• Cuts glare.
• Lightweight.
• Blocks 100% UVB rays.
• Scratch Resistant.

Polarized Lenses

Polarized lenses allow only selected light rays to reach the eyes. Polarized lenses remove glare so that the vision becomes more distinct and the surroundings are clearer.

Polarized lenses absorb 98% of the sun damaging ultraviolet rays. Polarized lenses protect the eyes against diseases and injuries such as snow blindness and pterygium. These lenses are available in many lens styles and tints.
