SLICK

Anti-Scratch - Coating protects lenses from minor scratches (like cleaning lenses with your shirt or laying glasses front side down). 

Anti-Glare -  Lens coating increases visual clarity  by allowing more light to pass through the lens while eliminating glare in all light settings. Most effective for night-time driving. Enhances your appearance by removing harsh reflections (great for photos!)

UV-400 Filter - Filters UV light rays. Works like sunscreen (but for your eyes)

Photochromatic Lenses - are UV activated. Turn dark outdoors and clear indoors. May not darken to full potential in a car due to UV blocking windshields.

CamoLens Edge -  coating conceals edge thickness in high prescriptions by painting edge of lenses the same color as your frame. Maximizes the power of Anti-Glare, Photochromatic, & CompuSpecs lenses.

Blue Light Blocker - Block lenses reflect and filter the blue light emitted in
artificial light. When light hits these lenses it displays a blue
sheen on the exterior and a yellow one on the interior
protecting your eyes from this harmful exposure of blue light.
