Polarization is like noise-canceling headphones for your eyes. Glare off of horizontal surfaces like snow, water, and asphalt, decreases depth perception, reduces visual acuity, and causes eye fatigue. Our lenses filter out 99.9% of this 'visual static' for a finely tuned view of the action.
Polycarbonate is the most impact resistant lens material there is plus a natural UV filter. Into these we put energized iodine crystals positioned in vertical rows on a thin piece of film which is sandwiched between two layers of injection-molded lens material. The filter within the lens allows selected light rays to reach the eye while absorbing reflected glare or polarized light. Like a venetian blind, only vertical light waves pass through the lens, thus eliminating glare which is especially important when on the water.
To this we add layers of anti-scratch protection, on some a mirror coating and a hydrophobic coating that will repel water, grease, and grime. Water will bead up and disperse without streaking and smudges from fingerprints are wiped clean easily.
Our lenses meet ANSI Z80.3 standards for Non-prescription Sunglass and Fashion Eyewear Requirements and meets European Community (CE) Class 1 Optical Standards.
Base curve is the radius of the sphere measured from the back of the lens. Ocean Racing lenses feature styles with 6 and 8 base lens curvatures depending on the style. Models that include 6 base tend to be more flat relative to your face front while 8 base styles provide the maximum amount of wrap around your face.
