Kauai - shiny tortoise frame with amber lenses

PC (polycarbonate) lenses are about 10 times more impact resistant than normal plastic or glass lenses. They are lightweight and provide ultra violet (UV) protection.

Hydrophobic coating is applied to the outside of the lenses to combat visual distortion caused by rain, water spray and sweat, allowing droplets to simply bead off the lenses. The coating is called a nanoscopic surface layer which also helps repel grease, oil, dust and stains such as fingerprints. Another key benefit is that the lenses become very easy to clean.

Anti-reflective coating is also known as AR coating, and it is applied on the backside of sunglass lenses. The interest is to minimize glare and reflections bouncing off the reverse side of the lenses back into your eyes and disrupting the sharpness, contrast and precision of your vision. Because it helps prevent visual fatigue, AR coating is highly recommended for driving.
