- Eye Protection
Three levels of protection:
· UVA/UVB protection: UV rays of sunlight cause irreparable damage to the eyes. It is imperative that eyewear offer protection from these harmful rays. Be sure that your sunglasses have a minimum of 95% UVB protection as the UVB rays are the most harmful and a minimum of 60% UVA protection.
· Tinting: Tinted lenses reduce the brightness and help improve visibility in sunlight. It’s important to note that different color tinting affects your view of colors in a different way. Brown lenses block blue light making them a good choice for outdoor sports, whereas gray or green lenses are preferable for driving.
o What is polarization? While tinted lenses reduce brightness of color, they do not reduce the glare that occurs when sunlight is reflected off solid surfaces or water. A glare can blind your vision or severely decrease visibility and perception of depth and color. Polarized lenses are treated with a special chemical that prevents the glare from entering the lenses allowing maximum visibility and perception.
o When are polarized lenses beneficial? Actually, the answer is almost all of the time! Polarized lenses are beneficial in most outdoor activities. When fishing or boating polarized lenses avoid the glare of the water’s surface and actually allow you to see straight into the water noticing fish and dangerous underwater obstacles. Outdoor events and sports are safer and more pleasant when the view is undisturbed by annoying and often harmful glares. When driving sunlight can be reflected off windows, puddles, and rainwater causing exhaustion and strain on the eyes. Polarization effectively eliminates that stress.
o When are polarized lenses not beneficial? Polarized lenses make it difficult to read LCD screens, since the screens are treated with an anti-glare coating. That can be dangerous when relying exclusively on a GPS or flying an airplane.
