Why Polarized?
Polarized sunglass lenses block polarized light, which is concentrated light reflected in a horizontal direction causing what we know as glare. Glare is stronger than regular ambient light that’s very uncomfortable and can be very dangerous to your eyes.
All Zeal Optics sunglass lenses are polarized and eliminate 99.9% of glare, block 100% of harmful UV rays and 95% of HEV light (harmful blue light). This helps prevent long term damage to your eyes due to exposure to harmful HEV and UV light. By eliminating glare, you are also eliminating eye fatigue and sensitivity that comes with it so you can stay outside longer doing the activities you love.

Not All Polarized Sunglasses Are Created Equal!
A low-quality polarized lens can filter too much or too little light, leading to a distorted picture. Sunglasses that do not provide UV protection can actually cause more damage than going without because they shade the eye, causing the pupil to dilate and allow in more harmful UV rays.

Glare is Problematic…
What is the underlying reason we wear sunglasses? Ultimately, it’s comfort, to block that nasty glare, whether we buy for fashion, function, or protection. Glare confuses color and is problematic. In fact, 26% of daytime car crashes are attributed to glare and driving is rated as the #1 use for sunglasses. In fact, 39% of glare-related accidents occur between 6 and 9 am, during rush hour. More specifically, the 15 minutes after sunrise and before sunset are the most dangerous times for road glare. According to the American and Canadian Automobile Association, and eye care professionals all over the world, the best way to handle glare is to “invest in polarized sunglasses.”
