To Polarize or Not Polarize? The Great Sunglass Question...
Updated: Aug 7, 2018
If you’re an outdoor enthusiast, then you're well aware of the benefits of polarized sunglasses.
For those new to polarized lenses, these lenses are great at cutting out the glare from water, snow, and any reflections while driving.
When light is reflected from flat surfaces, it scatters in all directions (see the photo), causing glare and reduced visibility. This can be very dangerous especially while driving.
Polarized lenses have a filter built in that cuts the glare and brings the light to a pin-point focus. As a result, visibility is enhanced, less eye stain is noticed and visual comfort is improved.
However, polarized sunglasses are not recommended for every situation. Commercial airplane pilots cannot wear polarized lenses because it interferes with the plane's control panel; digital monitors will appear "blacked out". This "blacked out" effect will also be seen on GPS systems and cell phone screens.
For majority of sports and outdoor leisure activities, polarized sunglasses offer many advantages. Ask your eye care professional about combining backside anti-reflective coating with a gradient or mirror tint to maximize both your eye health and style.
