Omit the Glare: Purifier Polarized Sunglasses

Last weekend as I was driving to Evansville to visit a friend of mine, I realized how awesome Purifier polarized sunglasses are and would have been during my drive. My drive from Indianapolis to Evansville was about 3 and-a-half hours and when I left around 5:00PM the sun was beginning to set, making the glare on my car and the roads absolutely miserable! Why all the glare?  According to howstuffworks.com writer Jeff Tyson in “How Sunglasses Work,” most of the glares that cause us to wear sunglasses come from flat, horizontal surfaces, such as water or a road.

When light strikes the surface, the reflected light waves are polarized, restricted to one direction, in order to fit the angle of the surface. So US-41 for example, a flat highway, produces a lot of polarized light that blinds me as I drive wearing my (not glare blocking) un-polarized sunglasses.  Purifier polarized lenses in sunglasses are made so that only vertically polarized light can enter thus eliminating any glare-they are the only sunglass lens to do this.  When driving wearing Purifier polarized sunglasses helps to increase reaction time by 40% compared to just wearing sunglasses that increase reaction time by 20%-they make a difference.

howstuffworks.com explains that many sunglasses advertised as being polarized to block glare actually are not.  Want to see if your sunglasses are polarized?  There’s a simple test you can perform. Find a reflective surface and hold the glasses so that you are viewing the surface through one of the lenses. When you slowly rotate the glasses to a 90-degree angle, you can see if the reflective glare diminishes or increases. You will see the glare slowly dwindle if the sunglasses are polarized.  Besides reducing glare, Purifier polarized sunglasses help shield the eyes from harmful UV-rays on sunny days and not so sunny days. Next time I’m on the road, I’ll be sure to pack Purifier polarized sunglasses to omit the glare.
