Here is some interesting food for thought. I am very particular about my lense colors and I tend to stay with the lighter ones, blue and yellow shades. Personally I often wonder about why so many choose grey when they don’t work well for me in any condition. Here is an idea that may shed some light on the subject. Get it, “light”, ha ha, enjoy – Chilly
ADS Sports Eyewear tested gray and copper sunglass lenses to determine which color was better for motorcyclists. Results showed that the rider’s eye color was an important component in making this determination.
The company’s sales show that more than 80 percent of riders wear gray lenses and black frames. In this experiment, each participant rode through the same environment with each lens color. Their goal was to determine if either lens color helped the rider evaluate road textures or recognize subtle hazards. Prescription sunglasses were included in the evaluation, but did not appear to have any impact on the final results.
Early in the testing, researchers discovered that eye color was an important component in determining which lens colors were most comfortable, and which lenses provide the best contrast for different riders.
Medically it could be explained by the fact that lighter-colored eyes like light blue, green or hazel are more transparent and therefore more inclined to be sensitive to bright light. Contrast lenses will make the world seem brighter. This is true even when a contrast lens like a 12 percent copper or brown lens is compared to a 12 percent gray lens. Both lenses let in the same 12 percent of light, but the contrast lens will feel much brighter. This perceived brightness is neither needed or welcome for riders who are light-sensitive.
Based on this information, riders were divided into two groups based on eye color. This is how the final results were summarized:
Lighter-colored eyes: About 85 percent of riders with blue, green or hazel eyes were vastly more comfortable wearing a gray polarized lens. A couple riders with very light-colored eyes returned the glasses with copper lenses to the testers within seconds. Their reaction to trying on a copper lens was something like, “WHOA . . .way too bright”.
Darker-colored eyes: Almost every one of the brown-eyed participants stated that they had better depth perception and could see more detail when wearing a copper or brown lens as compared to a gray lens. For most of these riders, the additional contrast was considered safer and more comfortable. Even though riders in this group universally thought the contrast lenses provided better vision, some riders still preferred the true color of a gray lens.
Testing for polarization started with a longstanding belief that polarization could make it more difficult to recognize a puddle in the road because polarization will eliminate the glare from the water. This belief is common among many old-school riders, but the testers were unable to create any situation where the theory was valid. Glare made it difficult to see anything around the water. Polarization allowed the rider to see what was in the puddle and recognize the difference between a puddle and a pothole.
The general consensus was that if a rider needed glare to tell the difference between pavement and water, they were a good candidate for prescription motorcycle glasses, researchers found.
