Sunglasses are worn each day by all ages and we can see sunglasses on men and women alike. Why motorcycle sunglasses? Why they are good?
Everybody remembers the cool Terminator style with dark sunglasses on, day or night. It definitely seems that motorcycles go best with dark shades, yet, we have to wonder about how practical that really is. Well, the kind of sunglasses matching the Terminator style are practical for casual wear and not for motor riding, no matter how cool they may look. Motorcycle sunglasses have to be compatible with the helmet and protect the biker at high speed traveling. Rigorous protection, quality and durability are the features to expect from really good motorcycle sunglasses. They have to be durable because of the high speed impact with road debris that often hits the biker in the face.
Even if we are talking about contact with very small pebbles, low quality motorcycle sunglasses will not resist the impact and will chip or shatter. Moreover, glass is never used for the lenses because of the possibility to break and harm the biker’s eye. Polycarbonate is the best material for motorcycle sunglasses design because of its light weight and resistance to superficial collisions. All the companies that design eyewear for motorcycle use pass their products through very rigorous testing so that the resistance to temperature variations, wind and impact with debris is assured.
Polarization is another key feature of motorcycle sunglasses. The glare as well as the bounces off from the pavement have to be solved by the anti-glare coating. A special element that receives no attention for other kinds of sunglasses is the vibration of the light waves, which could be a health risk at high speed conditions; in fact, the shock it produces has to be absorbed by the polarized lens layer. Squinting against the sun or road brightness is unacceptable for a biker. From this perspective motorcycle sunglasses play a major role for health protection and road safety given the eye damage that the glare may cause.
Last but not least, motorcycle sunglasses need maximum ultraviolet protection for the entire light spectrum. This means that polarization should combine with ultraviolet protection. Although the anti-glare feature is only useful on sunny days, the ultraviolets affect you no matter whether if the weather is fine or overcast. Consequently, eye protection require the use of motorcycle sunglasses even on low brightness. Eye disorders and the risk of getting cataract or macular degeneration are less likely to develop if the eyewear is right.
