Motorcycle Sunglasses – Is It For You?
Sunglasses are worn everyday by wide variety of ages and you can see sunglasses on women and men alike. What about motorcycle sunglasses? What are theit purpose?
Riding a bike wearing motorcycle sunglasses and no helmet is definitely the cool Terminator style that has made Arnold Schwarzenegger famous. Definitely dark shades look great on motorcycles, but what about real life usage? 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. Durability, quality and rigorous protection represent the criteria for the design for quality motorcycle sunglasses. Lens and frame durability is justified by the impact with road debris that often happens at high speed.
Shattering and chipping result from the contact of poor quality motorcycle sunglasses with small pebbles for instance. 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 have special testing procedures to check the resistance of motorcycle sunglasses to impact and temperature variations.
Moreover, motorcycle sunglasses include special anti-glare coating that is a form of polarization for the elimination of the contact between eye and reflected light. 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. The relevance of such features is very high given the fact that it is unacceptable to ride the bike when the road is too bright or you have to squint against the sun. From this point of view motorcycle sunglasses are important for road safety and health protection 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. You don’t really need anti-glare features on overcast days, but the presence of clouds does not exclude the action of the ultraviolets. Consequently, eye protection require the use of motorcycle sunglasses even on low brightness. Macular degenerations, cataract and lots of other eye disorders are less likely to develop if the eyewear is adequate and of good quality.
