Shopping Advice On Motorcycle Sunglasses
Monday, September 14th, 2009
Sunglasses are worn everyday by wide variety of ages and you can see sunglasses on women and men alike. What are the motorcycle sunglasses? Why they are good?
Everybody remembers the cool Terminator style with dark sunglasses on, day or night. Definitely dark shades look great on motorcycles, but what about real life usage? Well, we have to be critical here and say that the Terminator-style is not relevant or practical for motor riding but rather for casual wear. 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. Glass lenses are a no-no for bike riding because of the risk to break and injure the biker. 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.
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. The vibration of light waves is an element that poses no kind of problem with other types of eyewear, but in the case of motorcycle sunglasses the shock has to be absorbed by the polarized coating. Squinting against the sun or road brightness is unacceptable for a biker. From this perspective motorcycle sunglasses are important for road safety and health protection given the eye damage that the glare may cause.
As for the ultraviolet protection in the entire light spectrum, motorcycle sunglasses should have a filer UV level of 400. This means that there should be a balanced combination of UV protection and polarization. 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 have a reduced incidence if the eyewear is right.
