How to Select Driving Sunglasses
Thursday, December 24th, 2009
The sun is often a health and safety threat for drivers because of the hazards of poor visibility. You can get annoying headaches and acute eye weariness if you don’t wear good driving sunglasses. On the other hand, with the right driving sunglasses, you can enjoy comfort and a real vision enhancement. Even with short exposures health problems may still occur because of the response of retina to the impact of radiations. And since most of us spend a lot of time in the car, the use of quality driving sunglasses is a necessity.
The darkness of the lenses is not relevant for the anti-ultraviolet protection provided by the driving sunglasses. The efficiency of such forms of eye-wear, results from the presence of filters that block the UVA and the UVB completely and not from color alone. Melanin and amber lenses seem to be the best for driving sunglasses becauseof the capacity to absorb the UV spectrum, the enhancement of terrain visibility and the good contrast they provide. Another noteworthy issue is that of glare, which could be just as bothersome for driving. Glare is reflected light and drivers are most exposed to it because it bounces from windshields or the windows of the other cars or it shines off bumpers.
Buildings, streets and sidewalks also reflect light, and this glare can only be fought by means of polarized driving sunglasses. Reduced eyestrain and sight improvement result from the blockage of light reflection. Wraparounds are very popular sunglasses designs too because they provide a complete protection preventing the light to get to the eyes at the sides or the top. Certain sunglasses are more expensive than others, but there are many factors that influence the costs. On the average, a pair of good driving sunglasses can be bought for around 0.
Always buy driving sunglasses with polycarbonate lenses because they are lightweight. Glass lenses are still used, but they are less popular because of the weight they add to the frames. The idea is that you should try the sunglasses before buying them, and here you have one good reason why you should not shop online. Online sources are rewarding for research, and you may even find great discounts, but what if the ordered driving sunglasses don’t fit? If you have to return the sunglasses and wait for replacements, this could take a lot of time and it will ruin your joy.
