The New Sunglasses

There is nothing to expect from cheap sunglasses other than poor quality. Low standards are not a problem with reputed brand names because their best sunglasses represent a continuation of tradition and the preservation of good reputation. What people don’t know is that cheap eyewear could cause a lot of damage to the eyes. Dark lenses cause a dilation of the pupil, if there are no anti-UV protective features, then the ultraviolets and the infrareds become very dangerous for the eye. Sight impairment, crystalline dysfunctions and cataract could be among the severest consequences of the exposure to radiations.

 

Another reason why you should always try to buy the best sunglasses possible is image distortion. This is often caused by plastic lenses that have faulty dioptric values which have not been established by medical prescription. Face match and comfort make other criteria for appreciating the features of the best sunglasses. Physiognomy plays an important role in the choice of sunglasses, and you will understand the difference between matching and not-matching glasses by trying several pairs on. Then, besides UV protection, the best sunglasses also reduce the glare by the anti-polarizing coating that covers the lenses.

 

Can we select the best sunglasses by color too? Well, opinions differ here. The capacity to reduce light intensity and absorb the colors of the visible spectrum varies with the color. Not anyone can wear dark lenses for instance because they can reduce visibility: gray is usually preferred by drivers, pilots and many other users. Green lenses have the highest efficiency in absorbing IR and UV radiation but they make certain colors hard to distinguish. Greenaffects the perception of blue, red, orange and violet. Nevertheless, when you are on vacation in some exotic location, green lenses make the best sunglasses, plus, this color has a very relaxing effect too.

 

Warm and cold environments are perfect for both cold and warm environments as well, and radiations are very well absorbed. As for yellow lenses, wear them at sunset, at dawn or on foggy weather, because they are not efficient against intense brightness. Protection and comfort, these is what the best sunglasses should provide. Wraparounds are among the most advanced of items because they protect the sides of the eyes too against the impact of the ultraviolets. And keep in mind that the price should not reflect the special design of the frames or their glamorous look but the properties of the lenses. Eye protection is the most important!
