Selecting the best sunglasses

There is nothing to expect from cheap sunglasses other than poor quality. On the other hand, reputed brand names are a guarantee of great quality standards because this is how they preserve reputation and continue tradition. Lots of harm can be caused to the eye if low quality sunglasses are used. The pupil dilates because of the dark lenses, thus the entrance gate for the infrareds and ultraviolets will be a lot higher in the absence of UV protection features. Sight impairment, crystalline dysfunctions and cataract could be among the severest consequences of the exposure to radiations.

Image distortion is one other flaw of poor quality sunglasses. The best sunglasses will not pose problems in terms of dioptric values although a doctor's opinion may be needed. Face match and comfort make other criteria for appreciating the features of the best sunglasses. If you try more pairs on, you'll see that there is a big difference between matching and not-matching glasses, as they have to fit well on the face. Then, the best sunglasses also reduce the light reflection or glare by the presence of an anti-polarizing coating.

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

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. The idea is that the best sunglasses are those that provide protection and comfort at the same time. Wraparounds have superior features too because they prevent the UV rays to affect vision on the sides of the eyes. Consequently, the properties of the lenses and the eye protection should justify a high price, and not fanciful frames.
