Another reason why you should always try to buy the best sunglasses possible is image distortion. The best sunglasses will not pose problems in terms of dioptric values although a doctor’s opinion may be needed. A further criterion to appreciate the quality of the best sunglasses is by comfort and face match. 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. There are categories of wearers who cannot use very dark lenses because they would impair vision: 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. Green affects the perception of violet, blue, red and orange. For tropical locations, 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. 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!
