Poor quality, that is what comes with cheap sunglasses. 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 eye wear could cause a lot of damage to the eyes. 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. The radiations could impair sight and cause a wide range of ophthalmic dysfunctions such as affections of the crystalline or cataract.
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. 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, there are different opinions 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. The best efficiency in terms of radiation absorption features is that of green lenses, but green makes it hard to distinguish between colors. Greenaffects the perception of blue, red, orange and violet. For tropical locations, 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 they have a good capacity to absorb radiations. 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!
