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. Lots of harm can be caused to the eye if low quality sunglasses are used. The pupil dilates because of the dark lenses, if there are no anti-UV protective features, then the ultraviolets and the infrareds become very dangerous for the eye. The radiations could impair sight and cause a wide range of ophthalmic dysfunctions such as affections of the crystalline or cataract.
Image distortion is one other flaw of poor quality sunglasses. 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. 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, besides UV protection, the best sunglasses also reduce the glare by the anti-polarizing coating that covers the lenses.
Can lens color influence a classification of the best sunglasses? 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. 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.
Brown lenses are suitable in warm and cold 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 are among the most advanced of items because they protect the sides of the eyes too against the impact of the ultraviolets. Consequently, the properties of the lenses and the eye protection should justify a high price, and not fanciful frames.
