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, 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. 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, the best sunglasses also reduce the light reflection or glare by the presence of an anti-polarizing coating.

Can lens color influence a classification of the best sunglasses? 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. 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. Greeninterferes with the perception of blue, red, orange and violet. 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 they have a good capacity to absorb radiations. Yellow lenses on the other hand are not useful against intense brightness but are great for foggy weather or driving at sunset. Protection and comfort, these is what the best sunglasses should provide. 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.
