Cheap Sunglasses vs. Expensive 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. What people don’t know is that cheap eyewear 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. 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. 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, 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, opinions differ here. The capacity to reduce light intensity and absorb the colors of the visible spectrum varies with the color. There are categories of wearers who cannot use very dark lenses because they would impair vision: 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. 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. 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!
