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. 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, if there are no anti-UV protective features, then the ultraviolets and the infrareds become very dangerous for the eye. Sight impairment, crystalline dysfunctions and cataract could be among the severest consequences of the exposure to radiations.
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. Face match and comfort make other criteria for appreciating the features of the best sunglasses.
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 we select the best sunglasses by color too? 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: 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. 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.
Brown lenses are suitable in warm and cold 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 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.
