Some best polarized sunglasses and night are not removed. If you do not tell that to the fashion designer, Karl Lagerfeld, no human being on earth knows what color are your eyes.
This accessory represents an icon both style and culture: what would it be without its characteristic Lolita heart-shaped pattern or the famous round glasses John Lennon?
But the truth is that, apart fashions, play a fundamental role: to protect our eyes from the sun. Something that, unlike the skin, does not seem to worry us so much. In fact, the feeling that we underestimate the damage that can cause salt deposits to our eye health rays.
That was evident in a study by The Vision Council in which three quarters of the US population claimed to be concerned about ultraviolet rays, however only 31% were taking steps to protect themselves somehow.
On the other hand, the glasses also serve as a physical barrier against the aggressions of foreign bodies and allergens, especially in spring. “In cities with pollution, you avoid debris from entering directly into the eye,” explains Joan Sanchez, optometrist Optics OP.
The glasses are not just for summer

Most sunglasses we get when hovering the first rays of summer sun. The problem is that not hibernate ultraviolet rays are present 365 days a year and act on our eyes as a “silent murderer”.
Therefore, we must not let our glasses to the beach one sunny days, but we have to use them throughout the year, as indicated Sanchez: “The fact relate sunglasses with good weather is wrong. We need to protect ourselves from ultraviolet that are always present while there is daylight, winter or summer. “
Our eyes also have memory and accumulates the damage by the sun over the years “
All this can make our eyes burn and suffer injuries. For example, forget the glasses when we go skiing can cause actinic keratoses or “snow blindness” and those who are far to the beach are at risk of pterygium, an abnormal growth of the conjunctiva on the cornea.
