It is not only your skin, your face and your head is in need of protection. Your eyes are just as vulnerable to damage than the rest of the body, perhaps even more. Therefore, it is necessary to keep them protected at all times, and a way to do this is to get a pair of sunglasses very good. But how do you choose? |
Before choosing sunglasses, however, you need to be aware of why it is necessary to wear sunglasses. Beyond fashion and style, sunglasses are designed for the most important reasons and practical.
Protection against the sun: Or, more specifically, protection against the sun's ultraviolet rays. Studies by the American Academy of Ophthalmology have proven that there is a direct correlation between the exposure of the eyes to ultraviolet radiation and ocular disease. Even if you can not look directly at the sun, ultraviolet light can still get to the eyes and cause more serious problems, such as macular degeneration and cataracts, among others.
Glare reduction: Can not be helped, we have to live with the glare of the sun on a daily basis, unless you lock yourself in your room during the day. What you could do, however, is to take steps to reduce the amount of light to a more comfortable level, thus reducing the strain on your eyes. Sunglasses will do it for you.
Protection against debris and other flying objects: Wind can also cause discomfort and irritation to the eyes, if left unprotected. With a pair of sunglasses, you can protect your eyes against strong winds and cold, as well as dust, snow, flying debris and other small objects that could damage your eyes.
Improving night vision: to protect your eyes from the intense light during the day give them easier to adapt to drastic changes in lighting conditions and light. Notice how you're struggling to adapt to the darkness of a room once you enter after staying in the sunshine too long. Your night vision will be greatly enhanced if you keep your eyes protected from the sun during the day.
