Men’s sunglasses are very important as they drive home from work, while they are at work, as well as anytime that they are in the sun. Sunglasses are a form of protective eyewear that helps protect the pupils of the eyes in very bright sunlight.
Sunglasses are used to block the glare from objects which the sun reflects off of. The reflection can damage your eyes just as much and in some cases worse than the brightness of the sun itself, other than looking straight into the sun. However, the brightness of the sun is not the only way that can damage a person’s eyes.
The sun also projects ultra violet light which can also be damaging. When a person stays in the sunlight too long these UV rays can cause burnt eyes; this term is used when the eyes become irritated and blood shot. The eyes will also become very tired and make a person feel sleepy. People also will rub their hands in their eyes. This is a very bad thing to do, as no matter how clean a person’s hands are they still have germs on them. Together with the UV rays this can cause photokeratisis, pterygia, macular degeneration, or pingueculae, any of which can lead to some temporary loss of vision, or more often blurred vision.
Ultra violet rays are classified in three categories. The UVC rays are the highest energy levels which can damage a person’s eyes. Although the Ozone layer blocks most of these rays out, there are still enough of them which still get through the atmosphere and damage your eyes. The second category is the UVB rays. These rays are the ones which help people to get a tan; these rays cause the skin to darken and can be strong enough to give some people sunburn. Researchers have discovered that over exposure to these UVB rays can cause skin cancer. They also cause wrinkling of the skin, especially around the eyes and neck areas. The last category is the UVA rays, which have a low energy, and are closer to the visible light rays. These rays are the one’s which can cause cataracts and macular degeneration. The light passes though the person’s cornea and the lens all the way to the retina of the eye.
The UV rays which are harmful to a person’s eyes depends on many factors; such as the time of day, the location a person is in, and the altitude, because the UV levels are much greater at high levels. The only way to get the best protection for your eyes is to wear Sunglasses, or anywhere that you spend a lot of time in the sun.
In the United Kingdom, sunglasses are rated differently than they are in other counties. Almost every country rates men’s Sunglasses as the ratings are set by each government. Sunglasses from the UK are rated from 0 to 7; with 0 as having no protection at all, and 7 as having 100% of full protection against the harmful rays. This is sort of misconception as many people think that just regular styles of men’s Sunglasses are giving them 100% protection, even with the polarized glasses, however, if a person’s eyes are not fully covered there is still a very high chance of receiving UV damage. Sunglasses manufacturers have realized this and have developed polarized sunglasses which wrap around the entire width of a person’s eyes. This way the eyes are protected all the way around and no sunlight can come in through the top, bottom or the sides of the sunglasses frames.
