Sunlight may seem innocuous at first, but too much exposure can cause a lot of complications. In fact, studies suggest that sunlight is the primary source of UV radiation which damages the tissue of the eyes. Spending long hours in the sun without eye protection can increase your chances of developing eye disorders, including cataracts.Even spending two or three hours in bright sunlight obstructs the eyes' ability to adjust quickly to nighttime or indoor lighting. In addition, UV radiation can cause snow blindness, which is characterized by seeing halos around lights and experiencing a temporary loss of vision.

Your eyes naturally get exposed too much to the sun, especially if you spend long periods outdoors. If you want to protect your eyes from the blinding lights, then you may want to try wearing sunglasses. Sunglasses have dark lenses enclosed in a frame to block out sunlight or intense lights. Intense lights are as dangerous as sunlight because they can damage the retina, which results in permanent eye damage. An excellent pair of sunglasses can reduce the amount of light that enters in the eyes by as much as 97 percent.

Other than checking people out surreptitiously, sunglasses are also fashionable accessories. They significantly add to a person's oomph factor, which probably explains why sunglasses have never lost their appeal with the fashion conscious. Sunglasses also go perfectly with almost any kind of clothing, from beachwear to formal attire. If you see people with sunglasses on, they're probably flaunting their aquiline noses or hiding a hideous case of eye bags.

When choosing sunglasses, consider how it can protect you from eye hazards and how it can boost your appeal. Be meticulous in lens coating as this is responsible for protecting your eyes. Typically, the more expensive the sunglasses are, the more layers they have. Consider Portland designer sunglasses for improved durability and UV resistance.
