RANDOLPH AIR FORCE BASE, Texas –
We all understand the importance of protecting your skin from the sun's harmful rays, but what about consistent sunglass use for protecting your eyes?
Prolonged exposure to the sun's ultraviolet rays without proper protection may lead to eye conditions that can ultimately result in severe visual impairment or blindness.
Wearing a wide-brimmed hat or sunglasses is a simple preventative care tool for your eyes during the hot summer months.
The self-protective mechanisms of the eye - the cornea, lens, and retina are not all sufficient enough to protect from the detrimental effects of the sun. Only protective eyewear can accomplish this.
There are two types of UV rays that can damage the eyes - UVA and UVB. Some of the age-related ocular diseases such as cataracts and macular degeneration can be worsened by unfiltered UV radiation.
A cataract is a "clouding" that develops over time in the normally clear lens inside the eye. This leads to improper focusing of light on the retina at the back of the eye which results in decreased vision. Cataracts tend to progress at a much faster rate with exposure to sunlight.
Surgery is warranted in late stages of cataract formation, however significantly lowering the pace of progression can be accomplished through simple UV protection.
Macular degeneration is the leading cause of vision loss among those over the age of 50. This condition results from changes to the macula, which is the portion of the retina that is responsible for central vision and clear, sharp details. Some of the more common symptoms of macular degeneration include a gradual loss of clarity in vision, distortions of objects, loss of clear color vision, or the appearance of a dark or "empty" area in the center of vision.
Early detection through regular comprehensive eye exams and UV protection are really important factors in management and prevention of this disease.
When seeking a good pair of sunglasses, it is very important to look for a label that states 100 percent UV protection. Do not assume that all sunglasses have this or offer both UVA and UVB protection.
A tinted coating on the lenses does not necessarily mean that there is adequate protection from UV exposure. The actual UV protective coating necessary is actually clear and not visible; therefore it is important to look for documentation or labels stating such. Most optical shops will carry sufficient protective eyewear for these purposes.
Because it takes many years of UV exposure to contribute to damaging effects on the eyes, it is important to start protecting the eyes at an early age and continue to as you age.
Remember, if you take care of your eyes, they will take care of you.
