Many people choose their sunglasses for appearance's sake, and many models are fun and funky. Everyone wants their sunglasses to be a fashion accessory, but the primary concern when choosing your "shades" should be eye health. Fortunately, you don't have to spend much money to get the appropriate level of protection. You do need to look for certain features when you shop for your sunglasses.
Your eyes can handle some UV rays without being damaged, but the period of exposure should be brief. If you are going to be boating, biking, or even walking for any length of time, you need to shield your eyes from UVA and UVB rays. Never buy a pair of sunglasses that do not block 99 - 100% of these rays. Excessive exposure to UV radiation can lead to serious eye problems such as cataracts, retinal damage, and harmful tissue growth. The fibers on the surface of your eye can become unnaturally thick and uncomfortable. Wearing your sunglasses can protect your vision and help you avoid future eye surgery.
Frequently, sunglasses have dark lenses, leading people to believe that lens color matters. In fact, the color doesn't make any difference. You can choose pink, purple, or blue lenses as long as they block most if not all of UV rays. Go ahead and go dark if you like the look, but these lenses are not inherently safer. Remember, polarized lenses do not protect your eyes. They do reduce glare, but you shouldn't be fooled into feeling safer when you wear them if they don't properly screen UV rays.
You may be surprised to learn that glass lenses are the superior choice for sunglasses. Glass is an excellent UV screener on its own. If you prefer plastic lenses, don't worry. They will protect your eyes as well. However, you have to make certain that the coating stays intact. Some substances such as nail polish remover or salt water can damage this coating and leave your eyes vulnerable to harm. Just be certain to regularly check your lenses for damage.
Sunglasses can be a fun fashion accessory, but their first job is to protect your eyes. Unfortunately, your eyes may sustain damage without you being aware of it. You can adequately protect your eyes with inexpensive sunglasses. As a bonus, sunglasses can help protect your eyes from those unsightly crow's feet that often develop in the corners of your eyes as you age. Get several pairs and wear them whenever you are exposed to the sun for any length of time.
