For many people, sunglasses are handy for protection against damaging rays. They are an inexpensive way to treat your eyes well and to prevent them from undesirable exposure. You should know that injuries from ultraviolet (UV) light can be prevented by wearing sunglasses that block UV rays and by wearing broad-brimmed hats. One advantage of sunglasses over hats resides in the fact that hats do not protect your peripheral vision; while sunglasses, and especially “wrap-around” models, do. Eyes can be injured from sun glare while boating, sunbathing and especially skiing, among other times. Eye protection is helpful while you are under tanning lamps or using tanning booths. Laser pointers have not been shown to cause eye injury.
One of the nicest things about sunglasses is that they are so easy to find, and being sold online as well as at local shops, prices are competitive, and selections are vast. Sunglasses that can be purchased without a prescription come in hundreds of models with varying shapes, materials and colors. If you’re thinking about picking up a pair of sunglasses, you’ll want to be sure to take a decent amount of time in your picking, so as to assure that you end up with something that you’ll really like. Vendors usually make this easy by offering attractive displays and mirrors, so that you can see which shades suit you and which do not.
A must-have feature for all sunglasses is complete (100 percent) protection against the potentially damaging effects of the sun's ultraviolet-A and ultraviolet-B rays. When you’re buying your sunglasses, you’ll be able to find a seal of approval (usually a sticker), which states that the lenses are “UV Safe”. Knock-offs will talk around this norm, so it’s a good idea to be sure of what you’re buying.
For some people, sunglasses with polarized lenses are often an attractive feature. These reduce glare from snow, water, highways and other reflective surfaces, so, in this way, enhancing the comfort and safety of your eyes during all kinds of activities. Another feature that is notable, if you’re thinking about picking up a pair of shades, is impact resistance. This usually refers to a special kind of plastic that keeps the frames and lenses from breaking easily upon a sudden fall or the like. If you’re an active person, or if you’re thinking about buying sunglasses for a child, this feature is highly recommended. A more current and increasingly popular feature in sunglasses is photocromicity, which refers to lenses that brighten or darken in response to the intensity of sunlight. These are great for people are constantly going on the move, changing from indoors to outdoors frequently. Finally, water-sheeting is for some, the very reason that they wear sunglasses. These have lenses that help preserve visual acuity when water (from the rain, the sea, waterfalls, etc.) strikes the lens. Comparable to the car’s windshield wipers, this feature is essential for those who are active and outside in inclement conditions.
Sunglasses are also one of the advantages to wearing contact lenses. For many contact-wearers, sunglasses are among the most important reasons for making the switch from traditional glasses. For those who still wear traditional glasses, “clip-on shades” are available in a number of styles. Sunglasses can also be prescription, for those who don’t wish to wear contact lenses or clip on shades, yet still want to wear sunglasses. As you can see, there are many things to consider when thinking about buying sunglasses and protecting your eyes.
