Sunglasses are eyewear that is designed to protect the eyes from ultraviolet (UV) radiation. Sunglasses are made from different kinds of materials including polycarbonate, plastic, and glass. The UV ray is responsible for causing the sunburns, damage of the cornea and the inflammation of the eyes. Sunglasses can be worn either for recreational reasons or as protection against the sun’s harmful rays. They have been popular for many decades and today the style and fashion of sunglasses have greatly improved. Today, sunglasses are not only worn by celebrities but also by people of all walks of life.
Sunglasses are available in different styles, colors, shapes and designs. They are also available with polarized lenses, which reduce the glare of sunlight. Polarized lenses are useful in two ways. First, they reduce the glare so you can see clearly even in very low light conditions. Second, they also correct eye problems such as myopia, hypermetropia and presbyopia. Polarized lenses may also be combined with eyeglasses for double protection.
The first step in choosing sunglasses for daily wear is to determine how much daily sun exposure your eyes are exposed to. This information is easily obtained by measuring your eyes at various angles with graph paper. If your eyes are sensitive to sun exposure, then you should choose eyeglasses with stronger lenses that block out more sun. The stronger the lens, the lesser the amount of sun exposure your eyes are exposed to. But make sure that the prescription that comes along with the sunglasses you want to buy are specifically designed for daily wear only.
Sunglasses are also available in various lens tints to reduce or eliminate the glare. Low-level tinted lenses reduce the glare but produce color distortion because they filter out most of the light that reaches your eyes. High-level tinted lenses are ideal for people who need maximum sun block without having to compensate for color distortion. There are also tinted lenses available in near-infrared and UV-protected designs. These special designs are also useful in blocking some of the harmful rays of the sun, including UVA and UVB.
Once you have determined the primary function of the sunglasses, you can then narrow down your choices of sunglasses styles. For surfing, strapless sunglasses are ideal. These lenses don’t have any lens cams to allow for the tilting or rotating of the lenses. They are often made from carbon composites. However, these frames are heavy and expensive compared to normal sunglasses. Therefore, they are not used by most surfers.
A favorite among athletes is the polarized sunglasses, which contain tiny hole in them. Because these are extremely rare, they are usually made with high quality optical glass and lens. Some have rims while others are rimless. Because the polarized sunglasses reduce glare, they are favored by swimmers and divers. However, many people who do not spend much time in the water still prefer this pair of sunglasses because it reduces the reflection of light. It is ideal for people who do a lot of outdoor activities like hunting, fishing and hiking.
Another popular pair of sunglasses for health and fitness is the nonslip round trip. The lenses in this pair of ray ban eyeglasses are coated with a special lubricant that provides excellent protection against glare, water, and sand. Unlike the flat trip, the nonslip round trip contains an anti-reflective coating. As a result, it does not reflect light back towards your eyes when you are looking into the sun. Because it contains anti-reflective coatings, it also helps you see in the dark. However, people who need more than just protection against the sun may find this pair uncomfortable to wear.
If you want something to wear all day long, the wraparound style of sunglasses is perfect for you. The wraparound style is perfect for people who are always on the go. Since it has high levels of UV exposure protection, you can wear this pair anytime you feel like being outdoors without having to worry about your eyes being burned. You can enjoy a book while you’re out there or take pictures of your favorite landscape or scenery. No matter what your outdoor activity is, a wraparound lens will ensure your eyes are safe from harmful UVA.
