What You Need To Know About Shades

People, young and old alike, ought to have a pair of sunglasses, not to be fashionable, but primarily to shield their eyes from the harmful effect of UV rays. With so many kinds of sunglasses available, choosing the one that’s right for you is sometimes not the easiest of tasks.

Sunglasses differ greatly when it comes to design. Some of the more popular ones include aviator sunglasses which feature teardrop-shaped lenses and a thin metal frame, oversized sunglasses, and wayfarers that have trapezoidal lenses. Wraparounds are also quite commonplace, and they are the ones which have frames that follow the curved contour of the face, thereby providing the person wearing them additional protection from glare and gusts of wind that enter from the side. You can also find sport sunglasses which come in different tints to offer their wearer improved clarity in different lighting conditions.

There are plenty of lenses available, and they can come in different tints and coatings. There are those that are tinted which enhance visual contrast and depth perception, which are made with outdoor sports enthusiasts in mind. Brown lenses for example increase color contrast but also cause color distortion. Turquoise lenses on the other hand, are ideal for medium to high lighting conditions, and they provide good contrast without too much color distortion. Most pilots, boaters, recreational fishers, and hunters prefer orange lenses because these have contrast enhancement and improved width perception properties. You can also find polarized lenses which have filters that effectively reduce annoying, and sometimes dangerous intensity of glare, thereby improving comfort and visibility. There are instances however when wearing polarized lenses may not be advisable. For instance, it would be unsafe to wear one while you are skiing downhill since you will not be able to spot the glare coming from the ice patches which you have to steer clear of. There are also photochromatic lenses, and those that have anti-reflective and mirror coatings.

When shopping for sunglasses, UV protection should be a must-have feature. The label should read either UV 400 or 100% UV protection. As with other fashion accessories, you need to select sunglasses which suit your facial structure. Branded sunglasses offer styles and widths that will accommodate the largest and smallest of faces. Face shape is an important consideration in selecting a pair of sunglasses, but so is individuality. No matter how tedious it may seem, it is always best to try on at least five whenever you shop for a pair. That way, you will be able to find one that truly fits your personality. Lastly, get one that is not only comfortable on your face but also on your pocket. Keep in mind, shades do not have to be pricey to be good.
