How to Buy Satisfied and Protective Sunglasses?

For some young people, sunglasses are a symbol of cool and a fashionable icon. But in fact, it has more important sense on people’s eye health beyond fashion. As we know, there are some harmful rays from the sun, and long time exposure to them will cause eye and skin problems. Sunglasses can offer the very protection for you from these harmful rays. As for how to select a satisfied pair of sunglasses, most people just choose from outside style, but do not pay attention to their functions. The following will introduce how to buy a satisfied pair of sunglasses that can supply the protection you need.

The first point we should bear in mind is put function before fashion. It is not wise just to choose the fashionable style, but neglect its function. Instead, we should first choose the one UVA, UVB, HEV-resistant. UV and UVA are dangerous rays from the sun that can cause eye diseases or even blindness. FDA recommend people should choose the one with sticker of UV 400 or 100% UV protection. HEV rays are known as “Blue light”, which is short for High Energy Visible Light. This is very dangerous glare especially for driving people as this glare can make you not able to see things in front of you. Just imagine how dangerous it is. But if you wear HEV-resistant sunglasses, they will protect you from accidents caused by HEV glare.

Not only adults need protective sunglasses, children also need them as harmful glare has more dangerous effect on children’s eyes. More and more sunglasses companies have noticed this demand and researched a lot to satisfy children’s need. Even for infants, they can relax, and stop squirming and squinting in the sunlight with the sunglasses. But remember the toy sunglasses do not have the protection function.

A lot of people hold the idea that we only need to wear sunglasses in sunny days, but in cloudy day, there is no need to wear them. This idea is absolutely wrong. Even in cloudy days, UV rays can also pass through the cloud and send some damage to people’s eyes. This is more obvious when we take some sports on water or on snow as harmful rays can be reflected. In this kind of condition, we are suggested to wear polarized lenses which can block the light with vertically oriented polarizers. These lenses can protect you from annoying rays and painful on eyes, and even can make you less premature wrinkles around your eyes as you don’t need to squint too much.

Besides wear suitable sunglasses to protect our eyes from dangerous rays, we should also visit our eye doctor at a regular time to test if there is any change in our eyes in time. Please bear in mind a little change in our eyes may cause big problem in our later life.
