Don’t Let Vision Problems Deprive Your Right to Wear Sunglasses

Summer is approaching, and most of the people would like to wear sunglasses to protect their eyes from the strong sunlight and UV ray. But for people who have suffered from nearsightedness or astigmatism, the common sunglasses cannot meet their needs. In such occasion, there are several ways to solve this problem, such as the combination of contact lenses and common sunglasses, using photochromic eyeglasses, matching prescription sunglasses and wearing clip on sun glasses. Here I want to discuss the fourth method.

Clip on sunglasses refer to the prescription eyeglasses that are attached with plain sunglasses by clamping or with magnets. These sunglasses are inexpensive and convenient to assemble and disassemble as well as use. But they are heavy in weight and may press the nose bridge and check. More over, they will affect your beautiful appearance. So if you are a person who pays great attention to look, clip on sunglasses may not be your best choice.

As for how to choose clip on sunglasses, there are three aspects you should concern, namely the anti-UV function, the lens color and the lens quality. First, the anti-UV function of the sunglasses has nothing to do with its lens color. On the contrary, your eyes will be damaged if you choose the dark colored sunglasses clip ons that are with bad anti-UV function. Second, it is better to select grey and brown sunglasses lenses as they have the best visual clarity and the optimum anti-UV functions. Last but not the least, if there is movement of the object in front of the lens when you shake it, this means the lens has a bad optical quality. You will feel swollen in the eyes or dizzy if you wear such sunglasses.

Finally, I want to mention that don’t wear clip on sun glasses of which the color is too dark if you are a driver because the dark color will prolong the response time of the driver to the emergency by 100ms, consequently the traffic accidents will be more likely to happen.
