Sunglasses of Poor Quality- Killer to Your Eyes

Scorching summer comes again! Many people choose to buy a pair of sunglasses both to diminish the harm that ultraviolet ray brought to our eyes and for the sake of beauty and fashion. As there are dazzling array of sunglasses such as oversized sunglasses, aviator sunglasses, etc.in sunglasses shops, and various ornament stores or even booth on the street, where the prices are more competitive and style may be more attractive, however, the quality is quite important.

Some people choose to buy sunglasses in small shops or even stand on the street because their prices are much lower, but they may have sore and swelled eyes after a long time wearing. As the rotational stand moves from time to time, once injury happens, you can hardly contact the seller for any compensation.

Two most commonly seen problems related to sunglasses of poor quality are: the uneven lens surface and the unqualified ultraviolet transmissivity. For the former, it triggers off the fatigue of your eyes, and for the latter, the unqualified transmissivity of ultraviolet ray will hide the visible light and allow the ultraviolet ray to penetrate the sunglasses, as the pupil will expand because of the dim light, thus more ultraviolet ray will be absorbed by your eyes. In a word, sunglasses of poor quality can by no means protect our eyes, but in turn they can lead to possible damage

It is recommended for consumers to buy sunglasses in qualified glasses shops, and take care of the qualification certificate, manufacturer and after sales service of the sunglasses. In the meantime, it is advised also to wear them before purchase, i.e. to feel the light shading performance outdoors, whether your eyes feel comfortable, and whether there is deformation of level and vertical objects seen through the lens. Besides, keep the shopping bills after purchase to defend personal right in case of violation of your legal rights.
