For this type of product, if there is no scientific understanding, give users an adverse impact. For example, long-term wear a certain color glasses will lead to fatigue of the human eye, wearers mistake these glasses when the sun mirror, not only will not achieve the effect of shading may also damage the human eye.We want to buy sunglasses, we must first determine the purpose of the optional shade, or in order to match the dress, from the decorative role?

Only clear these aims, combined with style and wear the actual effect of the face, I can buy the right pair of sunglasses.2, learn to read the product identification A current standard sunglasses, and do not necessarily have to attach the protective properties of the anti-UV or impact. Only when express performance products will be on these indicators for an assessment.a)   the identity of the anti-UV function UV is the sun's rays of wavelengths between 200nm ~ 380nm, including three types: UVA-band 315nm ~ 380nm, UVB, band is 280nm ~ 315nm, UVC, wavelength of 200nm ~ 280nm. The ultraviolet rays of the sun's rays reach the earth's surface (290nm ~ 2000nm) accounted for about 13%, which accounted for 97% of UVA, UVB, accounting for 3%, UVC is close to 0.

Or specify these additional protection features on the invoice, so that businesses in the event of disputes, would not be passive due to lack of evidence.c) lens color shades to meet the intended use The choice of lens color depth, depending on the place of the required activities may be, for different light sources and occasions, the color of the lens will affect the shading effect. Make the sunglasses can effectively block the Xia Jiqiang light, the color of the glasses should be sufficient depth, but the bike or car, do not choose the color is too dark lenses.Second, the identification of common sense Consumers can use the following method to simply identify the intrinsic quality of the lens:1, the degree of lens should meet the requirements of the plain glass lens, and should not affect the vision of optical flaws.
