    When you buy polarized sunglasses, you must check it's labels that if it indicated UV protection. There is no label, or it says something vague like "UV absorbing" or "blocks most UV light" , you shall not choose it, because polarization itself does not block UV light. Besides, you also need consider the polarization of the lenses. You can check the sunglasses in the shop before buying them to determine whether or not the lenses are authentically polarized. Usually, retail outlets that sell sunglasses make testers available for you.

    It is suggested for a driver to wear the polarized sunglasses. However, when buying the polarized sunglasses, there are some small tips. First of all, you should choose the suitable color. If the color is too dark, it may affect the vision. If not, the role of filtering is small. Thus, choose from the dark brown, gray or atrovirens. Secondly, you should check the appearance of the polarized sunglasses, whether it has the scratch, impurity or other things. Then, you may check whether it has the hangtag to show the role of anti UV. Next, you may observe the quality of the polarized sunglasses. Last of all, you must try it on and feel whether it is comfortable. Only after you try it can you feel whether it is suitable. All above small tips are suggested for you when buying polarized sunglasses. Hope they are useful to you.

    Polarized sunglasses are one type of sunglasses with polarized lenses. They can reduce glare caused by strong light reflected from polarizing surfaces or by polarized diffuse sky radiation. They are usually used for driving and fishing. When you choose a pair of polarized sunglasses, you need notice two factors. One is the UV protection ability. You can choose sunglasses marked with UV400, which can avoid 90% UV into your eyes. Another is the polarization filter ability. You can ask the reference data when you choose polarized sunglasses.
