Selecting the Perfect Sunglass Lens for you: Guidelines for Shopping Wholesale Sunglasses

Buying a pair of sunglass is not an easy task. One hardly ever bothers to think of the different features of a sunglass. But there are things you should be careful about. Even when you are going for wholesale fashion sunglasses, you should take note of the lens material. There are different kinds available in the market. For instance CR-39 is made from hard resin and adopts the qualities of plastic. Polycarbonate is known to be synthetic plastic material which is not only lightweight, but also is extremely strong. These lenses are impact-resistant. Glass lenses are more scratch-resistant. 

If you buy glass or polycarbonate lenses, you will find less waves or blemishes. Moreover they have an even distribution of colors through the lenses. You can hold the sunglass against a tiled floor. You can cover one eye and look at the lines by moving the sunglass from the left hand side to the right hand side. One can repeat this action from up and down. If the lines appear to be straight, and you do not see waves or wiggle, you can be assured that the wholesale sunglasses have good lenses. The tint or the darkness of the sunglass is also important. If you are involved in outdoor activities like snow skiing or mountain climbing, you will need darker shades than usual. If you are going to the beach, you will need shades which will block 90% of the light. The sunglass should be capable of blocking at least 60% of the light. Otherwise it is of no use at all. So be discerning and select the right quality of sunglass lenses.
