More about sunglasses Not for ‘the look’ only

The ‘look’ is for most people, the most important factors when it comes to selecting sunglasses. People believe that they are only nice accessories, ‘cherry on the top’. Even fashion shops have arrays of sunglasses for customers to make matches with attires that they just purchased in the shop. However, the ‘protection function’ should be on the top of the check list. If sunglasses can not block ultraviolet rays properly, they will harm our eyes in a long run. Ultraviolet rays (UV) should be absorbed by lenses. If the rays are not absorbed thoroughly, they will enter the retina and create permanent damage. A pair of bad quality sunglasses can impair your eyes without you knowing it. Thus we need to be aware of what we are buying.http://www.first-wholesale.com provides a wide range of sunglasses of high quality, fashionable at affordable prices.

How to select a good pair of sunglasses? Which colour of the glasses should you choose? Here are some tips:
- Pink colour glasses
Pink is a common colour. It can absorb 95% of ultraviolet rays and some visible lights. Actually the result is similar to normal glasses without colour. They have more placebo effect.

- Grey glasses
They can absorb 98% of UVs. Biggest advantage of grey glasses is they do not change the original colour of images and soften the lights effectively.

- Green glasses
Green is ‘the’ colour for Ray Ban sunglasses. Like grey glasses, they can absorb more than 99% of UVs. They are very protective already. However, some images can look a bit distorted in green classes.

- Brown glasses
As mentioned above, grey glasses can reach the same effect as the green sunglasses, but they can absorb more blue lights then the green glasses. As a result, the images seems sharper. We might encounter more colour difference with grey glasses.

- Yellow glasses
Yellow glasses can absorb 100% if UVs. The biggest advantage of this sort of glasses is that they filter most of the blue lights, which creates sharpest images among all the 5 colours.
