Hardly anyone these days ignores the importance of wearing sunglasses in sunny weather. Our eyes are very delicate and valuable organs. Not to waste your money you should make a lucrative investment in a high quality pair of sunglasses that have 100% UV resistance and wear them every time you leave your home. Everyone knows that ultraviolet rays are harmful for our skin and eyes.  What is the difference between polarized and non-polarized sunglasses? Undoubtedly, people face this question overall but according to the latest survey not everybody can answer it. Here we are to help you get to know the particulars of polarized and non-polarized sunglasses.

From the technological point of view polarized sunglasses have lenses specifically designed in order to block the horizontal glare coming from the sun. This type of lenses enables us to see distant objects which we can't view well because of the bright sunlight. First made for fishermen, now being popular among sportsmen (runners, bikers, skiers), polarized sunglasses protect our eyes from the blinding glare.

Non-polarized sunglasses also have the function of protecting our eyes from harmful UV rays and reducing bright intensity. They darken the light without taking into account its polarization (direction). General public prefer non-polarized sunglasses because they are cheaper than polarized ones since the production of polarized lenses is more expensive than the manufacture of non-polarized ones. As non-polarized sunglasses don't filter out the glare created by the sun and consequently reduce driving visibility they are not great for drivers. Looking for cheap designer glasses at Eyeweardock.com, you will be surprised to find out that even good non-polarized glasses may be a viable alternative.

If you are thinking which type of sunglasses to invest your money into pick polarized ones. Remember that you should invest quite a sum to buy quality sunglasses as for example Barton Perreira eyeglasses which offer a high protection from sun radiation and from horizontal glare. You will probably spend a bit more on them but this new pair of shades will be value for money.
