What is the difference between polarized sunglasses and uv protection sunglasses?

Question

Which is better for driving on a sunny day?

Answer 1

Polarized are better. Polarized lenses actually bend the light away from your eyes. High glare activities, like boating and skiing, benefit greatly from polarized lenses.

Almost all glasses are 100% UV protection, that is just a chemical coating sprayed on.

Polarized provides better protection and increases visibility.

Answer 2

A pair of sunglasses seems so simple -- it's two pieces of tinted glass or plastic in some sort of plastic or metal frame. How much more straightforward can something get? It turns out that there are many different things you can do with two pieces of glass, and these things can have a big effect on you when you use the lenses. As you will see in this article, there really is a difference between the various sunglasses you'll find out there.
There are four things that a good pair of sunglasses should do for you:

Sunglasses provide protection from ultraviolet rays in sunlight. Ultraviolet (UV) light damages the cornea and the retina. Good sunglasses can eliminate UV rays completely.

Sunglasses provide protection from intense light. When the eye receives too much light, it naturally closes the iris. Once it has closed the iris as far as it can, the next step is squinting. If there is still too much light, as there can be when sunlight is reflecting off of snow, the result is damage to the retina. Good sunglasses can block light entering the eyes by as much as 97 percent to avoid damage.

Sunglasses provide protection from glare. Certain surfaces, such as water, can reflect a great deal of light, and the bright spots can be distracting or can hide objects. Good sunglasses can completely eliminate this kind of glare using polarization (we'll discuss polarization later).

Sunglasses eliminate specific frequencies of light. Certain frequencies of light can blur vision, and others can enhance contrast. Choosing the right color for your sunglasses lets them work better in specific situations.
When you buy a pair of cheap sunglasses, you often give up all of these benefits and can even make things worse. For example, if your sunglasses offer no UV protection, you increase your exposure to UV rays. The cheap sunglasses block some of the light, causing your iris to open to allow more light in. This lets in more of the UV light as well, increasing the damage UV light can cause to the retina.

Ok you always have to have a clown in yahoo so this time it will be me so here it goes. I will answer your question.
The polarized are made from "polar" bears so if you are an animals rights activist, you should be sentenced to jail for buying them.
The U V Ray glasses were worn by Ray Charles and when he was asked to come up with a name for them, he accidentally hit the letters, U instead of the I and V instead of B.
He was attempting to advertise them using the Slogan "I B Ray. Of course he was blind so he couldn't see the keys when typing. So now you have it! So the next time you have them sun glasses on, just say I B Ray.
