What does UV lens do. Does it eliminate glare from sunlight and light from inside the house. I am trying to get rid of glare from windows. I currently have polarise lens but they only reduce glare if i am behind the sun light.

No. From what I've seen, the most important thing it does is protect your lens. When you are shooting outside on sunny days, I guess it is supposed to reduce haziness from UV rays. However, I haven't seen any major noticeable difference. But still get a UV filter, because it'll be worth it for your lens. As for removing glare, polarizing filters work well, and also a lens hood. If you can't attach a lens hood to your camera, just make one out of black posterboard mounted on cardboard, and it should be pretty self-explanatory. Hope this helps!

You have misunderstood the difference between frequency and velocity. All frequencies of electromagnetic radiation - including visible light, radio waves, gamma rays etc - travel at the same velocity in the same medium. You can change the frequency of light, moving it into the gamma ray or ultraviolet spectrum, but all this does is proportionally change the wavelength. The *velocity* of the light does not change. Velocity *does* change when light moves into a different medium. This is why it's more correct to talk about 'the speed of light in a vacuum', although the difference between this and speed in (eg) air is not great.
