I don't think normal glass does a good job in filtering out UV hence the UV filtered sunglasses etc. I think it does some, but if you want to target it specifically, you may need to get some from a glass shop.
If this is true, then you should look to getting some as prolonged exposure to UV light can damage your eyes causing cataracts, etc..
I know that my hood, when I bought it said it has UV filtering glass.
