Of course. Just consider sunblock that we use on our skins to stop us burning. Sunglasses also filter out UV light to protect our eyes. For pretty much any wavelength of light, you could find something that absorbs it.

What about a 10ft-thick lead wall? That'll block most things.

On a more scientific note, consider a UV spectrometer. An instrument we use to calculate concentrations of something in a solution according to how much UV light that solution absorbs. UV light is blocked from reaching the detector by molecules floating in the solution. If we have a very concentrated solution, the absorption rises (if it blocks the specified wavelength).

So we can see that UV light is just as blockable as any other type of light, albeit perhaps using different things.
