In brief: Block light

The eye works like a camera.
Glasses function like focusing the camera lens to give the sharpest image. However, a cataract (a clouding of the natural lens in your eye) is more like having dirt on the lens of the camera. This dirt will block the light and decrease the image quality even if the lens is in perfect focus.

In brief: Block vision

A cataract is the clouding of the natural lens in the eye.
If the lens is no longer transparent, placing a spectacle prescription in front of the clouded lens in your eye will have no significant affect. An analogy is: if you put a clean piece of glass in front of a clouded piece of glass is the view still blurred--yes.
