What are the difference between acetate and plastic glasses?

[Everett]

The nose pads of normal plastic glasses have the same color as the frame because these materials are injection molded while acetate plastic glasses have clear end pieces on the nose pads which are attached to the frame because these frames are cut from the sheets of acetate plastic.

I am not sure the difference between them.They have something similar. The seller in the optical store may tell you the difference between them.
