Plastic eyeglass lenses have a colorless UV absorber in the lens material. If not, the lens will yellow after a few months of exposure to the sun. That doesn't stop the promotion of UV or blue light blocking lens material as having a benefit. Any additional UV protection is superfluous. Any blue light 'protection' is based on questionable science.
Ignore the attempts to empty your wallet.

Some plastic lenses do, but not all. My husband actually tested this and wrote it up in his blog! https://savemaple.org/2022/12/16/1658/

Nice writeup! The question then becomes which wavelengths of UV are harmful. Plastic lenses have UV absorber that blocks up to 370-380 nm.
