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.
