I asked my optometrist about them and she said there wasn’t enough time for research to determine if blue light lenses would be effective or not.
Personally I have not got them but more curious now.
Had a checkup yesterday, and the astigmatism in one eye is worsening (still not bad enough to require glasses). My optometrist recommended blue filtering glasses, but made no definitive statements about their effectiveness, research- or colloquially-supported.
