As advertised.
I bought these "blue blockers" because I read that wearing them before bed time would help overcome the negative effect of tv and computer screens on melatonin levels. I don't know if that's true and wearing them that way was too distracting, so I didn't give them a fair test. However, I do enjoy wearing them while driving on long distance trips. They seem to be relatively well made and they fit over my regular glasses.
