These blue blockers are amazing. I had some from another company with clear lenses and never noticed much of anything. With these Sunset glasses, you feel it. You calm down. You get sleepy when you should and you fall asleep when you should. I highly recommend them.
Everything slowly shuts down once I put my glasses on around 8 PM. I get very sleepy and I don’t have irritated eyes anymore when trying to fall asleep. Crazy glasses!
