Guardian Over-The-Glass Safety Glasses with Large Yellow LensFredelApril 15, 2012I'm one of those people who is on the computer late at night. I had been having major trouble falling asleep. Now, I put these glasses on about two hours before bedtime, and they have made all of the difference! I highly recommend them to other computer-night-owls. I understand that they help if you're a late-night TV watcher, too, but do not have personal experience with this, since I'm not a big TV watcher (who needs to be, with so much available online??).
