This is by far the best Blue Blocker I have and I have bought and tried many

I have the lumos sleep mask that helps me when traveling internationally to regulate my sleep rhythm pattern (jet lag). At home I fall asleep easily, but I tend to wake up in the middle of the night and frequently can't fall back asleep. I tried the Blue Blocker with and without the sleep mask, but alas, it didn't make a difference. It might help people who have trouble falling asleep though.

Got these for my parents as they both watch tv at night with prescription glasses. They both said these were extremely comfortable and effective! Super pleased!

I've used several blue light blocking glasses, and these are by far my favorite. They are comfortable and I love that they have shields on the sides too. I wear them for a couple of hours before bed and find that my sleep is much better.
