Twilight Classic Sleep Hacking Blue/Green/Violet Light Blocking Glasses - Protect Your Eyes from Harmful Computer Junk Light

Expensive but they’re really the best. Super comfortable, blocks all the green and blues, you will start to feel drowsy before bed even if using phone or laptop.

Los llevo usando unas semanas y ayudan bastante antes de dormir, son muy relajantes para la vista aunque si toma tiempo acostumbrarse a ellos. La calidad no es muy buena, son de plástico pero no he tenido ningún problema con ellos.

Great product works

I don't see any blue or green LEDs on my appliances and other devices when wearing this glasses. I mean it's 100% block! Impressive. By the way, the other glasses of Dave Asprey don't do a full block, even lens color may seem the same.

This product follows the science of blocking out all wave lengths except red. I’ve tried many products and this is by far the most comfortable and has the least light leakage if any. I get drowsy as soon As I put them on. They are expensive but so is buying 5 cheap pairs that don’t work, leak, are uncomfortable etc. please keep supplying this product. It is required lifestyle medicine to make exogenous melatonin work properly in the body as a free radical scavenger, mitochondrial booster, and promoting senescence and oncostatic properties.

Overall: Extreme cheap product quality better priced at $20. A different Amazon vendor sells the same frame with the same lenses for 50% less. Search for safetey blue sleep savior. RETURNED IMMEDIATELY AFTER OPENING. The frames: These are easily the lowest quality glasses frames I have ever seen or owned. It is an extremely light weight and brittle plastic. If you fell asleep on these, dropped them, or accidentally rolled over on them, they would definitely break. Feels like foamed ABS plastic - think 1980s car interior. The Lens: The lens is a very deep red which likely blocks the advertised spectrums. The lens is relatively thin and doesn't distort vision. It does reduce light transmission on all spectrums pretty strongly, so note that using in very low light or the dark is likely not safe. The Fit The frame is made for wider heads than mine. While brand name sunglasses fit with no issue, these are wide enough that the foam didn't seal against my face at all. While the cheap plastic is very light, the plus is you likely forget you're wearing them (other than the deep red hue that everything takes on).
