TrueDark Twilights by Dave Asprey | Nighttime Blue Light Blocking Glasses

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.

Amazing. These glases are so good, and the design is clean and robust as well. 10/10. will recommend this. They came in 1week before as well.

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).

I've tried a few blue light glasses and generally been scammed thus far. This is my fourth pair of glasses that purport to block light for sleep, but the first I've ever tried that actually do it. The build quality is definitely bad imo, don't get me wrong. The arm of the glasses doesn't fit quite right and won't open all the way and it feels cheap like it's about to break. I don't care about the looks of the shades themselves. The packaging is really nice, the collapsible case they come with is primo. The lenses do genuinely block blue and green light, as I expected red lenses with the right filter coatings to do. It's crazy to see compared to the cheap dogshit fake ones that are very popular on amazon, of which I bought several. Search for "blue light test image" and find something with black and blue mixed together. If the glasses actually are blocking blue, then the image would look all black. Same goes for green in this case since they block both (most amber/orange colored lens sleep glasses only block blue). There are a ton of ways to see the blue blocking effect but until you see it for real it can be hard to know what to expect, and therefore very easy to fall for literal rose colored glasses that don't block jack tldr it's harder than you might think to find actual blue/green blocking sleep glasses, but these ones actually do work which helps offset the price and build quality

Great product works

Very pricey but its amazing at the light that it blocks out. I put them on while watching tv or reading and get the light contact from my eyes and within 15-20 minutes I'm usually yawning. If you care about your sleep and are having trouble with it I would absolutely say get a pair of these. They're the best of any that I've ever wore for removing different wavelengths of light.

I was disappointed in these glasses. I had such high hopes. 3 of us in the family tried them. They gave us headaches. None of us could wear them for an hour. We gave up after 5 - 20 minutes. We could not do any of our regular evening activities. It was very disorienting. As for construction, they are made well and fit our faces even though we are all different sizes. I am not sure if it was the fact that we all normally wear prescription glasses that did us in.

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.
