TrueDark by Dave Asprey | Twilights Red Lenses Block 99% Blue, Green & Violet Light for Night Use

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.

If you have used cheap blocking glasses in the past - brace yourself. These are seriously next level. Yes, they are quite spendy but wow. You know those blue indicator lights on things like washing machines etc? Yeah - I put these on and those completely disappear. I will say that watching something online with these on is a bit 'different' because of the spectrum blocking. Oh well. These are also comfortable to wear, and the sides block out stray light well. Highly recommend. TrueDark's are what other blocking glasses wish they were.

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).

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'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

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.

I have been taking multiple seminars on natural health and healing as a way to prevent illness and chronic fatigue, increase energy etc. A consistent message regardless of who you listen to is the importance of SLEEP! A couple doctors and experts specifically suggested the red glasses for night and the yellow for day. I doubt I will get over my bad habit of watching TV or reading emails before I go to bed so instead I tried these glasses so at least that activity didn't mess with my circadian rhythm. They work amazing. I get to sleep MUCH faster, about 20-30 minutes of screen time as opposed to 1-2 hours. I live in the city so no matter where I go my house has outside light shining in through the blinds so I have slept in these which are perfection. They are very comfortable with a soft rubber inside around the eye part to close off the light from getting in the edges. I am a back sleeper so it was very comfortable to have them on and they were perfectly in place when I woke up. I have been able to sleep completely through the night when I normally would wake up 3-4 times. I naturally wake up after 8 hours which is the ideal time and feel rested for the first time in a long time. I was skeptical but splurged because I had so many sleep issues and these came highly recommended by many educated people studying sleep that I trust. Well, it certainly worked for me. For those that complained about light getting in from the sides, I did not have that issue. It could be the shape of your face but I have a fairly large round head for a woman and they fit snugly on my face with no light coming in from the sides.

I purchased the glasses to use as cover over for my prescription pair . Unfortunately they were to small and would not fit over my pair. Beautiful style sorry it did not work for me

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.
