TrueDark Twilights Classic Blue Light Blocking Glasses - Reduce Eye Strain and UV Glare for Better Sleep - Men & Women - Computer Screen, Gaming, TV, Phone - by Dave Asprey

Have been using them for years now and have definitely improved my sleep quality by blocking the blue/ green lights before bedtime. The design is unique and covers also the top and sides of the eyes so that no (blue) light comes in from the top or the sides, if it fits correctly. Only thing I noticed is that the screw on side has come loose and needs to be tightened and also the foam padding on the left has worn out, so wish it was more durable!

I use these glasses to watch TV at night. Everything goes a kind of red black and white but you do get used to it. Does it work? By not telling my brain that it is daylight (all the blue light from the TV) I fall asleep faster and stay asleep. I believe that they do help. I have a small head/face and find that they are a little large for me, but I can still wear them comfortably.

I bought these glasses after an interview with Dave Asprey and the Sleep doctor and as nobody sells them or something similar in Germany I bought them from the US. And the glasses work I have to say. When I put them on round about half an hour before I like to hit my bed, I get tired and fall asleep faster than before. And as I live with my family and they don't want to dim all lights in the evening they are a great alternative.They are not looking "cool" on me (my family says I look like a fly) and I find them a little bit too expensive, especially with shipping costs and costum duties.

I like the lenses and the design but for this much money the quality is HORRIBLE. If I didnt know I would have guessed these costs at most $10.

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 jacktldr 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

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 love these glasses. They really work well.

i love them but they have ONE LITTLE BIG PROBLEM.. one of the crystals fall off very easily... like it goes back in if you do the work... but it is def not ideal.. You have to treat them as if they were very delicate and that makes them not as cool as they could befreakin 80 plus dollars one would expect better qualityEstán buenas para dormir y demás pero uno de los lentes se cae facilmente.
