I find this spec's to be great in quality, looks, fitting and comfort. It definitly cuts out the color's it claims. It also comes with a nice collapsible carry case that easily fits in your pocket.

This product is a game changer for me. When used, I instantly feel the deregulation and downtime turn on, things become dark, my eyes feel a lot less strained. Granted, you need to use these glasses in conjunction with other techniques like trying to stay away from the TV or any devices, or not doing anything that requires full use of your eyesight. But when done properly, I feel that my circadian rhythm is being better managed and observed.

(Reviewed by Aubrey’s husband) - So I’ve had a hard time sleeping for more than 4 hours per night for a number of years now. I’m fortunate to be professionally successful but the lag has been making it harder and harder to focus at work. We go to bed at 8:30 because my wife has to get up early, so I lay there looking at my iPad on the lowest light setting (Netflix, speed chess, video poker, reading, whatever) until maybe 12:30 — 1 AM. I fall asleep until light comes into the edges of my blackout shades - then I’m wide awake at 4:30 or so. I work from home and my day starts around 7:30 AM, and I’m dead tired by that time. I have ear plugs, the aforementioned blackout shade, multiple high-end eye masks (memory foam is my favorite), etc. I ordered these glasses and just had one of the best night’s sleep I’ve had in a long time. I slept from about 11:00 - 11:30 PM straight through until 6:30 AM - a home run for me. They feel sturdy and appear to be of good quality, and they work so far. Here’s why I can’t give five stars - they’re not sealed in any way so you’ll get blue light from the top, bottom and sides. I would be even more impressed if they came with a gasket of some sort, like motorcycle or ski glasses. I’ve just ordered two different brands - one that consumer reports rated as the best for blocking out blue light (but I believe they’re cheaply made) and another pair that’s a little less than these ones but which also have the gasket. I haven’t received those yet but may update once I have. Oh - one last thing - they should make these in magnified readers. To heck with having to put them over existing glasses which is bulky and uncomfortable (no I did not purchase the ones that go over reading glasses - I want some that ARE reading glasses).

These blue light glasses areamazing- they don't fog up like the others! So glad that I bought them!

Great product. I wear at night before sleep. It helps me relax.

Great product for computer or general use. Not good for gaming. Makes the screen to dark.

These Glasses do the job they were designed for very well except for the Nose Pads.

Great quality product and fits the face really easily with expendable sides. Indispensable when working or watching a movie in the evenings.

First impression: Box came brused but glasses was intact. The case it shipped with will not provide adequate protection for the glasses (in my estimation) and prevented me from traveling with it on a 15 hour flight where I could have tested them 😔 but I hope to test it soon. So far so good. Case should have been way better for the cost of the glasses. Little light protection from the sides with this frame but it's as designed. Comfortable and light weight, good looking pair. Just need to test its effectiveness. Rather pricey. Ship with a better, stronger more protective carring case. Another review to come

Se sienten cómodos, se perciben de buena calidad y definitivamente bloquean la luz azul. Sin embargo, están un poco caros.
