My son works in front of a screen many hours a day and has been complaining of poor sleep. Wearing night glasses with the yellow lenses- 70% blue light block has been very helpful. He says he wears them at night and within an hour he feels sleepy and sleeps well the entire night. He says he is amazed how well the technology works. He also wears clear lense glasses through the day and says even those make him sleepy during the day so we decided he should wear them on and off through the daylight time. I feel that’s the best gift I’ve given him in years. I love my pair of glasses and was able to get my night sleep better since then, that’s why I gifted my son. One more son to go and we are all set. Thank you blue block.

I work in a restaurant so for ten hours a day I'm under artificial lighting and looking at an iPad for taking orders as well as other to go tablets. And of course when we're not busy I tend to be on my phone.

Around the middle of the shift I noticed my eyes would get really tired and I would have a mild headache. I never thought anything of it (just figured I didn't get good sleep and needed a mid-afternoon nap). But I would say that the tired eyes and headache I normally get during my shift have been mitigated by at least 90% when I wear these. The reason I suspect it's not higher is that I have a compulsion to occasionally remove my glasses and "see how well they were working". So I would imagine the results would be better if I just kept them on as much as possible.

I thought they would be a little bigger when I put them on for the first time, but they've grown on me. Maybe my head is just large. My main issue with them is that they are an oil magnet for sure. I have to spray the lenses generously and spend at least a few minutes carefully wiping to get them close to spotless. They probably pick up grease from the restaurant too, so if you're in an office environment or similar you might have better results.

Overall I'm very happy with my purchase and I look forward to the next ones.
