Gamma Ray Blue Light Blocking Glasses - Orange Tin Lens Blocks 98% Blue Light - Better Sleep Before Bed Night Time Digital Screen Glasses - Eye Strain Insomnia Reducing Computer Gaming Glasses

It's very helpful if you spend a lot of time on front of computer screens

I was doubtful about this one, having used many others over the years. But all them were just useless as they would never reduce my eyestrain. This one brought a dramatic turn in my life. I can now look on laptop screen for 12 hours without having to worry about my eyes. Yes they distort the colours, but after continuous use, I have become used to it. As they say "allow 7 days to adjust'. I allowed, and boom.

These are great for outdoors in the bright sun. I wear them while riding the motorcycle and it helps to see clearly as well as block the bright blue light and I noticed I havnt been getting the small headaches I usually get after being in the sun for too long. Crystal clear lenses as well

Fantastic product. Don't go for cheaper alternatives. Get Gamma Ray. Will help you work better, for longer hours, and sleep better. Use it anywhere you are in LED light.
