IBOANN Round Blue Light Glasses for Women Men - Vintage Metal Bluelight Blocking Eyewear Frames w/Anti Uv Lens

I like scrolling facebook and watching videos while lying down before falling asleep, but I seem to end up staying up so much later than I intend to. Since starting to use the glasses I've noticed I feel tired even after just being on my phone for a short period of time. I do feel like they truly do filter out the blue light which is so much easier on my eyes. They are comfortable to wear and look quite stylish when I use them throughout the day as well.

They arrive with a small square of white paper and a smaller blue light.Shine the blue light through your lenses and it will not show up on the square.If you are closer than 6 inches, yes it will show, but who will get that close to their PC screen?They supply you with two pairs of glasses, mine are rose gold and black: two cases, your test materials, and a lens cleaning cloth.After a 5-hour session of business dealings, I was very grateful for these.

Wife and I got these and they are nice looking and comfortable you don't realize you are wearing them. Work great for eye strain. I use daily.

My wife says these are comfortable, and blocking blue light, especially for a while before bed can help you get to sleep more easily. They also block UV. An unexpected benefit is that she says things are a bit sharper. I taught astronomy for a long time, and telescope makers deal with something called chromatic aberration. This is the fact that different wavelengths don't bend the same when going through a lens. That's why prisms create rainbows. Blocking one wavelength help minimize this.
