When you see blue light in glasses you can usually see the reflection of blue light on the lens. You can't with these. They come with blue light and test paper, by the looks of it they seem to be working and they've done a good job of helping me get rid of my headaches and eye strain. Reflecting only blue light is a nice aesthetic, just so it doesn't look like you're wearing a useless piece of plastic. I've had them for about 2 months now and the lenses seem to have an odd yellow tint and are almost impossible to clean. But I'm ordering a new pair elsewhere. You get what you pay for so 2 pairs is good at this price and I would say they work. Just keep in mind that they may not last long, so there's no harm in investing a little more. They also fit/look good on the face. I deducted a star for the lack of blue reflection on the lenses and the odd yellow cast/can't keep them clean.
