Review on Fetrrc Reading Blocking Computer Eyeglasses by Dorvin Hawk

I bought these glasses because I always lose scam readers and as there are a lot of them I wouldn't cry if I lose one. If I can get a few weeks or months of them, they're worth it. The colors shown are not correct, but I will not wear them in public. The size is smaller than expected and designed for small heads. When it comes to blocking blue light, which is great for reading the evening news or watching TV before bed, they fall short of other budget brands bought elsewhere. What struck me is that lenses with blue light blocking technology really work, especially to help fall asleep and maintain sleep. Although I'm keeping them (hassle returns and they were good value) I'll buy another pair or two that fit and have better blue blocking. They were bought because they would arrive quicker and a big disappointment. Here's a quick way to find out if they really do block blue light: grab your phone and open any website with a white background. If the background looks slightly off-white, they work. They don't block anything but can be used as inexpensive readers for smaller heads.
