Review on BlackRain Lightweight Computer Prevents Headache by Gary Wainwright

After I put it to the test these glasses really DO work! No more headaches after hours in front of the computer. They're lightweight and comfortable, so I hardly even notice I'm wearing them. The blue light blocking technology is a lifesaver .My only complaint is that they can sometimes slip down my nose a bit, but adjusting them is easy enough. Overall, a great investment for anyone who spends a lot of time on computers..
