What is Blue Light and how it affect our eyes

Joel Parker20 Dec, 2021Health

These really do work, I can see them reflecting blue light back out, and looking at a screen is noticeably less harsh. I've only had one headache in a week since using these, as opposed to having one every day before, and my eyes feel so much healthier and more focused. I'm seriously blown away by how much of a help these have been.
