This is a good, brief article on how to help your vision when you’re stuck using computer screens for much of the day. Too many of us have to sit and work on a screen that isn’t usually a top-of-the-line screen for work and then we sit and use a smart phone whenever we’re not on the PC. We drive home and then watch TV or play a computer game or maybe read a book on our tablet until bed. Can that much screen time be bad for us? What does staring at those little lighted pixels do to our retinas in low light? Good questions that are answered in the article.
