I'm a Type A personality, so when it comes to my health or that of people I love, I do a ton of research. Always online. One of the things that helps my eyes when I'm on the computer all day is a Chrome extension called BeeLine Reader. It changes the color of the text you're reading over a gradient from blue to red. It's hard to explain, but it's free and worth a try. It's a great tool for people with dyslexia and people with attention issues (ADD/ADHD).
