Computer Use Computer images are created from thousands of tiny dots – so there is no distinct image for your eye to focus on. You have to focus and refocus to keep the images sharp – and after two hours you can end up with the same kind of repetitive stress in your eye muscles that the keyboard causes in your wrists. You can reduce the impact of computer eyestrain by following a few simple rules: Keep your computer screen within 20"-24" of your eyes Keep the top of your computer screen slightly below eye level Minimize the distance between your computer screen and any documents you need to reference while working Adjust lighting to minimize glare on the screen Blink frequently Take a break every 15 minutes to focus on a distant object
