Staring at a computer screen for too long can cause:
-Trouble focusing at a distance
-Neck, back, and shoulder pain
Take the following steps to protect your eyes:
-Make sure your glasses or contact lens prescription is up-to-date and adequate for computer use.
-Some people may need glasses to help with contrast, glare, and eyestrain when using a computer.
-Position your computer so that your eyes are level with the top of the monitor. This allows you to look slightly down at the screen.
-Try to avoid glare on your computer from windows and lights. Use an anti-glare screen if needed.
-Choose a comfortable, supportive chair. Position it so that your feet are flat on the floor.
-Every 20 minutes, rest your eyes by looking 20 feet away for 20 seconds. At least every 2 hours, take a 15 minute break.
