Adjust Your Work Area
If your computer is not properly positioned, you may find yourself experiencing eye strain and visual fatigue. Make sure that your computer’s screen is at least 24 inches away from your face and that the screen itself is directly in front of and also slightly lower than your line of sight.
Dry Eyes
Poor ventilation, dry air, and dust can cause eyes to become red and irritated since tears may not properly coat and moisten the eye. When reading or using a computer we tend not to blink as often, which can actually make the issue worse. When you are reading or looking at your computer screen for extended periods of time, be sure to take breaks and remind yourself to blink.
Follow the 20-20-20 Rule
Focusing on your computer screen for extended amounts of time can cause your eyes to become fatigued. That’s why it is so important to give your eyes a break by following the 20-20-20 Rule; after 20 minutes of computer use, look at something 20 feet away for 20 seconds.
