Many of us spend most of our day staring at computer screens, smartphones and tablets. Staring at these devices for more than two hours a day puts you at risk for eyestrain, headaches, dry eyes and general exhaustion.
According to a recent New York Times article, computer vision syndrome (CVS) is different from other kinds of eyestrain because of how we view electronic devices. When you look at a computer screen, not only must your eyes stay focused, they must converge inward for extended periods of time.
To treat computer vision syndrome, you should have your eyes examined to rule out other causes. You may need to have your prescription updated as well. If symptoms persist, computer glasses may be suggested by your eye doctor.
- Have special coatings to reduce glare.
- Are tinted to reduce eye strain.
- Are designed to provide clear vision at intermediate distances.
You can prevent CVS symptoms by increasing the size of font on your mobile device, and by using the 20-20-20 rule: Every 20 minutes, look at something 20 feet away for 20 seconds. This exercise lets you relax your eyes from focusing and converging strain.
