Many of us experience eye and vision related difficulties after prolonged use of our computers, tablets,e-readers,and cell phones. These difficulties, grouped together, are called Computer vision syndrome (CVS). The level of discomfort usually appears to increase with the amount of digital screen use.
The most common symptoms associated with CVS are;
- eyestrain
- headaches
- blurred vision
- dry eyes
- neck and shoulder pain
There are a number of factors that determine the amount of strain your body feels as you work on your computer or other digital device, including lighting in the room, distance from screen, glare on the screen, seating posture, and the angle of your head - preexisting vision problems are also contributory factors. One or all of these combine to cause an uncomfortable amount of strain in your eyes.
Many of the visual symptoms experienced are temporary and usually decline after stopping computer work or use of the digital device. However,some individuals may experience continued reduced visual abilities, such as blurred distance vision, even after stopping work at a computer. If nothing is done to address the cause of the problem, the symptoms will continue to recur and perhaps worsen with future digital screen use.
MANAGEMENT OF COMPUTER VISION SYNDROME - Make sure the lighting in the room is comfortable on the eyes, and prevents you from staring into glare on the computer screen.
- Position the digital display so that your head is in a naturally comfortable position while using.
- Take breaks : follow the 20-20-20 rule; take a 20 seconds break to view something 20 feet away every 20 minutes.
- Make sure your seat is comfortable. A comfortable chair with support for your neck and back will help you avoid neck shoulder strain commonly associated with CVS.
If symptoms persists, consult your Optometrist
