Preventing Computer Vision Syndrome

 

The average person spends seven hours a day looking at a computer screen. Eyes can be strained when you view television, computer, tablet, or smartphone. In fact, over half of all computer users, including children, now show symptoms of Computer Vision Syndrome (CVS).

 
 

What Happens if I have CVS?

 

Some of the warning signs of CVS are:

 

  • Blurred vision

  • Double vision

  • Redness

  • Dryness

  • Irritation

 

CVS can also affect more than the eyes. You can also experience the following problems caused by CVS:

 

  • Headaches

  • Neck pain

  • Back pain

 

The eye care professionals at Trinity Eye Care can assist in diagnosing CVS, and provide a prescription to relieve your symptoms, increase your quality of life and improve your job performance!

 
 

How to Prevent CVS

 

Fortunately, CVS symptoms can usually be treated and reversed with a few small changes.

 

Change the Brightness Settings – Use black text on a white or slightly off- white color scheme. Hold a piece of white paper up to the computer screen document. If the screen background is brighter or darker than the piece of paper, go into your System settings, and reduce or increase the brightness of the screen to match the paper brightness.

 

Change the Refresh Rate on your Computer Monitor – The flickering of the computer monitor can cause eye strain. Most computer settings have a refresh rate of 60 MHz. Increase the rate to 72 MHz or higher to reduce your eye strain.

 

Use a Blue Screen Filter – Use an application to filter out the blue color of the screen to prevent CVS. 

 

Font Size – Increase the font size so you can read without straining your eyes. After the age of 40, the font size may need to be steadily increased. 

 

Reduce Glare – It’s essential to reduce the amount of glare that comes off your computer screen. Try to change the angle of your computer screen so that it doesn’t reflect light back to your eye. Purchase a glare filter and mount it over the face of your monitor. If you have natural light in your room, adjust the drapes or blinds to reduce or block the light.
 

Position Your Screen – Your ideal monitor position is just below your eye level (about 10 degrees lower than your eyes) and about 20-28 inches in front of your eyes. You shouldn’t have to change your head position or strain your neck to read what is on your screen.

 

Take Breaks – Your breaks don’t have to take up much time. Doctors recommend using the 20/20/20 rule. That is, every 20 minutes, look at an object 20 feet away for twenty seconds. If you feel eye strain, get away from your screen for a few minutes.

 

Use Eye Moistening Drops – You will not blink your eyes as often when you are looking at a screen. You can get dry eyes if you don’t blink enough. Use an over-the-counter eye drop to moisten your eyes three times a day.

 

Add Computer Distance to Your Prescription –Even if you don’t normally need glasses for reading or distance, an anti-glare coating on computer glass lenses can help to reduce all the glare that passes through the lens to your eye.
