Vision Needs

Computer Vision Syndrome

If you use a computer regularly, you will probably suffer from Computer Vision Syndrome (CVS) at one time or another. But don't panic: CVS simply refers to a combination of eye and vision problems associated with computer use, and about three-quarters of computer users have it. However, you should take certain steps to alleviate your symptoms so they don't get worse.

Computer Vision Symptoms

The most common symptoms of CVS include:

• Eye strain or eye fatigue.
• dry eyes.
• burning eyes.
• light sensitivity.
• blurred vision.
• headaches and pain in the shoulders, neck or back.

Causes and Treatment

CVS can have multiple causes, so there is an arsenal of steps to take to free yourself of pesky and painful symptoms.

Problems with your eyes (eyestrain, dry eyes, burning and light sensitivity) during computer use can result from: insufficient tear flow to the eyes, too much glare and reflection on the monitor, monitor settings that are hard on the eyes and needing vision correction (for the first time, or a new prescription). So where do you start?

First, treat the problem that affects virtually every computer user.

You're Not Blinking Enough

Three simple tips can overcome the problem.

1. Think about blinking. Make a conscious effort to blink more often. Put a note on your computer if necessary.
   
2. Take a break. Several times per hour, take a minute to look around at things that are at varying distances from your computer, like a clock on the wall, or something outside a window. Or, take one big break, about 15 minutes, per hour.
   
3. Use eye drops as needed. Look for the ones marked "lubricating" or "lubricant," as other kinds can be addictive, even in over-the-counter strength.
   
4. If wearing contact lenses, it is helpful to wear materials which stays hydrated on the eye such as Proclear Compatibles lenses. Proclear Compatible lenses are the only soft contact lenses with the FDA claim: "may provide improved comfort for contact lens wearers who experience mild discomfort or symptoms relating to dryness..." See your eye care professional and ask about ProClear Compatibles contact lenses specifically designed to combat dry lens, and lens discomfort.

Second, see if glare and reflection are affecting you.

Glare and Reflection

Both office lighting and sunlight can create a lot of glare and reflection on your monitor. Trying to see through these twin troublemakers can really make your eyes weary in a hurry. Here's what you can do:

1. Position your computer so that any windows are to the side of the monitor, rather in front or in back.
2. Adjust window blinds so that the sunlight is away from your screen and your eyes.
3. Turn off overhead lights that are too bright. If this turns out to be not bright enough, switch to a lower wattage bulb, or use a desk lamp.
   
4. Move your desk lamp to a spot where it doesn't reflect on the screen or shine in your eyes.
   
5. Attach a glare-blocking hood to your monitor. Much as a jacket hood can reduce the amount of sunlight that reaches your eyes from the top and sides of your head, a monitor hood reduces the amount of light that can reach your screen.
   
6. Attach a glare filter to your screen. Filters are readily available from office supply stores, but you may need to look online to find a hood for your computer. Less common sources of glare and reflection are office walls and desks, particularly bright white. Think about a paint job or a new desk if you find these surfaces to be giving you trouble.

Third, make a few small adjustments to your monitor for fast CVS relief.

Take a look at your monitor right now. Is it a reasonable distance from your eyes? It should be about 20 to 26 inches away. Is the screen covered in dust? Is your document holder near it? For heaven's sake, clean your monitor every now and then! How do you expect to see through all that dust? And, make sure you place your document holder as close to the screen as possible: constantly looking back and forth between them can tire out your eyes.
