Getting headaches, blurry vision and tired eyes after a day of working on a computer? There’s an easy answer: Computer glasses!

The strain on your eyes from working on a computer is a real condition, and it even has a name: computer vision syndrome (CVS). Experts say that looking at computers simply requires your eyes to work in ways that other activities don’t.

Wait a minute, you say. I already wear glasses. And I still get blurry, tired eyes.

There are reasons for that. Ergonomics experts – the folks who measure how your body performs tasks – note that most computer screens sit 20 to 26 inches from your eyes. Your eye doctor calls this range the intermediate zone of vision – closer than distance vision (like when you drive), but farther away than reading (your “near” vision).

Without computer glasses, people often lean forward or backward to compensate for the visual range. So you get to the end of your day not only with the symptoms of CVS, but you get sore shoulders, a backache or a sore neck as well!

Most people under age 40 who wear glasses get them to correct their distance vision. Those of us over age 40 often get eyeglasses to correct the onset of a condition known as presbyopia – the loss of focusing ability that’s normal as we age.

The problem is, eyeglasses made to correct either of these conditions don’t address what’s happening in the intermediate zone of vision – that space between you and your computer screen! Even bifocals, trifocals and progressive lenses aren’t made for computer-range vision.

Recent research has supported the use of computer glasses. The University of Alabama School of Optometry studied the vision of computer users ages 19 to 30. Study participants were chosen randomly to wear either computer glasses or non-corrective eyeglasses. The researchers found that even when CVS symptoms weren’t reported, workers clearly showed differences in their productivity and accuracy.

So you can just pick up a $20 pair of computer glasses at the local office supply store, right? Well, maybe. The advantage to buying off the rack is clearly price, but if you have other vision problems, those single-lens glasses might not be the best for you. Experts say the trick to getting that $20 off-the-rack pair is to test them by reading something that’s the same distance from your eyes as the computer screen — 20 to 26 inches.

Glasses from eye doctors come in what’s known as “multifocal” styles. These can be bifocals, trifocals or occupational progressive lenses. The advantage to these more expensive styles is that you’ll be able to see clearly whether you’re looking at your computer, reading notes on your desk or winking at that cute co-worker across the cubicle from you. The drawbacks, of course, are that these styles require a visit to your eye doctor and usually cost around $300 or more.

Either way, be sure to check out your new glasses by working on your computer. If the blurries don’t go away, get another pair!

With new technology comes new issues and potential problems. Computers have been around long enough that not only do we have constant technical difficulties as each computer manufacturer seeks to update, but physical ones as well. Like the need for computer glasses.

It has been discovered that sitting in front of a computer screen not only makes you a pain in the neck and causes a creak in your backside, but it gives you eye problems as well. Even if you are currently wearing a prescription pair, you may want to purchase yourself a pair of computer glasses. You can also purchase attachments to go along with what you already have.

Computer glasses are specially made. In regular prescription glasses, including bifocals, you usually find help in seeing better at near ranges or far ranges. Except for a minute portion of trifocals, you do not have the mid-range needed for comfortable computer use.

If you spend long hours in front of a computer, you may want to get computer glasses, whether or not you have to wear corrective lenses. Computer Vision Syndrome can cause a multitude of symptoms, leading to loss of productivity. CVS can cause headaches, blurred vision, neck and shoulder pain, loss of focus, tired, burning eyes, and double vision.

If you are over forty, some of these symptoms may be presbyopia and needs to be checked carefully by your eye doctor. For those under forty, you likely have a case of CVS and need computer screen glasses. If you do not wear a prescription pair, then you may want to get computer glasses anyway, as they also help with the glare from fluorescent lights. Your best bet would to go to your eye doctor and ask for an exam and order a pair.

The simplest pair of computer glasses you can order would be the single vision lenses. Their modified power helps keep the general user from some of the discomforts associated with CVS. For people with presbyopia, the occupation progressive lens, would probably work best. The transitions zone is much larger than your typical progressive lens and can even do some distant vision for you. They have improved computer vision near and far as well as the middle zone. However, they are not substantial enough to drive with. These glasses are not made for driving.

For some people it may be beneficial, even if not strictly necessary, for them to get an occupational bifocal. If you need reading glasses, this could be a good option. A portion of the lens is dedicated to close up work and the other portion to mid-distance work for working on the computer.

Again, go to your eye doctor for best results. And don’t wait until the symptoms are so bad that the possibility of permanent damage comes into play. Ask your optometrist what would work best for you. They will know the which computer glasses are the best for your eyes and will do you the most good in form and function.

Computer Glasses – Do You Need Them?

If you have reached the point where you need reading glasses to read a book then you probably need computer glasses while using your computer. Why? Reading glasses are designed to help you see clearly while reading text about 12 inches in front of you. If you use these same glasses while using a computer you still have to keep your head 12 inches from the text but now that text is being displayed from a bright computer screen. Staring at a computer screen from this distance can hurt your eyes.

Your eyes may start to become sensitive to the light. Your eyes might start feeling strained and dry. Your vision might start becoming blurry. You may start getting headaches while sitting in front of your computer. All of these are signs of Computer Vision Syndrome. People who are suffering from Computer Vision Syndrome (CVS) may not even know why their eyes are bothering them.

People with normal vision sit 18-24 inches from a computer screen during everyday use. Computer Glasses allow you to sit the proper distance from the computer screen and still see the text clearly. This will help reduce the effects of Computer Vision Syndrome. As time goes on people will hear more and more about the damage computer monitors are doing to our eyes and how computer glasses can help prevent much of this damage.

If you are one of those people who needs reading glasses to read a book do yourself a favor and use computer glasses while sitting in front of your computer. Your eyes will thank you.
