Your computer monitor and your eyesight

With rising numbers of people using computers a definite increase in the numbers of people with tired eyes and eyestrain has occurred. There is no scientific link between using computers and permanent eye damage, however you do not need a scientist to prove the fact that using a monitor for any great length of time results in tired, red, and sometimes dry eyes.

There is also something called Computer vision syndrome, which is a common eye condition amongst computer screen users. Symptoms can range from tired eyes to blurred vision. If you do experience any of the following symptoms you could have computer vision syndrome. If you find it difficult to focus on distant objects after using a computer, you have headaches, eyestrain or dry eyes you need to take extra care when using a monitor to avoid getting computer vision syndrome. It is also best to visit your optician for an eye test to rule out anything more serious.

Here are some tips to help with tired eyes:

• Take breaks. Focusing on the screen for long periods can lead to computer vision syndrome so it is important to take regular breaks. You should rest your eyes every 20 minutes by looking away from the screen. You can also use the 10-10-10 rule, every ten minutes focus on something at least 10 feet away for at least 10 seconds.
• Adjust your monitor settings and position. You should adjust your computer so that the monitor settings are comfortable for you. The brightness and contrast can be adjusted so that you are not straining your eyes. Try using a larger font size or using the zoom option on the page layout to make it easier on your eyes. The screen should also be kept clean using special wipes. Your health and safety manager at work will be able to help you ensure the screen is positioned correctly. The screen should be at least at arms lenght away from you, and also new research has discovered that the verticle centre of the monitor should be at eye level.
• Check the lighting around the computer. There should not be any bright sunlight reflecting onto your screen. Using an anti-glare screen which is fixed onto your monitor is a good idea to reduce any glare and will block any reflections.
• Blink frequently. Remember to blink at regular intervals. When you are concentrating for a long time at a computer your blink rate slows down. Some people also find that they get dry eyes when using computers. This is one of the symptoms of computer vision syndrome but it can be relieved by using eye drops. Ask your optician for advice if you get dry eyes. Those who wear contact lenses may be more prone to dry eye.
• Have regular eye tests. Experts recommend that adults should have an eye test at least every two years. An eye test will check your eyesight and will also look for signs of eye disease. Other health problems may also be detected during an eye test.

If you use computers for work you may be entitled to a free eye test, paid for by your employer. Under European legislation employees who use VDUs are entitled to an eye test when they begin using VDUs and at regular intervals throughout their employment. If you experience eye problems which may be a result of using VDUs then you will be entitled to a free eye test. If you then need to wear glasses your employer must pay for a basic pair of glasses or you can pay the difference for a pair of your choice.
