If you look at anything continuously for a long time, such as reading a book or watching TV, you may experience eye strain. The same could happen if you look at a laptop’s screen for a long time.
Just looking at the screen is not harmful to your eyes. Eye strain is caused by looking at the screen without a rest for long periods of time. The good news is that the LCD (Liquid Crystal Display) screen of a laptop is easier on the eyes than the CRT (Cathode Ray Tube) screens of older desktop computers.
Teachers would not customarily look at a laptop screen for many hours on end and it is therefore unlikely that they would develop eye strain. If your eyes are more sensitive than that of the average person, you may have to take precautions to protect them. In some severe cases special spectacles could be prescribed by your optician.
Consider a few common sense measures that could alleviate the little bit of eye strain that you may have to endure.
Since eye strain is caused by long, uninterrupted periods of staring at the screen, take frequent breaks. Get up and walk around – not only will it rest your eyes, but it will also be good for the rest of your body.
Blink more frequently – it rewets the eyes and prevents dryness and irritation. If blinking is not sufficient, try eye drops to relieve itchy or scratchy eyes.
Adjust the lighting in the room until you feel comfortable. This may require that you draw the curtains if there is a glare, or install an additional light if the environment is too dark. Experiment with different light sources and settings until you are satisfied.
The brightness and contrast of your computer screen can be adjusted and it is suggested that you play around with these settings until you find a combination that is just right for you.
Change the position of the laptop so that the screen is a comfortable distance from your eyes. You will be surprised at the difference that it could make if you move the laptop a few centimetres further or closer to you.
Anti-glare screen filters are useful when you have to work in an area where you can not change the environment.
These suggestions are easy to follow and do not cost you anything.
Look after your eyes – you and your laptop will need them for many years.
