When you look at a computer screen you have to move your eyes – if you are reading it will be mostly from left to right but if you are doing something else such as gaming, your eyes will be all over the screen. When you combine this with the fact that they have to adjust to the brightness, focus and other factors that come with screens and you get computer vision syndrome. You will know that you have it because you have blurred vision, double vision, irritated dry, red eyes, headaches and sometimes neck pains. So what can you do to avoid all these things?
1. The glare from your computer screen is a big problem. The more glare your eyes have to deal with the more overworked they are. Glare gets worse as lights around you get brighter so you should make sure that there is little light around you as you use your computer screens. Avoid using it near windows and if the overhead lights are too bright get a dimmer. If the glare is in your office computer then you should get a special screen that reduces glare – they are quite cheap.
2. Arrange things in such a way that you don’t have to struggle to see your screen. The ideal distance between your eyes and the screen is between 20 and 28 inches from your screen. To avoid having to look up and down from any papers that you may be working on you should place a stand next to the screen so that you minimize the number of eye movements.
3. It is very important that you give your eyes a break every so often if you will be using a computer for a long time. Eye doctors recommend that if you work for about 20 minutes you should move your eyes from the screen for about 20 seconds and focus your eyes on something in the distance. Although it is hard to remember this, if you feel your eyes becoming dry you should blink a few times to lubricate them with tears. If the dryness is persistent you can see an eye doctor who will prescribe a lubricant.
4. Your computer comes with certain settings from the factory. You dint have to live with them – with a few tweaks you may find that your eyes are much more comfortable. Try adjusting to several different settings and see what you are most comfortable with. It is also important to ensure that you have the right font size – if the font is too small you will strain to read and if it is big your eyes have to work harder.
5. Find a text size that you can see from 20 inches away. The color on your screen also matters. Research has shown that blue hues strain the eyes more than oranges and reds. If you are using Windows you can adjust the settings in the control pane quite easily. For Mac, you should look in system preferences.
6. If you work on a computer all day in the office it is important that when you are at home you rest them. Avoid getting back on a screen when you get home. Instead, you can take a walk where you eyes get to focus on different things completely. This gives them time to rest for the next day.
7. If you use computers all the time it is very important that you see your optometrist at least once a year for an eye checkup. He will be able to detect and treat eye problems before they can become too serious. He may find that your eye problems can be resolved by issuing you with lenses or glasses. Whichever the case, if the optometrist recommends them make sure that you wear them each time you are working on your computer.
These tips should help you avoid or at least reduce computer vision syndrome.
