subject: Save Your Eyesight At The Computer [print this page] Your computer plays a major role in deteriorating your eyesight. For example if you work for long hours in front of the computer your eyes might get damaged. Excessive computer use can cause eyestrain which might in turn destroy your vision. Focusing at the computer screen for long time might cause your eye muscles to become flexible and weaken your eyesight. This focus is one of the main causes of stress. It has been scientifically proved that you blink almost half as you would do under normal conditions and they even stop breathing as much as they should. It has been also seen that there can be poor circulation of oxygen and nutrition because of the poor position of your body.
Eyestrains can even force you to go for a pair of reading glasses after the age of 40 years. Various exercises can prevent the advent of presbyopia at an early age. Reading glasses are not a very good option for computer work and can cause headaches and backaches.
But can save yourself from these troubles by following these simple steps:
There are seven body positions you should follow. Your line of sight should be 6 inches above the computer screen, the computer screen should be a distance of 18-24 inches from your eyes, your knees should be slightly below hips, your legs should not be crossed, shoulders should be down and relaxed, your wrist should be a bit below your elbow and your fingers should be below your wrist.
If your desk is at a higher position and your shoulder cannot be stretched then it is better to keep the keyboard on your lap. You should take breaks for 3 to 5 minutes and concentrate on things apart from your computer screen. Place a mirror above your computer screen and then focus on images reflected behind you and then again focus on your screen for a number of times. You can also use the double sight therapy in which you have to hold your finger 4-5 inches from your nose and then concentrate on an image at a distance. You will see two fingers and then again refocus on the finger and you see two objects at a distance.
Most of the time when you are looking at your computer screen then your peripheral vision is blocked. This is why you should practice peripheral vision awareness program where you have to do a mental exercise to see what is above, below or side of your computer screen. A few signs of eyestrain which can make you tensed is that after looking at the computer screen for a long time suddenly the screen goes out of focus. Other signs can be headache, dry eyes, fatigue, your screen getting blurry and so on. Thus you should drink a lot of water, fresh berries and green vegetables.
