Computer Eye Strain
Computer Eye Strain can occur anytime you spend a long period of time looking at the same thing. Some people strain their eyes reading a book, while others feel eyestrain after they spend hours staring at a computer screen.
The symptoms of eye strain can include a headache and vision that is blurred or fuzzy around the edges. Strained eyes feel dry, watery, scratchy, red, sore, or tired. They may sting or burn, causing you to close them frequently.
In order to reduce computer eye strain, keep your computer monitor approximately at arm's length away from you. This is the distance at which the monitor is meant to be seen; any closer or further can be harder on your eyes.
Your monitor should be at eye level, rather than too high or too low, which forces your eyes to look at the screen at an angle to which they are not accustomed. Keep the screen clean and remove light sources that are causing glare.
Dirt or the glare of a bright light can be distracting for your eyes as they try to focus on the content of the screen. If you feel eye strain frequently after sitting at your computer, undergo an eye exam to ensure that you are wearing the appropriate Computer eyeglasses or contact lenses that are designed for computer use.These glasses or contact lenses can help to reduce symptoms of computer eye strain.
If you spend long periods of time at the computer, eye strain is nearly inevitable. However, there are some things that you can do to alleviate the symptoms. If you feel your eyes straining as you look at the computer screen, there are exercises you can do to reduce the effects.
First, concentrate on blinking. As you look at a screen, you tend to blink less frequently. Blinking wets the eye surface. If you do not blink frequently enough, your eyes can dry out quickly and become uncomfortable, especially if you are using your computer in an office, an environment which tends to have very dry air. Slowly open and close your eyes a dozen times every 15 to 20 minutes in order to keep your eyes lubricated.
Rest your eyes periodically throughout the day by closing them for a few minutes or by getting up and walking to another area, preferably one where your eyes will be looking at objects at a distance of at least 20 feet, rather than close-up like a computer screen.
As your vision shifts from close-up to distance viewing or vice versa, your eyes are forced to refocus. When you do look away from the screen, you may experience focusing fatigue, which can cause blurry vision or difficulty focusing for a few seconds as your eyes adjust to the new view. Concentrate on an object in the distance to help your eye muscles relax.
Scan exercises can also help to relax sore eyes. Focus on an object in the room other than your computer. Then, without stopping, slowly move your eyes around the room. Concentrate on focusing on each object that you see. Continue to let your eyes scan for 2 minutes as you focus on breathing slowly.
Resting your eyes will usually cure computer eye strain, but it can be uncomfortable and make it difficult to concentrate on the screen. By adjusting your computer monitor and taking frequent breaks to exercise your eyes, you can prevent your eyes from being strained as you use the computer.
