Eye Sight

Eyesight Weakness is a common problem of the day. Even tender aged school going children may also be seen using spectacles due to weak eyes. Few Days back I got my Eye Test Done and as was worried got the Number (Negative Effects of Modern Technology).Then I started searching the cause for Eyesight Weakness, though I knew that I spend lot of time in front of computer and this is the cause for it but i didn't knew what is called Computer Vision Syndrome until I was surfing about causes for eye weakness. Do you know about it? If not then Read on. 

First let’s know about the general causes of Eye Weakness- Heat and Weakness of brain is a main cause of weak eyesight. The morbid matter eliminating by means of Common Cold if suppressed by wrong treatment may also adversely effects the eyes. Beside this, long over and closely watching of TV, continuous reading in a powerful light, digestive disorder, unbalanced eating and living habits and deficiency of vitamin A in food are also responsible for weak eyesight. In maturity, excessive worry and consumption of alcohol also produce weakness of eyes. 

So now we know general causes of eyesight weakness so let’s see what is this Computer Vision Syndrome?

Computer Vision Syndrome, or CVS, is a direct consequence of spending too much time in front of a computer screen. 

What Causes Computer Vision Syndrome?

Computer eye strain and computer vision syndrome are caused by our eyes and brain reacting differently to characters on a computer screen than they do to printed characters. Our eyes have little problem focusing on printed material that has dense black characters with well-defined edges. But characters on a computer screen don't have the same degree of contrast and definition.

Words on a computer screen are created by combinations of tiny points of light (pixels), which are brightest at the center and diminish in intensity toward their edges. This makes it more difficult for our eyes to maintain focus on these images. Instead, our eyes want to drift to a reduced level of focusing called the "resting point of accommodation" or RPA.

Our eyes involuntarily move to the RPA and then strain to regain focus on the screen. This continuous flexing of the eyes' focusing muscles creates the fatigue and eye strain that commonly occur during and after computer use. 

What Are the Symptoms of Computer Vision Syndrome?

If you or your child spend more than two hours per day in front of a computer screen, it's likely you will experience some degree of computer vision syndrome. Symptoms of CVS include:

Headaches

Loss of focus

Burning eyes

Tired eyes

Double vision

Blurred vision

Neck and shoulder pain  

Will Glare Screens Prevent CVS?

Anti-glare filters for computer screens may increase comfort somewhat, but they will not solve all your computer vision problems. These filters only reduce glare from reflections on the computer screen and do not reduce the visual problems related to the constant refocusing of your eyes when you work at a computer. 

Will Wearing Computer Eyeglasses Make My Eyes Worse?

This is not true. In fact, wearing specially prescribed computer glasses when working at your computer may keep your eyes from getting worse by reducing excessive focusing demands on your eyes. This is particularly true for teenagers, whose eyes may be more susceptible to progressive nearsightedness from focusing fatigue. 

Will My Reading Glasses Work at the Computer?

Reading glasses are usually not the best solution for computer use. Eyeglasses prescribed for reading typically will optimize your vision at a distance of 14 to 16 inches from your eyes, which is considered the standard reading distance. But for the greatest comfort, your computer screen should be positioned farther away — at a distance of 20 to 24 inches from your eyes. For the best vision at this distance, a different eyeglass prescription is usually required. 

Some general home remedies which might be helpful to some (Dadi maa ke nuskeJ)

  Some Eye Exercise

1. Palming:- To rest and relax your eyes, sit comfortably in front of a table, resting your elbows on a stack of cushions high enough to bring your palms easily to your eyes without stooping forward or looking up. Close your eyes and cover them with your cupped palms to exclude light, avoiding pressure on the sockets. Breathe slowly and evenly, relaxing and imagining deep blackness. Begin by doing this for 10 minutes, two or three times a day.  
 
2. Swinging: - Relax and keep the eyes mobile. Stand up and focus on a distant point, swaying gently from side to side, repeat 100 times daily, blink your eyes as you sway. Blinking cleans and lubricates the eyes, which is especially important if you spend a lot of time in front of a computer.  
 
3. Color day: - You may be asked to have a 'color day.' Choose a color and look out for it throughout the day. When you see it, be aware of the color rather than the form. For example, if it's a red truck, experience the shade of red, not the truck.  
 
4. Sunning: - Try to do this once a day. It requires a sunny day, or a good desk lamp with an incandescent bulb. The exercise is simple. Close your eyes. Look directly at the sun through your closed eyes. While facing the sun, slowly rotate your head from side to side as far as you can. This gets the sunlight on the peripheral vision, and it helps bring more blood circulation to your neck. Do this for 3 to 5 minutes. It's amazing, even on a cold day, how warm the sun feels on your eyes.
