Few days ago, I suffer of super itchiness of my eyes for excessive staring at the computer screen, coding of tiger look style to avoid errors. I thought I will go blind. But reading some articles, computer didn't do something wrong with my eyes but the surrounding like lights and air. I will quote this for you;

Can A Computer Screen Damage My Eye? Twenty years ago, few offices workers used computers, let alone had computers. However with the dramatic increase in home and office computer use,  complaints of eye fatigue and discomfort are commonplace. Many people assume increased computer use is the source of these complaints. But extensive testing in government and private laboratories has not produced scientific evidence that computer monitors will harm your eyes. Research has established that computer monitors emit little or no hazardous radiation, such as x-ray, or non-ionizing radiation, such as ultraviolet rays. While computers have no known harmful effects on eyesight, computer users do often complain of eye related symptoms such as eyestrain, headaches, fatigue, dry eyes, and difficulty focusing, These symptoms (Computer Vision Syndrome - CVS) however are caused not by the computer screen itself but rather by the conditions surrounding the computer screen, such as poor lighting or improper placement of computer equipment and computer furniture. In some instances, a pre-existing eye problem may be the cause.

Until recently I had a problem of itchiness, redness and irritation in my eyes. Normally i confronted with this problem whenever i went my home since i spend most of my time in front the television to watch my favorite movies and at the other times when i tried to read continuously or while using computer. Then I consulted an ophthalmologist for an eye examination and she said it is nothing but Dry eye syndrome. I really got stuck with these heavy wordings and by seeing my situation doctor said it causes due to excessive strain on eyes. When i start reading or using computer, it stretches sometimes more than 4 hrs. While concentrating on a screen or a book, the eye tends to blink less and this results in drying up of the tears which are the natural lubricant lining the eye’s surface. This may lead to the non production of tears in the eyes. Dry eye syndrome is also called Computer vision syndrome. What are the symptoms of Dry eye syndrome?

• The major symptoms related with dry eye syndrome are:
• Redness and irritation
• Itchiness and pain in the eyes
• Discharge and watery eyes
• Feeling of tiredness in the eyes and strain on the vision
• Blurring of vision

How can we get rid off the problem of dry eyes? Prevention is better than cure. So we can take few steps to prevent the situation like:

• After working or reading for 20-30 minutes at a stretch, we should look away from the screen or page and consciously blink which will  lubricates the eye surface by allowing the resurfacing of the tear film.
• We can read in good light and choose correct font size and colors with good contrast and visibility to minimize the eye strain
• Avoid exposure to dust
• Avoid direct blast from AC or fan
• Place the laptop screen at a comfortable level
• Avoid excessive exposure to dust and pollution
• Washing eyes with tender coconut water (my natural home remedy for dry eye syndrome)

What is the treatment available for Dry eye syndrome or Computer vision Syndrome?

• Better to consult an ophthalmologist rather than doing self treatment for an eye examination.
• Sometimes there may be refractive error, due to incorrect spectacle number which could be adding to the eye strain, can be sorted out by wearing a correction glasses especially while working on the computer.
• We can use lubricating eye drops.
• The best treatment is to keep on blinking to get rid off dry eyes.
