vision, neck pain, redness in the eyes, fatigue, eye strain, dry eyes, irritated eyes, double vision, polyopia, and difficulty in refocusing the eyes- these are the common problem that young and adults are facing today. Kids are severely in the grip of common vision syndrome, a complex vision problem that props up after the prolonged use of Computer, Ipad and electronic gadgets.
The disorder are ignored most of the time by reluctant gadget freaks. They neglect minor pains thinking it is caused by stress or work pressure but the underlying problem which has grown-up rapidly is the Computer Vision Syndrome
Eyes are the most delicate part of a human body. Staring at brightly-lit computer screens for prolonged hours with constant attention may adversely affect vision of millions. Medicos indicate CVS is caused by our eyes and brain reacting differently to characters on the screen than they do to printed characters.
We sit for hours in front of computer and screens, which is the most common cause of this ailment.
Blinking is very important when working on a computer as it rewets the eyes, which avoids dryness and irritation. When working on a computer, people blink less frequently and lower blinking rates cause eye moisture to evaporate thus leading to dryness.
According to the National Institute of Occupational Safety and Health, computer vision syndrome affects some 90% of the people who spend three hours or more a day at a computer.
Sr. Optometrist, P singh, says, “People are less aware and neglecting their eyes results in eye problems. First, a mandatory check is important after a child turns 10-12 years old because undetected errors can lead to permanent defect in the eyes. Post 40, people should go for eye check-ups regularly. Factually, children during the age of 7-14 yrs are more prone to this ailment. 20- 25 percent are kids suffering from myopia, which later on turns into expegatism( use of cylindrical power in lens)
He further adds, “We are seeing an increase in eye problems due to high usage of computers and laptops, but one cannot turn away from them either. So, one should use eye drops which act as artificial tears and lubricants and help avoid dryness.” People who face eye problems, often complain of burning sensation, irritation and the presence of a foreign body and strain.Precautions:
One can use proper lighting, minimise the glaze and brightness of the computer screens and the quality of monitor display to avoid unnecessary strain on the eyes. Also changing one’s workstation can help minimise symptoms. This can be done by placing the monitor directly in front of you and it should be about 20 to 26 inches away from you.
Also, make sure the monitor is not too high. Experts also recommends that the center of the screen should be four to nine inches below your straight-ahead gaze. If you reposition your chair, keep in mind that your arms should be parallel to the floor when you type, and your feet should be flat on the floor or on a footstool.
Adjust the contrast and brightness at moderate levels and reduce the screen glare. Blink 10 times by closing your eyes as if falling asleep (very slowly). This will help rewet your eyes, Do this after every 30 minutes and take frequent breaks and exercise your eyes whenever possible.Blurred Vision:
Decreased focusing capability is mitigated by wearing a small plus-powered (+1.00 to +1.50) over-the-counter pair of eyeglasses. Wearing these eyeglasses helps such patients regain their ability to focus on near objects. People who are engaged in other occupations—such as tailors engaged in embroidery—can experience similar symptoms and can be helped by these glasses.Preventions:
Stop periodically to blink, stretch and look away from the computer screen.
Sit approximately 24 inches away from the screen
Use of anti reflective filter would be a good choice for CRT monitors
Keep an adequate text size so that you can comfortably view
Check your posture from time to time to reduce neck, shoulder and wrist pains.
After every 20 minutes of work look away from the screen for at least 20 seconds.
Use artificial tears to lubricate your eyes periodically, prefer the use of preservative free tears.
Do eye exercises like Close eyelids and roll the eyes behind your closed lids once clockwise & once anti clockwise
