Dry Eye
IT IS AN EYE CONDITION OCCURING DUE TO REDUCED PRODUCTION OF TEARS OR EVAPORATION OF TEARS OR DUE TO EXCESSIVE SCREEN TIME
CAUSES OF CVS(COMPUTER VISION SYNDROME)
We use DIGITAL SCREENS for work, study & entertainment. Normally our eyes blink 16 to 20 times per minute, but studies have revealed that while using computers the number of blinking is reduced to 6 to 8 times per minute. So as we keep our eyes wide open looking at the screen, it dries up the tear film and causes dry eyes.
When we read something on the computer, the letters on the screen have no well-defined edges and lack contrast, unlike the printed letters. It creates discomfort in one’s eyes to stay focused on the screen. But repeated refocusing on the characters lead to eye fatigue, eye strain, burning, CVS pink eye AC & poor lighting can further worsen the issues of CVS.
Apart from these, other reasons for this eye condition are:
Poor sitting posture in front of the computer
Poor lights producing reflections or glares, abnormally dim or bright images
Failing to blink often and moisture the eye surface
Using improper eye-glasses while working on the computer
Colour of walls in the room you work
Anti-reflective coating
A direct blow of air or air-conditioner on the eyes
SIGNS AND SYMPTOMS OF CVS
Heaviness on the eyes
Cloudy vision
Eye Strain while using digital screen
Frequent headache while working
Pain in the neck and shoulders while working
Double eyesight
Irritation in the eyes
A tendency to vomit while focusing
Dizziness while sitting in front of the computer etc.
WAYS TO PREVENT CVS
Screen placed at a lower angle from your eyes, slanting and 28cms from your eye
Turn down your lighting & use glare filters over your computer screen.
Place a document holder next to your computer screen. Keep it close enough so you don’t have to swing your head back and forth or repeatedly change your focus.
Fumes or low humidity worsen a dry eye disease.
Blink every time you clin enter till it becomes a habit
Follow a rule of looking away every 20 mins beyond 20 feet and blink 20 times.
Take breaks from looking at the screen frequently.
Ask your doctor if you can use artificial tears and use it to lubricate your eyes whenever needed.
