Computer vision syndrome (CVS) is a group of eye related problems and other issues that are induced from the overall stress incurred from the use of computer/ digital devices. CVS is not restricted to the eye alone but extends to all problems that arise from too much use of the computer and other digital devices like our phones, laptops, tablets and desktops. It is also called Digital Eye Strain and can affect all age groups exposed to the use of computer.
Symptoms of Computer Vision Syndrome
Here are some of the things that one is likely to experience if one suffers from CVS:
- Blurry vision
- Headache
- Eye aches
- Eye strain and fatigue
- Eye irritation and a feeling of dryness
- Neck pain
- Lower back pain
Prevalence and Causes of Computer Vision Syndrome
- Glare from computer: varying contrast from text/ objects viewed on our computer device can readily cause discomfort in the eye.
- Text type and font size: very small font sizes tend to cause more pressure to be exerted during screen time and can ultimately lead to eye strain and headache.
- Poor sitting posture: a working arrangement where one has to look up and down while alternating from the screen to a working material on the table and vice versa, is enough to cause neck strain and back aches.
- Studies in the past have proven that the blinking rate of the eyes is less than normal among computer users, this can allow dry eye to set in and cause eye irritation.
- Presence of uncorrected refractive error: not using a corrective lens when you need one or using a wrong prescription is expected to cause eye strain and fatigue when working on your computer.
- People around the age of 40 years: Naturally, a condition called presbyopia (difficulty reading at near 40yrs and above) will make any computer user that is within this age group and is not aiding their vision more likely to experience CVS.
