What is Computer vision Syndrome?
Computer Vision Syndrome (CVS) is a complex of eye and vision issues associated with
prolonged computer usage. It arises from continuously focusing the eyes on a computer
display for an extended period, leading to symptoms collectively known as CVS. These
symptoms can include eye strain, headaches, blurred vision, and dry eyes. Chronic exposure
to computer screens may contribute to the development of CVS. Studies suggest that 70-80%
of individuals who spend more than 3 hours a day on computers experience some form of
Computer Vision Syndrome.
Does only the Computers?
- Laptop
- Television
- Smartphones
- Tablets
- Any Other visual aid.
Symptoms of Computer vision Syndrome include-
Eye strain: Eyes may feel tired or sore.
Headache: Prolonged Computer use can lead to headaches.
Blurred vision: Vision may become blurred during or after Computer use.
Dry eyes: Reduced blinking while Staring at screens Can lead to dry and irritated eyes.
Neck and shoulder: Poor posture and screen Pain positioning may Cause discomfort pain.
Several factors contribute to the development of Computer vision Syndrome-
Screen glare and reflections: Glare and reflections on screens Can Contribute to eye strain.
Improper lighting: Poor lighting in the working environment Can Stain the eyes.
Screen distance and angle: Viewing screens at incorrect distances or angles can contribute to discomfort.
Uncollected vision problems: Existing vision problems, like uncorrected farsightedness or astigmatism, can worsen with prolonged screen uses.
Steps to reduce Symptoms-
Get a Comprehensive eye examination- At least once in a year by an Ophthalmologist.
Use Proper Lighting-
Lighting should not be very bright or dark.
Position your Screen So that windows are to the Sides.
Minimize glare-
Install an anti-glare Screen on your monitor.
If you are using glasses use ARC as it reduces glare by minimizing the front and back surface of your eyeglasses.
Adjust your computer display settings:
Keep brightness low and Contrast high Letters of reasonable front size.
Blink and Rest:
Blink rate decreases to as low as 6-8 blinks/minute focusing On the Computer Screen.
Consciously blink:
The normal blink rate is 16-20 per minute.
Exercise your eyes:
Focusing fatigue: To reduce follow the 20/20/20 rule (every 20 minutes look at an object 20 feet away for 20 Seconds.)
This relaxes focusing muscles and reduces fatigue.
Take frequent breaks:
To reduce the risk of neck, back, and Shoulder pain.
Tips to reduce risk of Computer eye strain:
* Sit with head & neck in line with the torso, not bent down & hit back.
* Avoid viewing the screen with your head turned or back twisted.
* Keep elbows close to the body.
* Pick a chair with lower back support cushioned seats, and a contoured and front edge.
* Keep mouse Close 40 keyboard.
* Position the monitor So that the top of the screen is just above eye level.
* Keep monitor Close enough to read text without Struggling.
* Keep print documents at some height and distance display.
Frequently Asked Questions(FAQs)
CVS is caused by prolonged use of digital devices that require intense focus and can lead to eye fatigue. Factors such as poor lighting, screen glare, and improper viewing distances can contribute to CVS.
While CVS itself is temporary and does not cause permanent damage, long-term, untreated symptoms can contribute to eye strain and discomfort. Addressing symptoms promptly helps prevent potential issues.
People who spend prolonged periods on digital devices, including students, office workers, and individuals with existing vision problems, may be more prone to CVS. However, anyone who uses screens extensively can be affected.
Prescription glasses or special computer glasses with anti-reflective coatings may be recommended by eye care professionals to reduce glare and alleviate CVS symptoms.
Poor lighting, either too bright or too dim, can contribute to CVS. Optimal lighting should minimize glare on the screen and provide a comfortable environment for extended computer use.
While there’s ongoing research, prolonged exposure to blue light emitted by screens may contribute to eye strain. Blue light filters or computer glasses with blue light protection can be considered. If you suspect you have Computer Vision Syndrome or are experiencing symptoms, contact us now.
