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.

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.
