Brief Summary

"Computer vision syndrome (CVS), refers to a range of eye and vision issues caused by extended use of computers, tablets, e-readers, and smartphones. Computer users experience visual symptoms, such as eyestrain, headaches, eye discomfort, dry eyes, double vision, and blurred vision, especially after long periods of looking at screens, whether up close or at a distance.

Conditions

Computer Vision Syndrome

Outcome Measures

Primary Outcomes (1)

• Computer Vision Syndrome (CVS-Q)

  The Computer Vision Syndrome Questionnaire (CVS-Q) assesses the frequency and intensity of 16 ocular and visual symptoms related to prolonged screen use, with a total score of 6 or more indicating CVS If the total score is ≥6 points, the individual is considered to suffer Computer Vision Syndrome

  12 Months

"Group A (Experimental Group): Individuals in the Experimental group will receive Routine CVS treatment with optimized blinking exercise. Routine rehabilitation includes the 20-20-20 rule, blue light-blocking glasses, and polyvinyl eye drops. The blinking exercise involved the individuals looking at an object 6 meters away for 5 seconds, followed by complete eyelid closure for 5 seconds. This cycle was repeated for 5 minutes, twice a day."
