Overview

"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.

Individuals will be randomly assigned to either an experimental group (group A) receiving OBT with routine rehabilitation CVS management 20-20-20 rule, blue light-blocking glasses, and polyvinyl alcohol eye drops or a control group (group B) receiving only routine rehabilitation, including the 20-20-20 rule, blue light-blocking glasses, and polyvinyl alcohol eye drops. OBT consisted of structured blinking exercises performed thrice daily for three months. Objective outcomes, including tear film parameters and visual function using subjective Computer Vision Syndrome Questionnaire (CVS-Q) shall be evaluated. The collected data will be analysed by using SPSS."

"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."
