Effects Of Optimized Blinking Training on Visual Function and Tear Film Parameters in Individuals With CVS

"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.

About this study

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."

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Individuals aged 18-40 years who work on computers or digital devices for at least 3 to 6 hours daily.
  • Both Male and Female.
  • Individuals who could undergo a complete ocular examination.
  • Presence of symptoms consistent with digital eye strain.
  • Presented with eye complaints such as eye fatigue, burning, irritation, redness, and blurred vision due to long-term computer or digital screen use.
  • Symptoms worsened during exposure to digital screen light.

Exclusion criteria

  • Use of medications that might influence tear production or ocular surface status (e.g., antihistamines, antidepressants).
  • Diagnosed neurological or systemic conditions that impact vision or blink patterns (e.g., Parkinson's disease, multiple sclerosis).
  • Individual's with a history of ocular surface diseases such as conjunctivitis or keratitis.
  • History of any psychiatric diagnosis."

Treatment and study plan

Grouyp 1 (without blinking exercises).

Diagnostic Test

Group B (Control Group) The control group will continue receiving only the routine rehabilitation (without blinking exercises). Routine rehabilitation included the 20-20-20 rule, blue light-blocking glasses, and polyvinyl alcohol eye drops.

EXP group (Routine CVS treatment)

Combination Product

"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."

Primary outcomes

  1. Computer Vision Syndrome (CVS-Q)

    Time frame: 12 Months

    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
