Cross-sectional study assesses eye strain symptoms and visual-evoked potentials among young adults with different screen times, suggesting a need for awareness.
Key Points
To evaluate how different screen time durations affect visual-evoked potential parameters and eye strain symptoms in young adults.
Cross-sectional comparative study design
Sixty participants aged 18-25 divided into three groups based on screen time
Monocular recording of pattern reversal visual-evoked potentials
Latencies of VEP components (N75, P100, N145) were measured
Statistical analysis with significance set at P < 0.05
Significant increase in P100 latency with prolonged screen time
Mean P100 latency increased from 109.68 ms in Group A to 122.13 ms in Group C (P = 0.0044)
N145 latency showed a non-significant upward trend
88.3% of participants reported eye strain symptoms
Symptomatic individuals had significantly longer screen time (P = 0.0071)
