Abstract

Purpose: To evaluate the impact of gaming on ocular accommodative parameters.

Methods: A comparative and experimental study was conducted among non-orthoptic university students for a duration of six months from September 2023 to March 2024. After a half-hour of gaming, the subjects' accommodative parameters were examined and compared. The accommodative parameters before and after iPad gaming were compared.

Results: The study included 80 participants (mean age 22.96 ± 2.23 years; 50 males, 30 females). Post gaming near-point of accommodation decreased (right eye: 10.75D to 7.15D, p < 0.001), Negative Relative Accommodation (NRA) increased from 2.64 ± 0.23 DS to 2.92 ± 0.37 DS, whereas Positive Relative Accommodation (PRA) decreased from -2.46 ± 0.41 DS to -1.78 ± 0.31 DS. The Monocular Estimation Method (MEM) values showed accommodative lag (right eye: +0.46 ± 0.15 DS to +1.24 ± 0.26 DS, p < 0.001). Monocular Accommodative Facility (MAF) and Binocular Accommodative Facility (BAF) exhibited decrease in facility (MAF; right eye: 10.34 to 4.54 cpm, BAF: 10.65 to 4.90 cpm, p < 0.001).

Conclusion: This study shows 30 minutes of gaming using digital devices leads to decrease in accommodative parameters, potentially causing ocular fatigue and binocular vision anomalies in young individuals.

视觉显示单元对青壮年眼调节的影响。

目的：评价游戏对眼调节参数的影响。方法：于2023年9月至2024年3月对非正视大学生进行为期6个月的对比与实验研究。在半小时的游戏后，研究人员检查并比较了受试者的适应性参数。比较iPad游戏前后的调节参数。结果：共纳入80例受试者，平均年龄22.96±2.23岁；男性50人，女性30人)。游戏后近调节点下降（右眼：10.75D至7.15D, p < 0.001），负相对调节（NRA）从2.64±0.23 DS上升至2.92±0.37 DS，而正相对调节（PRA）从-2.46±0.41 DS下降至-1.78±0.31 DS。单眼估计法（Monocular Estimation Method， MEM）值显示调节滞后（右眼：+0.46±0.15 DS至+1.24±0.26 DS, p < 0.001）。单眼调节设施（MAF）和双目调节设施（BAF）的调节设施（MAF）呈下降趋势；右眼：10.34 ~ 4.54 cpm, BAF: 10.65 ~ 4.90 cpm, p < 0.001)。结论：这项研究表明，使用数字设备玩30分钟的游戏会导致适应性参数下降，可能导致年轻人眼疲劳和双眼视力异常。
