Abstract

BACKGROUND

This population-based, cross-sectional study aimed to assess the correlation between near vision and smartphone usage among people aged ≥50 years in China.

METHODS

This study was performed on the ocular health status of residents in Fujian Province, Southeast China. People aged ≥50 years were recruited. The main contents of the survey for the residents included socioeconomic status, uncorrected near visual acuity (UNVA), refractive state, as well as a questionnaire about smartphone usage and visual quality.

RESULTS

Smartphone adoption accounted for 67.7% (4,702 individuals) of the total population, which decreased with age in the elderly. Smartphone owners had a higher average UNVA of 0.31±0.18 than non-smartphone owners (0.23±0.14), and the difference was statistically significant (P<0.001). Individuals who used smartphones for a long time usually had better UNVA (Pearson correlation coefficient 0.144, P<0.001). The rates of complaints of distance vision loss, near vision loss, ocular surface discomfort in smartphone users were significantly higher than that of non-users (P<0.001). Also, smartphone adoption and visual quality differed between urban and rural respondents.

CONCLUSIONS

Smartphone adoption and usage time in the elderly significantly decreased with age and UNVA, and the performance of visual impairment was not consistent in urban and rural areas.

摘要

背景

本研究采用基于人群的横断面研究，旨在评估中国≥50 岁人群近视力与智能手机使用之间的相关性。

方法

本研究以中国东南部福建省居民的眼部健康状况为研究对象。纳入年龄≥50 岁的人群。调查的主要内容包括社会经济状况、未矫正近视力（UNVA）、屈光状态以及关于智能手机使用和视觉质量的问卷调查。

结果

智能手机的使用率为 67.7%（4702 人），在老年人中随年龄增长而降低。智能手机使用者的平均 UNVA 为 0.31±0.18，高于非智能手机使用者（0.23±0.14），差异具有统计学意义（P<0.001）。使用智能手机时间较长的个体通常具有更好的 UNVA（Pearson 相关系数 0.144，P<0.001）。与非使用者相比，智能手机使用者抱怨远距离视力下降、近距离视力下降和眼表面不适的发生率显著更高（P<0.001）。此外，智能手机的使用和视觉质量在城乡受访者之间存在差异。
