方法：对珠海市3所高校1 218名在校本科生进行问卷调查，了解视屏终端暴露时间、眼部症状评分，对不同年级学生视屏终端暴露时间及不同暴露强度人群眼部症状评分进行比较，并对视屏终端暴露时间与眼部症状评分进行相关性分析。

结果：3所高校本科生视屏终端暴露时间平均为3.72±2.17h，随着年级的增长，视屏终端暴露时间延长，暴露时间越长，眼部症状越明显，视屏终端相关眼病与视屏终端暴露时间具有正相关性。

结论：长时间视屏终端暴露不利于眼健康。应加强对大学生的眼保健教育，避免或减少视屏终端暴露带来的健康损失。

METHODS: By use of questionnaire, a survey was carried out in 1218 undergraduate students from 3 universities in Zhuhai to find out their VDT exposure time and their eye symptoms. VDT exposure time at different grades and ocular symptom scores in different exposure intensity crowd were compared, the relationship between VDT exposure time and ocular symptoms were investigated.

RESULTS: On average, VDT exposure time in all students of the three universities was 3.72±2.17h, the mean exposure time increased with grade. And the ocular symptoms scores increased with exposure time, VDT has a positive correlation with VDT exposure time.

CONCLUSION: Long-time exposure to VDT is harmful to visual health, eye health education should be strengthened to avoid or reduce the health damages caused by VDT exposure.
