摘要
目的:了解长时间注视视频终端(video display terminal,VDT)对眼健康的影响,并提出预防对策。方法:对长时间连续注视VDT者视功能、屈光状态及眼进行检查,测定调节幅度、集合近点,并与很少或不操作VDT者的同样检查或测定情况进行对比。结果:长时间连续注视VDT者,其眼的健康比非注视VDT者更容易出现眼痛、眼胀、视物模糊、视力下降等视疲劳现象,并且随注视时间的延长,视疲劳的倾向更明显,调节幅度降低,集合近点远离。两组比较差异有统计学意义(P<0.05)。结论:长时间连续注视视频终端较阅读书本等界面更易对眼产生负面影响,应加强预防VDT性眼健康损害。
AIM ： To discuss the effect of chronically watching video display terminal （VDT） on eye health and to propose the prevention counter measures.
METHODS： The visual function, refractive status and eyes of persons, who chronically watched VDT, were tested. The accommodation amplitude and near point of convergence were measured. The results were compared with those seldom or did not watch VDT.
RESULTS： Compared with those seldom or did not watch VDT, the persons who chronically watched VDT were more easily presented ophthalmalgia, swelling, visual blurring, hypopsia and so on. The more watching VDT, the trend of asthenopia were more obvious following with decrease of accommodation amplitude and departing of near point of convergence. There was statistical significant between two groups （ P 〈 0.05）.
CONCLUSION： The results show that chronically watching VDT, reading book and other interfaces will produce negative influence on eyes. Therefore, we should pay more attention on prevention of eyes damage from VDT.
