在当前的IT时代,不可否认的是,每个人的日常生活或多或少都在使用计算机或智能手机,这使每个人都警惕长时间使用计算机后会出现的问题,并且计算机视觉综合症是一种越来越常见的新疾病,其特征通常是发红,灼热,水汪汪的眼睛,水汪汪的眼睛,间歇性视力模糊。或发生暂时性近视它还具有慢性颈部疼痛。由于长时间坐在同一位置

那么使用计算机或智能手机的危险会导致失明吗?答案是不。”

如您所知,让所有人担心无法使用计算机和智能手机的原因可能是紫外线和蓝光的问题,所以让我们首先了解紫外线。

紫外线由太阳产生,其中含有UVA,UVB和UVC,UVC受地球臭氧的保护,而UVA和UVB则渗透到我们的星球中。但是进入视网膜的机会很小。这是因为UVA和UVB射线被99%的鞭子吸收,而仅下降到视网膜的1%,而不是来自计算机或智能手机。

蓝光(或称为蓝光)是在380-500 nm处具有短波长的光,从而使其大大分散了彩色光。从而造成眼睛疲劳视力轻松但是,蓝光不仅是罪魁祸首。这种灯的好处是刺激身体清醒阻挡光线的使用会影响身体的睡眠和唤醒系统。蓝光通常可以从计算机和智能手机的灯的阳光中找到,但是蓝光不会使用户蒙蔽。只有长时间使用计算机或智能手机时,它才会使用户感到不舒服。

曾经有人说过在黑暗中使用手机会导致黄斑变性或视网膜脱离,这不是很正确。由于可靠的研究蓝光与黄斑变性的发展之间的关系尚未建立。因为这种疾病是由多种因素引起的疾病。不仅仅是蓝色的光。

总之,用手使用计算机或智能手机不会引起失明。但这比开灯玩起来会带来更多的不适。因为他必须比平时更专注而且眼睛反射的光比平时多引起眼睛不适造成更多的眼睛疲劳使用这些设备的症状是偶发性症状。休息和停止使用时会像以前一样恢复正常
