1、避免慢性光损伤从娃娃防起避免慢性光损伤从娃娃防起“看手机导致眼睛失明” ，这种说法有点夸张，大可不必谈虎色变。但是此类产品对眼睛的 光损害是肯定的。光损伤有急性和慢性之分，短期的极强烈的光线可导致角膜、视网膜尤其是黄斑区的 损伤，表现为刺痛、畏光、流泪、视力骤然下降至失明。微信里说，在黑暗里连续看半小 时的手机，就会引起黄斑的损害而失明，一般来说这是不可能的。急性光损伤如果损害不 深，及时治疗多可恢复。其实，沉迷于手机、iPad 引起的眼睛的损害，常造成视疲劳、干眼、屈光度变化等， 尤其是慢性的视功能损害。慢性的视功能损伤源于经年累月的较强的光 照，可导致晶体混 浊、眼底视网膜、黄斑区的感光细
2、胞水肿变性坏死而视力下降乃至失明。而慢性光损伤由 于发展缓慢，症状容易忽略，其最大的危害是所造成的视 功能损害是不可逆的。慢性光损伤对外眼、内眼都可能造成损害。外眼病如睑缘炎、慢性结膜炎、翼状胬肉、 浅层角膜炎等。对眼内的损伤包括长期光刺激会导致晶体混浊即白内障。对视网膜黄斑区 的损害包括水肿、出血、新生血管等。老年性黄斑变性的发病原因之一，就包括长期的光 刺激。慢性光损害可以影响到各个年龄段。要防治慢性光损害，首先要避免眼睛长时间对着 光源。由于较强的光线、较长时间的刺激眼睛，都可能造成光损害，因此，应避免直接直 视一切强光源，对日常使用的电脑、电视、手机的屏幕亮度要调低、光线要柔和。而要避
3、免慢性光损伤要从娃娃开始做好预防。2 岁内的婴幼儿最好别让其看电视、玩 手机。有些家长为避免小孩哭闹，把手机、iPad 任由宝贝玩，长此以往， 对小孩的眼睛的 损害是不可估量的。特别是婴幼儿时期，由于晶状体、角膜清澈透明，光线容易直接透到 眼底，而且视网膜比较娇嫩，这是眼睛最容易产生光损伤的 时期。另一方面，婴幼儿对光 亮的东西比较好奇，喜爱追逐、凝视光源，更增加了光损伤的机会。可以说，年龄愈小的 婴幼儿眼睛受强光损害的机会愈大。因而具有 光线刺激的玩具，千万不要长时间给宝宝玩。值得提醒的是，有些人喜欢在黑暗的环境下长时间玩手机，这习惯非常不好。因为在 黑暗环境中加上精神集中关注，有青光眼素质
4、的人容易引起眼压升高而激发急性青光眼。不单是手机或 iPad，现在人们的工作、娱乐都离不开电脑等各种屏幕，由于专注于屏 幕，眨眼的次数少，眼泪对眼睛的润滑少了，久而久之可以引起眼睛干燥、发痒或灼热的 感觉。所以在面对屏幕时要有意识地多眨眼，使到眼睛表面尽量保持湿润，对缓解干眼的 症状有好处。特别是长期需要面对电脑工作的人，应该控制长期连续工作的时间，中间休息时可远 眺或滴滋润的眼药水。如果感到视力模糊、眼胀、眼干等不适，经过自行滴保健眼药水仍 收效不明显时，还需到医院眼科检查。“See mobile phones cause blindness“, this statement is a bi
