    或已开始近视

    右眼,很明显。上星期有两天更是模糊得很,单用右眼看,前方的东西似蒙上一层很淡的薄雾。
    再早,一个月前,单位组织体检,双目视力测下来是4.8和4.6,左起。
    右眼视力为何差些?联想到大概一年前,为了阻击网前球,曾硬生生地被羽毛球头击中,当时剧痛,难受持续了好几天,点了眼药水,没看医生。
    幼年刚开始学会看书时,每每将双眼凑得离书本很近,家人邻居亲朋见此状无不以将来会近视警告我。
    没引起重视,近距离看书的习惯逐渐养成(当然也非凑得很近,只是与标准有些距离)。另一方面,是到了初中毕业时,诸多无论学习刻苦整日看书者或调皮捣蛋不近课本者一一近视,我似与近视无缘,近视亦似与看书之类的用眼习惯无关。更有理论依据:如遗传相关,如某种维生素的缺乏等等。
    毕业近十年,整日痴坐于电脑前工作也已八九载。如今的苦果,是不是应验了积沙成塔的古训呢?或者我体内某种维生素缺乏?别自我安慰了,许前者居多。

    身边的喻材(四)
    点眼药水,个人经验,正确的手势为:一手撑开眼皮,另一手的大拇指和食指握药瓶,中指发力将药水挤出。
    之前经验不足时,没有去发挥中指的作用,仅靠大拇指和食指,要不半天挤不出来,要不没能对准眼球滴下。
    在这个案例中,大拇指和食指起了稳定方向的作用,如果同时还想让他们发力,则会牺牲方向的准确度。
    要充分调动各个手指,分工明确、各尽所能。

    身边的喻材(五)
    自从视力明显下降后,远方就变得模糊,这时安慰自己的地方就是电梯厢中或封闭的小房间里。
    因为看不到远方,视力所及,一切都是清晰的。
    人无远虑,必有近忧。眼若近视,就别远眺。
