一般来说,远视眼很少误当作近视而配凹透镜的。但对于调节力极为丰富的幼儿,这种错误则容易出现。下面介绍一病例: 林×,女,7岁,配戴近视镜3个月,因视力下降来我院验光。自诉带镜有头晕等不适感,看书写字时眼胀痛。经检测,原戴镜为双眼-1.50DS,查裸眼视力右0.5,左0.4,矫正视力布0.6,左0.4。小瞳检影发现:初始影动为逆动,加上-1.50DS镜片能够中和。但让其放松且注视5m以外处的物体时,呈现出顺动影,可用凸透镜
In general, hyperopia is rarely mistaken for myopia and concave lens. But for children with very rich conditioning ability, this mistake is easy to appear. The following describes a case: Lin ×, female, 7 years old, wearing myopia for 3 months, due to decreased visual acuity to our hospital.

Small pupil retinoscopy found that: the initial film movement is inverse kinematics, coupled with -1.50DS lens can be neutralized. However, let it relax and watch objects at 5m away, showing a smooth moving image can be convex lens
