用凹透镜矫正近视已成为常规方法,但是否所有近视眼都要充分矫正呢?过去认为,低度者应充分矫正,中高度只作部分矫正。现在主张,对各种近视都要充分矫正。因为充分矫正后,不但能提高远视力,防止进行性近视的继续发展,还可防止处斜视。 低度和中度近视充分矫正后,不论看远还是看近,患者都乐于配戴。但有个别高度近视患者,由于戴了充分矫正的镜片,在看近处物体时,迫使患眼动用调节,(也就是高度近视眼在未戴镜前从未使用过的调节部分)所以对于年龄较大的患者,可产生比较明显的不适感,因此不得不从看远的镜片中减去-1.5D～2.0D或更多,以戴镜舒适能接受为原则。 近来,幼小动物实验证明,如果剥夺了正常的视觉
The use of concave lens correction of myopia has become a common method, but whether all myopia should be fully correct it? In the past that the low should be fully corrected, only partially corrected in height. Now advocate for all kinds of myopia should be fully corrected. Because fully corrected, not only can improve far vision, to prevent the progressive development of progressive myopia, but also to prevent strabismus. Low and moderate myopia after full correction, either look far or near, patients are willing to wear. However, some individuals with high myopia, due to wearing a fully corrected lens, in the near object, forcing the eye movement regulation, (that is, high myopia in the mirror before the use of the mirror has never been used before the adjustment part) so for the age Larger patients, can produce more obvious discomfort, so have to look away from the lens to subtract -1.5D ~ 2.0D or more, comfortable to wear glasses as the principle of comfort. Recently, young animal experiments show that if deprived of normal vision
