近视、远视、散光能配戴眼镜进行矫正,这是人所共知的。其实,斜视、弱视等眼病,配戴眼镜也能起到矫正的作用。北京六○八厂厂长蔡登元同志说,患有斜视的儿童,可在四至五岁时,配戴三百度左右的老花镜;有的则需要做手术后,再用三棱镜矫正。但是,用光学眼镜、隐形眼镜矫正弱视眼难度较大。弱视眼分为两种:一是先天性弱视眼,自幼视力不良,虽说没有任何恶化症候,及长至学龄期则渐感视力降低,患者常合并为高度远视、近视或散光。这种情况,尚能用光学眼镜矫正。二是后天性弱视,也叫废用性弱视。其主要因素为两眼视力有差异,或者眼球原有病变引起视力和对光、色的感觉显著减弱。从实际病例看,单眼性弱视,多数可以矫正,视力得到改善。如:有的儿童 Myopia, farsightedness, astigmatism can wear glasses to correct, it is well known. In fact, strabismus, amblyopia and other eye diseases, wearing glasses can also play a role in correction. Cai Tei-yuan, director of the Beijing Factory 608, commented that children with strabismus can wear reading glasses of about 300 degrees at four to five years of age, while others need orthodontics after surgery. However, with optical glasses, contact lenses to amblyopia difficult to correct. Amblyopia is divided into two types: First, congenital amblyopia, his childhood poor eyesight, although there is no deterioration of symptoms, and as long as the school-age are gradually decreased visual acuity, patients often merged into a high degree of myopia, myopia or astigmatism. This situation can still be corrected with optical glasses. Second, acquired amblyopia, also known as disuse amblyopia. The main factor is the difference between the two eyesight, or the original eye disease caused by visual acuity and light, the feeling of color significantly weakened. From the actual case, unilateral amblyopia, most can be corrected, visual acuity improved. Such as: some children
