Visual defects are common in deaf individuals. Refractive error and ocular motor abnormalities are frequently reported, with hyperopia, myopia, astigmatism and anomalies of binocular vision, all showing a greater prevalence in deaf individuals compared with the general population. Near visual function in deaf individuals has been relatively neglected in the literature to date. Comparisons between studies are problematic due to differences in methodology and population characteristics. Any untreated visual defect has the potential to impair the development of language, with consequences for education more generally, and there is a need to improve screening and treatments of deaf children.
视觉缺陷在聋人中很常见。屈光不正和眼球运动异常经常被报道，远视、近视、散光和双眼视觉异常的发生率均高于普通人群。迄今为止，聋人近视力功能在文献中相对被忽视。由于方法学和人群特征的差异，研究之间的比较存在问题。任何未经治疗的视觉缺陷都有可能损害语言的发展，对教育产生更广泛的影响，因此需要改善聋童的筛查和治疗。
