Recent data suggest that there are 37 million blind people and 124 million with low vision, excluding those with uncorrected refractive errors. The main causes of global blindness are cataract, glaucoma, corneal scarring (from a variety of causes), age-related macular degeneration, and diabetic retinopathy.
It would appear that the global Vision 2020 initiative is having an impact to reduce avoidable blindness particularly from ocular infections, but more needs to be done to address cataract, glaucoma, and diabetic retinopathy.
最新数据表明，不包括未矫正屈光不正者，全球有3700万盲人以及1.24亿视力低下者。全球失明的主要原因是白内障、青光眼、角膜瘢痕（由多种原因引起）、年龄相关性黄斑变性和糖尿病视网膜病变。
全球“视觉2020”倡议似乎正在产生影响，以减少尤其是由眼部感染导致的可避免失明，但在应对白内障、青光眼和糖尿病视网膜病变方面仍需做更多工作。
