Approximately 6 million Americans have vision loss and 1 million have blindness. More than 1.6 million Americans who are living with vision loss or blindness are younger than age 40. Over 350,000 people with vision loss or blindness are living in group quarters, such as nursing homes or prisons.
Prevalence. Globally, at least 2.2 billion people have a near or distance vision impairment. In at least 1 billion – or almost half – of these cases, vision impairment could have been prevented or has yet to be addressed.
Vision Atlas. Magnitude and Projections. Global Estimates of Vision Loss. More in this section. Globally, 1.1 billion people were living with vision loss in 2020. - 43 million people are blind (crude prevalence 0.5%) - 295 million people have moderate to severe visual impairment (crude prevalence 3.7%)
By 2050, we expect the number of people with visual impairment or blindness to double. Our infographics help illustrate trends in eye disease prevalence and steps people can take to prevent eye conditions and diseases.
In 2011, 2.71 million people in the United States had POAG, with the highest estimated number among populations aged 70 to 79 years (31%), women (53%), and non-Hispanic whites (44%). The largest demographic group is non-Hispanic white women.
We fitted hierarchical models to estimate prevalence (with 95% uncertainty intervals [UIs]) of moderate and severe vision impairment (MSVI; presenting visual acuity from <6/18 to 3/60) and blindness (<3/60 or less than 10° visual field around central fixation) by cause, age, region, and year.
We provide global estimates of the prevalence of corneal blindness and vision impairment in adults 40 years of age and older and examine the burden by age, sex, and geographic region from 1984 through 2020.
