Fact 1
In 2010, the number of people visually impaired was estimated to be 285 million, of whom 39 million were blind. This represents a reduction in the number of people previously estimated as being visually impaired in 2004.
Fact 2
An estimated 120 million are visually impaired because of uncorrected refractive errors (near-sightedness, far-sightedness or astigmatism). Almost all of them could
Fact 6
Age-related causes of visual impairment and blindness are increasing, as is blindness due to uncontrolled diabetes.
Fact 7
Globally, up to 80% of visual impairment and blindness in adults is preventable or treatable.
Fact 8
Infectious causes of blindness (onchocerciasis and blinding trachoma) are being progressively eliminated from the world with effective and innovative public-private partnerships
Fact 9
Around 1.4 million children are blind. The major causes of blindness in children include cataract, retinopathy of prematurity (ROP), and Vitamin A deficiency. Approximately half of all childhood blindness can be avoided or treated. A global programme in 30 countries, through a partnership between WHO and Lions Clubs International, is providing eye care services to children.

Fact 2
An estimated 120 million are visually impaired because of uncorrected refractive errors (near-sightedness, far-sightedness or astigmatism). Almost all of them could
have normal vision restored with eyeglasses, contact lenses or refractive surgery.
Fact 3
90% of visually impaired people live in low- and middle-income countries.
Fact 4
An estimated 51% of all blindness (19.7 million) is due to age-related cataract, the leading cause of blindness, while 43% of all visual impairment is due to uncorrected refractive errors.
Fact 5
Cataract surgery and correction of refractive errors are among the most cost-effective health interventions.

Fact 10
For decades, WHO has been working with its Member States and its international partners to eliminate the main causes of avoidable blindness, by providing technical assistance, monitoring and coordination.
