Saving Eyesight worldwide

Our Work

Vision loss is linked to socioeconomic disadvantage. Poor vision contributes to inequalities for marginalised and socially disadvantaged populations. 90% of people affected of eye diseases live in low- and middle- income countries. Sub-Saharan Africa is one of the worst-affected regions.

2.2 billion people globally have a vision impairment
1.1 billion people are blind
90% of people with vision loss and blindness can be helped

Common causes of vision impairment and eye diseases

Cataract
As the world’s most common cause of blindness, cataract has taken sight from more than 20 million people. Age, injury or genetics can cause the typical cloudy lens. Cataracts can be corrected with a simple 15-minute operation.

Glaucoma
Glaucoma is another leading cause of blindness. Treatments include medication and operations. It is not possible to restore lost sight, but remaining sight can be preserved. Early detection is key!

Trachoma
Trachoma is the most common infectious cause of blindness worldwide. Repeated infections cause the inside of the eyelid to scar, making the eyelashes turn inward. These, in turn, scratch the cornea, leading to irreversible blindness. In the early stages, the disease is curable with antibiotics and preventable through improved hygiene. In the final stage, only eyelid surgery can prevent loss of sight.

Uncorrected Refractive Errors
153 million people live with a visual impairment, many due to uncorrected refractive errors. In most cases, a pair of glasses will allow them to see clearly again.

Child Blindness
About 2 million children worldwide are blind and 12 million are visually impaired due to uncorrected visual impairment, vitamin A deficiency, cataracts, untreated infections or injuries.

Our commitment for people with visual impairments

A eye health worker is holding up a vision screen test with letters. A girl student wearing glasses and the school uniform is a couple of meters in front of her leaning slightly to the right side with her head, trying to read the letters. Her school peers are behind her watching.

Vision screening can be future-changing. School screenings are conducted regularly in African regions.

A eye health worker is putting a pair of glasses on a man. He is looking at the mirror smiling. Next to the mirror there are a bunch of different types of glasses on display.

In Uganda, people get glasses that are customized for them.

In the early stages of the infectious disease trachoma, the infection can be treated with antibiotics.

Access to clean water, toilets and good hygiene practices prevents the spread of trachoma.
