Globally, 1.1 billion people live with vision loss.
Almost everyone will need access to eyecare services during their lifetime
Distance vision
Almost 600 million people can’t see well in the distance
- 43 million people are blind
- 295 million people experience moderate to severe vision impairment
- 258 million people experience mild vision impairment.
Near vision
510 million people can’t see well at near

90 million children and adolescents live with vision loss
Of these:
- 2 million are blind
- 30 million experience moderate to severe vision impairment
- 58 million experience mild vision impairment
Projections
1.1 billion to 1.7 billion people by 2050
All categories of vision loss are set to grow:
