# Blindness

Blindness describes severe, permanent loss of vision that significantly limits everyday activities, even with the best possible correction. Definitions vary between countries and organisations.

## Causes

Many eye and neurological conditions can lead to blindness.

- Globally common causes include cataract, glaucoma, age-related macular degeneration, and diabetic retinopathy
- Inherited retinal dystrophies, corneal opacity, and childhood conditions such as retinopathy of prematurity
- Trauma, infection, and stroke affecting visual pathways
- Socioeconomic factors influence access to prevention and treatment

## Support and adaptation

Rehabilitation helps people remain as independent as possible.

- Orientation and mobility training, including white-cane skills and guide dogs
- Assistive technology such as screen readers, braille displays, and audio books
- Psychological support and peer groups to address emotional impact
- Social and occupational services to support education and employment
