Visual impairment is defined by the Worls Health Organisation (WHO) as a decreased ability to see to a degree that causes issues that are not fixable by usual aids like glasses or similar, while the term blindness is used for people with complete or nearly complete vision loss.

STATISTICS

CAUSES

Globally, the leading causes of vision impairment are:

• uncorrected refractive errors like near-sightedness, far-sightedness, presbyopia, and astigmatism.
• cataract (major cause for blindness)
• age-related macular degeneration
• glaucoma
• diabetic retinopathy
• corneal opacity
• infections
• childhood blindness
• Visual impairment can also be caused by problems in the brain due to stroke, premature birth, or trauma, among others.

Vision impairment severely impacts quality of life among adults without an adaptive training and equipment. Adults with a vision impairment often have more difficulties finding a job, or they may deal with psychological disorders. Moreover, this impairment can be a cause of social isolation, difficulty with walking and carrying out other daily activities.

Because of the hardships they face, the web used to be inaccessible for people with visual impairments until support systems were implemented.
