Abilities Sight & Visual Impairment
A visual impairment means that vision or sight is limited to some extent. This varies from reduced vision in one or both eyes (low vision) to substantial irreversible loss of vision in both eyes (blindness). Some people have limited or no sensitivity to (certain) colours (colour blindness), or an increased sensitivity to bright colours.
There are many choices for accessing information with a visual impairment. Traditionally formats like braille, large print and audio are still very popular, however, nowadays digital devices including braille displays and magnification to screen reader are increasingly used. Formats like HTML, EPUB and Accessible PDF are important digital standards for accessible information.
UKAAF was originally founded to support visual impairment and this continues to be an important area of research and standards. For further information on braille, large print, audio, HTML, EPUB, Accessible PDF and Accessible images for sight and visual impairments please follow the links.
