Blindness

A condition characterised by the complete or near-complete absence of functional vision, ranging from no light perception to minimal light awareness that cannot be used for practical tasks. Blind individuals typically rely on non-visual senses and assistive technologies such as screen readers, braille displays, and audio descriptions to access information and navigate their environment. Blindness is one of the most widely considered conditions in digital accessibility, with standards like WCAG and technologies like ARIA designed to ensure that digital content is perceivable without sight.
