blindness

Blindness refers to the significant or total inability to see, which can result from damage to the eyes, optic nerves, or parts of the brain that process visual information. It may be present at birth or develop due to injury, disease, or aging. While some individuals are completely unable to perceive light, others may have some residual vision. Blindness affects daily functioning and often requires adaptive strategies and assistive devices. It is a diverse condition with varying causes and degrees of impairment, emphasizing the importance of personalized support and accessibility.
