Blindness, also known as vision impairment or sight loss, refers to a lack of visual perception. It can range from partial sight loss to complete blindness, where an individual cannot perceive any light. The causes of blindness are varied and can include genetic conditions, age-related diseases like macular degeneration and cataracts, infections, injuries, and chronic illnesses such as diabetes.

The impact of blindness extends beyond the visual sense, affecting an individual's independence, mobility, and ability to perform daily tasks. However, many people with blindness lead fulfilling lives by utilizing assistive technologies, such as screen readers and braille, and by developing other senses to compensate for the loss of sight. Rehabilitation programs and support services play a crucial role in helping individuals adapt to blindness and maximize their potential.

Globally, millions of people experience vision loss, with a significant portion of these cases being preventable or treatable. Efforts to combat blindness focus on early detection, access to quality eye care, and public health initiatives aimed at addressing the underlying causes of vision impairment. Research continues to explore new treatments and technologies to restore or improve vision.
