Vision loss refers to a decrease in the ability to see, which can range from minor difficulties to complete blindness. It can occur due to various factors, including age-related conditions like cataracts and macular degeneration, eye injuries, or diseases such as diabetes and glaucoma. People experiencing vision loss may struggle with daily activities, such as reading, driving, or recognizing faces. Early detection and treatment are crucial, as some conditions can be managed or improved with medical intervention, while others may require adaptive strategies or assistive devices to enhance quality of life.
