Visual impairment, also known as vision impairment, is a condition that affects the ability to see. It can range from mild to severe, and can be caused by a variety of factors, including genetics, disease, and injury. People with visual impairments may have difficulty seeing objects clearly, distinguishing colors, or navigating their surroundings.
