Visual impairment refers to a significant reduction in the ability to see, which cannot be fully corrected with glasses, contact lenses, or surgery. This condition can range from mild vision loss to complete blindness. People with visual impairments may have difficulty seeing objects clearly, distinguishing colors, or perceiving depth, which can affect their daily activities and independence. There are various causes of visual impairment, including cataracts, glaucoma, diabetic retinopathy, and age-related macular degeneration. These conditions can result from genetic factors, injuries, or diseases. Early detection and intervention are crucial for managing visual impairment and improving the quality of life for affected individuals.
