Vision impairments refer to a range of conditions that affect a person's ability to see clearly. These can include partial sight, where individuals may have some vision but not enough to perform everyday tasks, and total blindness, where there is no usable vision. Common causes of vision impairments include cataracts, glaucoma, and age-related macular degeneration. People with vision impairments may use various tools and techniques to assist them in daily life. These can include braille for reading, screen readers for computer use, and white canes for navigation. Early detection and intervention can help manage these conditions and improve quality of life.
