Blindness is a lack of vision. It may also refer to a loss of vision that cannot be corrected with glasses or contact lenses. Partial blindness means you have very limited vision. Complete blindness means you cannot see anything and do not see light.
The leading causes of blindness and low vision in the United States are primarily age-related eye diseases such as age-related macular degeneration, cataract, diabetic retinopathy, and glaucoma. Other common eye disorders include amblyopia and strabismus.Vision loss can affect your physical health by increasing your risk of falls and your quality of life, and it can also have a big impact on your mental health. Loss of vision has been linked to loneliness, social isolation, and feelings of worry, anxiety, and fear. Depression is common in people with vision loss.
