20,476,040 people in America age 40 and older have cataracts

2,227,485 people in America age 40 and older have glaucoma
Glaucoma is a disease that causes a gradual degeneration of cells that make up the optic nerve. As nerve cells die, vision is slowly lost. Often, the loss of vision is unnoticeable until significant nerve damage has occurred.
Diabetic Retinopathy (PDF)
5,353,233 people in America age 18 and older have diabetic retinopathy
Diabetic retinopathy is a common complication of diabetes affecting the tiny blood vessels of the retina. These vessels can break down, leak, become blocked, or abnormal new blood vessels may grow on the surface of the retina -- impairing vision over time.
Age-Related Macular Degeneration (AMD) (PDF)
1,651,335 people in America age 50 and older have AMD
Age-related macular degeneration (AMD) primarily affects the part of the retina responsible for sharp central vision. Dry AMD (non-exudative) is the most common form of the disease. Wet AMD (exudative) is less common, but is more threatening to vision.
