Some serious eye problems include macular degeneration, cataracts and diabetic retinopathy, according to the Centers for Disease Control and Prevention. These primarily age-related conditions are the leading causes of blindness and poor vision in the United States.
Macular degeneration is a condition that affects the macula, the central part of the eye's retina, which is responsible for central vision and seeing fine details, the Centers for Disease Control and Prevention explains. The macula becomes damaged, making tasks such as driving and reading difficult.
A cataract is a clouding of the eye's lens and is the leading cause of vision loss in the United States, the Centers for Disease Control and Prevention states. It is estimated that 20.5 million Americans over age 40 have a cataract in at least one eye, which is more than 17 percent of the population. Cataract treatment is widely available in the United States, but some patients lack the insurance coverage or money to receive it.
Diabetic retinopathy is a complication from diabetes that is the leading cause of blindness in Americans between 20 and 74 years old, the Centers for Disease Control and Prevention reports. It is caused by deteriorating blood vessels in the retina. It can be often be treated if diagnosed early enough.
