Question

Quizplus · Accepted Answer

Macular degeneration is a disease that causes a loss of central vision, making it difficult to see fine details, such as objects in close proximity. It is often associated with aging and is more common in those with a history of smoking. Glaucoma, cataracts, and retinal hardening do not typically cause a loss of central vision.
