Glaucoma is one of the leading causes of irreversible blindness in the United States, and its prevalence is greater than previously believed. While there is no cure, early detection and treatment can slow progression and preserve vision. Medications, surgery, and lifestyle changes are all part of a comprehensive approach. One often-overlooked factor is diet. A growing body of research suggests that specific food choices can support eye health, potentially lowering intraocular pressure (IOP) and providing the nutrients needed to protect the optic nerve.
