Physical exercise is well-known for its systemic health benefits, particularly in cardiovascular and metabolic health. However, its role in ocular health is an emerging area of interest. This review explores the current evidence on how regular physical activity can prevent and manage various eye diseases, including glaucoma, diabetic retinopathy, age-related macular degeneration (AMD), and cataracts. The underlying mechanisms, such as improved ocular blood flow, reduced intraocular pressure (IOP), and enhanced metabolic control, are discussed to provide a comprehensive understanding of how exercise contributes to maintaining eye health.
