Red Eye Spot: Commonly Harmless but Sometimes a Warning
A sudden red spot on the eye, known as subconjunctival hemorrhage, is usually harmless and resolves on its own, but recurrent cases or those in older adults may indicate underlying health issues like high blood pressure or systemic vascular problems. It often results from minor trauma, eye rubbing, or increased venous pressure from activities like coughing or straining, and requires medical attention only if persistent or accompanied by other symptoms.
