"Permanent Crescent Vision: The Aftermath of Staring at an Eclipse"

A woman who stared at the 2017 total solar eclipse without eye protection permanently damaged her eyesight, resulting in a crescent-shaped scar on her retina. The scar, resembling the phase when the Moon is about to block the Sun, is irreversible and serves as a cautionary tale for safe eclipse viewing. Experts advise using specialized glasses or indirect methods for observing solar eclipses, and warn against using regular sunglasses, binoculars, or cameras without proper solar filters.
