How long do I have to stare at the sun to go blind?

Can you go blind by staring at the sun?

Beware … damage will occur! When you stare directly at the sun—or other types of bright light such as a welding torch—ultraviolet light floods your retina, literally burning the exposed tissue. It destroys the rods and cones of the retina and can create a small blind spot in the central vision, known as a scotoma.

Can your eyes heal from sun damage?

The eyes can heal after sun damage, but they may experience some vision changes. Many eye problems caused by sun damage are cumulative, meaning they result from repeated and consistent sun damage over many years. Cataracts, pterygium, and macular degeneration are treatable, but will not resolve on their own.
