FAQ: How can you go blind from looking at a solar eclipse?

How long can you look at a solar eclipse before going blind?

Why does a solar eclipse cause blindness?

Research confirms that staring at the sun — even one that is completely blocked by the moon — can cause eclipse blindness. The American Optometric Association defines eclipse blindness as “a serious injury in which the eye’s retina is damaged by solar radiation within seconds of staring at the sun.”

Is it OK to watch solar eclipse with naked eyes?

A solar eclipse can be viewed safely with the naked eye only during the few brief seconds or minutes of a total solar eclipse, when the Sun itself is completely obscured by the Moon. Failure to use appropriate filtration may result in permanent eye damage or blindness.

Can eclipse blindness be cured?

Why can’t we look 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.
