All it took was 20 seconds.

Thats how long two Oregon men say they looked at a partial solar eclipse with their naked eyes 55 years ago before it burned their retinas, causing permanent blindness.

Nothing has changed, 70-year-old Lou Tomososki told NBCs Today show of the damage he sustained. It doesnt get any worse or better.

Tomososki said he was walking home from high school in Bend, Oregon, with his friend, Roger Duvall, in 1962 when they both looked up at the sun, each with one eye.

Both men are now warning people who plan to watch Mondays eclipse to make sure they do so with proper safety protections.
