Did you look at the solar eclipse too long? Doctors explain signs of eye damage

Did you look up at the solar eclipse without your safety glasses? Looking at the sun — even when it's partially covered like during the eclipse on April 8 — can cause eye damage.

There is no safe dose of solar ultraviolet rays or infrared radiation, said Dr. Yehia Hashad, an ophthalmologist, retinal specialist and the chief medical officer at eye health company Bausch + Lomb.

"A very small dose could cause harm to some people," he said. "That's why we say the partial eclipse could also be damaging. And that's why we protect our eyes with the partial as well as with the full sun."
