Go back and think of the stupidest things you’ve ever done in your life, and then reassure yourself they’re not nearly as stupid as what a lot of people did during the solar eclipse. According to reports, people actually applied sunscreen to their eyeballs to protect them from the suns harmful rays while staring directly at the eclipse.

An article by WCMH Channel 4 in Ohio claims that patients have been treated at area hospitals for putting sunscreen on their eyes. It quoted a nurse practitioner who said that patients went to a local clinic complaining of pain after putting sunscreen directly on their eyeballs, and were then referred to an ophthalmologist.

It is not unusual to get sunscreen in your eyes, since it is often applied to the face area, and since sweat can cause it to drip in your eyes. So it’s possible not all cases were of people doing incredibly stupid things.

“It’s common sense not to stare directly at the Sun with your naked eyes or risk damaging your vision, and that advice holds true for a partially eclipsed Sun,” NASA says on its website on how to stay safe. “But, only with special-purpose solar filters, such as eclipse glasses or a handheld solar viewer, you can safely look directly at the Sun. NASA recommends that people who plan to view the eclipse should check the safety authenticity of viewing glasses to ensure they meet basic proper safety viewing standards.”
