If you stared straight at the eclipse without any kind of special eye protection and you're experiencing blurry or impaired vision, you should probably go see an eye doctor.
It usually takes 24 hours before you start noticing symptoms, and there's no pain because there aren't any pain receptors in the retina.
Nurse Practitioner Trish Patterson at Prestige Urgent Care in Redding told KRCR News that she heard some people put sunscreen on their eyeballs to watch the eclipse:
"One of my colleagues at moonlight here stated yesterday that they had patients presenting at their clinic that put sunscreen on their eyeball, and presented that they were having pain and they were referred to an ophthalmologist."
Why does this even need to be said to people? Don't look at the sun, and don't put sunscreen on your eyeballs!!
