Many were left in awe after the total solar eclipse carved its path across mainland USA on August 21. The symptoms may not show up for hours.
Searches for "My eyes hurt", "I can't see", 'Am I blind?' and 'What happens if you stare at the sun?' all spiked immediately after the eclipse passed over the United States on Monday. Or did you look directly into the sun like a dumb-dumb?
Exposure to the sun's light without the proper eye protection can destroy cells in the retina and cause "eclipse blindness".
"It is very possible it would be permanent damage", Post said. Symptoms begin occurring 12 hours after viewing the eclipse, when people wake up in the morning and notice their vision has been altered, TIME previously reported.

The grandmother of missing British boy Julian Cadman says she is "worried sick" as she waits for news about the seven-year-old. It is understood two men from Victoria were hit by the auto and injured, and both have since been discharged from hospital.
"At the New York Eye and Ear Infirmary emergency facility, we have already seen dozens of patients with concerns ranging from headaches to subjective blurry vision", said Dr. Avnish Deobhakta, an ophthalmologist with the New York Eye and Ear Infirmary of Mount Sinai Hospital. Because we don't have pain receptors in our eyes, pain won't be a factor in deciding if you've hurt your eyes, but there are other ways to tell if you accidentally damaged your peepers during the eclipse.
But in case that advice was forgotten, here's how to spot if you or a loved one got an unhealthy eyeful of the sun's rays.
Dr. Andrea Knouff says eye damage from the eclipse is no laughing matter. All of whom had indicated that they looked at the eclipse for 18 seconds or more. You can burn your retina, reports Time. "So, any sudden change of vision that stays and is permanent, come and get looked at".
Visit a local eye care professional for a comprehensive exam if you or a family member experience discomfort or vision problems following the eclipse. After the eclipse, many Americans who watched the celestial event unprotected complained about vision issues. But hopefully you had the right glasses to do it. If you looked at the sun during the eclipse with your naked eye, you might suffer from some of these conditions.
But if you did steal unprotected glances skyward, and especially if your eyes felt amusing or hurt a little afterward, you might be wondering how you'll know if you've done any long-term damage.
