During Friday's In Depth segement, we were joined by Dr. Priti Panchal, an optometeric physician from the Eye Institute of West Florida.
Viewing an eclipse without proper eye protection can damage the retina, which is the delicate, light-sensing tissue that is responsible for your ability to read and recognize faces.
"If you are out on a sunny day, and you look up at the sun, you look away right away," Panchal said. That's because your pupils have adjusted to the daytime conditions.
"Whenever the solar eclipse happens, things are going to be more dim, so the pupils are going to be a little more dilated and not as constricted," she said. "So when people are looking at the sun, it's actually allowing more sun to come in."
Some locations Monday are in the "route of totality" as it relates to the eclipse, but Panchal said proper glasses should be worn no matter where you watch the eclipse.
Panchal also dispelled some myths about what to wear -- and what not to do.
Two pairs of sunglasses? No.
Pinhole in a box? That's fine.
Holding up your hands to shield the sun? Definitely no.
Panchal explained the difference between looking at the sun during the day versus sundown at the beach.
"Your pupils are a little more constricted, still allowing protection for the eyes," she said. "It's a little more dusk, (the sun) is not as strong."
Depending on the extent of the injury, people can suffer temporary vision loss, residual blurring and/or distortion or permanent vision loss.
