Millions of people across the country turned their eyes to the sky to view the solar eclipse on Monday, Aug. 21st.
Also, the moon's covering makes it less painful to look at the sun longer, OH optometrist Michael Schecter told USA Today, which he noted was part of the problem.
Even pets are vulnerable to eye damage from looking at an eclipse, though they don't tend to look directly at the sun.
Those symptoms-blurred vision, yellow or dark spots, loss of vision in the center of the eye-would appear about 12 hours after exposure, likely when you wake up the following morning.
If someone did watch the eclipse without the glasses, there could be significant and lifelong eye damage.
"Patients that have symptoms just in one eye won't notice it because their other eye vision is normal and with both eyes open that better eye is compensating for the weaker eye", Weed said.
More than likely those symptoms would pop up nearly right away. Without proper eye protection, Dr. Weed said they would have the same symptoms as adults.
So how do you know if your child has damage? "It is a multitude of seconds, the prolonged exposure that you should be most anxious about".
Luckily, BuzzFeed reports a headache post-eclipse is probably not a sign of retinal damage.
"What it does is actually damages the cells in your retina, those are the cells in the back of your eye that provide fine vision and it can do permanent damage to those cells if you stare at the sun for long periods of time", said Williams.
"Solar retinopathy is not very common", said Dr. Jaime Membreno, an ophthalmologist at Retina Macula Specialists in Winter Park, Fla., in an email.
"There's no treatment, so getting in early versus late isn't gonna do anything", Price said. "So, get yourself checked out if there's any changes in vision". "My eyes felt kind of different, but no headache or anything like that".
Regardless of how many times people were warned not to look directly at the eclipse while it was happening, or to use a phone camera, DIY viewer or storebought glasses, some folks did, in fact, take it upon themselves to look directly at the solar eclipse.
