The Great Solar Eclipse of 2017 has come and gone. Likely, you looked at the sun during it (you weren맥스카지노�t supposed to). Now, your head hurts (you맥스카지노�re not imagining it). You맥스카지노�re worried about eye damage (you맥스카지노�re probably fine). But here맥스카지노�s how to tell if you맥스카지노�re not.It takes about 12 hours to tell whether or not any permanent damage has occurred, professor emeritus of optometry and vision science at the University of Waterloo Ralph Chou told NPR. The kind of retinal damage caused by looking at this kind of eclipse isn맥스카지노�t painful, so you have to rely on other symptoms to know if damage was incurred: blurred vision, a spot (or multiple spots) at the center of your field of vision, or a clear spot.Again, the chances you맥스카지노�ve actually caused serious damage are minimal, chief of ophthalmology at Englewood Hospital Jacob Chung explains to USA Today. The sun isn맥스카지노�t any more damaging during an eclipse than it is on any non-historical-eclipse-filled day, but you맥스카지노�re more tempted to look at it, hence all the panic: "If you look at it for a second or two, nothing will happen. Five seconds, I'm not sure, but 10 seconds is probably too long, and 20 seconds is definitely too long.맥스카지노�Still, if you맥스카지노�re worried, you have reason to be:Any damage in this realm is likely irreversible, ophthalmologist Sweta Kavali said in a Saint Louis University video. If you are concerned, go see an optometrist or, ideally, an ophthalmologist.
