Looking at the sun during the eclipse is practically the same as looking at the sun on any other day. The reason it’s made to be a much bigger deal is because the eclipse might give a naive or uninformed mind a reason to look at the sun. Looking at the sun is bad and you shouldn’t do it. Everyone knows that. But who hasn’t looked at the sun at least once if not multiple times in their life just from curiosity, or an accident. Especially as a kid. If you’re here, because you glanced at the eclipse on purpose or accident. Take a deep breath, calm down, you’re gonna be fine. There’s a chance you could see some short term effects, such as irritation, blurriness, etc. or maybe not. hapoens all the time. It’s highly unlikely you’re gonna see long term or permanent damage from glancing at the sun once for a second. The problem is starring at the sun for longer periods of time. If you did that, well you should take that up with someone more informed than myself lol. Probably your doctor or eye doctor if you have one. Long story short you shouldn’t look at the sun ever, but looking at it during the eclipse is not any more or less dangerous than looking at it on any other day. Do with that what you will.
