Lmfao no, I don't actually believe that. I wrote an incredibly stupid/sarcastic comment on purpose of some tinfoil hat shit you could possibly see over there. People kinda got that at first I believe then that whole comment section kinda got in some stupid argument so people took it seriously. If you understood my kind of humor in real life you would get it but obviously you don't.
He has a point though, so did julian assange a while back. Looking at the sun is bad, yes. But is looking at partially blocked sun during an eclipse worse? "But muh pupil dilation" doesn't work since a part of the sun is blocked and only that part of the em radiation would reach our eyes, so our pupil would adjust to that amount of light (including UV) accordingly. I've heard arguments that the retina would be damaged by the UV from the corona, but 99% of the sun's corona is blocked by the moon because sun is a sphere. The only argument that makes sense is that they think we're all retards and have publicized this "threat" so retards don't blind themselves watching the whole eclipse progression bare eyed.
"But muh pupil dilation" doesn't work since a part of the sun is blocked and only that part of the em radiation would reach our eyes, so our pupil would adjust to that amount of light (including UV) accordingly.
As far as I understand it, the point is that the damage is done depending on the intensity (power per area), while pupils dilate or contract based only on total power. So during an eclipse it's easy to expose small parts of retina to like 20x more intense light (due to the pupil being dilated) without feeling much discomfort. Which should be more than enough to burn out the pieces of your retina that sunlight actually fell on, even if the total amount of sunlight was 100x smaller than usual.
Also, your eyes don't adjust to UV because you can't see it.

You don't know what a corona is. It's that shit that looks like sun rays or something and extends to half or full extra sun radius outside. Except if you think a little, there's no unrelated dust for sun rays to reflect from, and that's actually super-hot (100,000K vs 5700K of the Sun surface) plasma being bright all on its own. Idk if it can hurt you though, most of the UV is blocked by the atmosphere anyways.
How is total power reaching a square centimetre of retinal tissue different from power per area? If the sun is blocked 50%, total power received is 50%. What are you even trying to say?
Are you saying that the eye focusses on the center of the eclipsing disc while the sneaky sun pushes some UV rays to the outer retinal cells? Then why do people who claim to be blinded by eclipses (very very few btw) claim that they have a blind spot at the center of their vision?
You don't know what a corona is blah blah, I'm smarter than you blah blah..
Yeah, if you had used your PhD trained brain to try to understand what I said you would have realized that I was actually referring to claims I came across.

Imagine a lens the size of a distended pupil. Like, a water drop. That water drop can focus sunlight to ignite paper.
Like, your problem is that you don't think about the lens in our eyes that focuses light on the retina, and think about the light that goes through the pupil. It's not just "light that comes through the pupil", it's where that light goes.
If sun is 99% blocked then your pupil will be distended as if it were nighttime, I couldn't find hard numbers but it looks like it would have a 20 times larger area than the pupil you look at the sun with normally. So 20 times more sunlight focused on a crescent-shaped area on your retina, per area. That's going to boil that area.
Yes, on average, it's 1% of the normal sunlight. But due to the pupil being distended, that's 20 times more sunlight hitting some particular place. If you somehow managed to look at the sun with a fully distended pupil during the day, and keep looking, you'd have a sun-shaped burn on your retina. During the eclipse you can get a thin crescent-shaped burn easy as fuck.

Or maybe I'm the fucking retard and my satire detector is broken. It's hard to tell.

No, I'm fairly certain at least 60% believe that rainbows are a gay conspiracy/recruitment tool.

/u/The_Warhawk77 your glasses post was sarcasm right? I honestly can't tell anymore

Lmfao do you honestly believe that. If yes, please get your handlers to take you to the vet to get neutered

I like how both of you are arguing the merits of looking directly at the sun.
Sun = bad for eyes
No look right at sun without eye protection. Sun like fire but burn eyes instead of cook food. Sun give big owie if looked directly at.

Fuck off, NASA shill. Sun > makes carrots grow > improves eyesight.

Which is still more than the eye can take in without damage.
1 flipkt 2017-08-22
Correct. My point is in support of some of the points made by the OP in the_donald thread
1 0xnull 2017-08-22
The sun doesn't get more dangerous, but the way people act during an eclipse does. That's why we need the warnings and glasses.
1 flipkt 2017-08-22
Thanks for paraphrasing the last part of my original comment, I guess.

I wasn't really sure what comments from t_d you were referencing, but ya, pretty much the same as yours.
