Look what happens when you use a magnifying glass to start a fire. That's what can happen in your eyes

Now realize that after 3 minutes of totality, basically twilight, your eyes open up..so when the sun peeks out again you get those rays at max power

Note, you CAN look at the total eclipse but not when any sun is visible -- nm - zeitgeist Apr 8, 10:46 5
- No totality here and I have a meeting at in 13 minutes anyway :) -- nm - ty97 Apr 8, 10:47 4
  - who sets a meeting during an eclipse? -- nm - Pippy: Apr 8, 11:18 1
    - Clients on the other side of the world -- nm - zeitgeist Apr 8, 11:23
  - Look at the shadows of trees, the shape of it is projected hundreds of times ,quite cool really -- nm - zeitgeist Apr 8, 10:49 1
    - Yeah, for a partial eclipse, filtering the light through a collander or salad or pasta strainer is way more interesting -- nm - Beryllium Apr 8, 10:51
So is that to say it is okay to look as the eclipse is progressing, but not at totality? -- nm - ty97 Apr 8, 10:45 10
- other way around. -- nm - tRuMaN Apr 8, 10:48 1
  - Well, not exactly. It's just that people forget during the eclipse & instinct tells them it is "safe". And then their eyes get damaged. - Beryllium Apr 8, 10:50
- It's never okay. -- nm - Beryllium Apr 8, 10:46 7
  - It's actually ok at 100%, but the problem is anticipating when that ends. -- nm - Reagen Apr 8, 11:04
  - (Now, maybe there's something with eye dilation making it "safer" normally, that could be fair) -- nm - Beryllium Apr 8, 10:47
  - Got it, so it's not anything unique about an eclipse. It's a "don't stare directly at the sun ever" thing -- nm - ty97 Apr 8, 10:46 4
    - So why isn't the Donald blind. He looked at it twice for several seconds each time -- nm - zeitgeist Apr 8, 10:51 2
      - It's not instant, and maybe not even noticeable at first. The damage accrues over time. -- nm - Beryllium Apr 8, 10:52 1
        
        another zionist hoax -- nm - MAGA mud Apr 8, 11:01
    - That has been my take. -- nm - Beryllium Apr 8, 10:47
