What are you talking about, i never said that people look at sun and say they are ok.
Most eye damage occurs because of UV light not general brightness, aka wavelengths out of the visible spectrum.
And it is also time based, that's why a brief glance towards the sun doesn't damage eyes (so the important part to your comment is what does look 'mean'.
Your logic may seem sound to you on wider pupil but it isn't.
For example when folks look at bright lights the pupil will contract and you can still get damage from prolonged looing at sun via narrow pupil.
Bottom line unless you can start showing studies about damage from 10k nits of visible light spectrum you are just opining.
As the dude says "it's just like your opinion, man".
As is my reply is mine, the difference, I at least attempted to find studies to support your position - there are zero.
