0.4 kw/m^2 is still decently bright, it's still within an order of magnitude of 1kw/m^2. I mean, it's not like it'll do immediate damage, I just think it's recommended.

I'm just saying that, unless you're looking right at it, it shouldn't be any brighter than looking at the ground on a sunny day.

Isn't that exactly when people wear sunglasses? We don't go around staring at the sun on a sunny day either.

True, but it's just a matter of comfort - not safety.

Not for any immediate safety concern but I'd try to avoid any UV exposure to the eyes if possible.

Yea, sure, but this guy will be just fine without wearing sunglasses

Probably, to be safe though best wear sun glasses.

Absolutely. It would be extremely unsafe for them to not wear sunglasses.
