What if since human brains are likely different from the Steves, they don't see optical illusions like we do?

Now hear me out, this could be hilarious.

So imagine at some point during the series, for example just before the Curse arc, Sabre is on some kind of mission or something with Light and the Guards because he wanted to help out and they have to go through this old temple thing. However, just as any old temple it has its traps, and they all get caught in one. Nothing dangerous, don't worry.

So Sabre and Light are on one side of a wall, and the Guards are on the other side so it's like this teamwork puzzle thing in order to get out. Everything's fine for a bit until they get to one part where there's one of those optical illusions where it makes it so you can't see a thing, and Sabre is just extremely confused while Light is like "WHAT DO YOU MEAN YOU CAN'T SEE IT, IT'S RIGHT THERE!" And the Guard are all just absolutely cackling at this situation.

Or somehow they get to one that makes it hard to see it it's like on the walls or something and Sabre's just: *internal confused screaming*

Hehehehe
