Human eyeballs vs fish eyes

Hoi hoi

Ive heard you cant trust space or balloon photos because of fish eye lense effect.
How can you say theres a curve when theres obvious fake lense curve.

So RE and FE smart guys.
Our eyes our round balls.
There is a fish eye lense effect in what we see.
Its just always there so we dont notice.
How can you be sure your FE level water is actually level?
How can you be sure the horizon isnt curved but flattened out due to the fish eye?
How can you be sure your RE curved earth isnt actually flat?

We have two eyes.
Both fished.

People tend to use fish eye lens incorrectly. Wide angle lenses will have some distortion. it can be predicted and accounted for.
Our eyes are not fisheye lenses.

It’s not the shape of the camera-housing or the eyeball that counts, it’s the lense’s focal point that matters.
