It’s funny you say that. I have astigmatism, but I learned to see these on demand before I got glasses to correct it. The tricks all involve getting your eyes to focus farther away than the actual image surface. I could easily see the butterfly while wearing my glasses. Then I read your comment and tried again without my glasses and I could still see something but it was no longer a cute butterfly. Without my glasses, it was an abyssal horror with wings unfolding from other wings in a vaguely butterfly configuration.
Do you need both eyes for this? One of my eyes is almost useless and also lazy, the other one has… Something, I don’t recall what, but it’s all blurry from up close and hard to focus. Guessing astigmatism. I don’t wear glasses.
Yes, it’s entirely dependent of tricking your eyes into changing their angle as if they are looking at something farther away than the image actually is.

Two eyes are how humans have depth perception, yes.
