What about astigmatism? Second class eye issue? The balls would look like eggs. Source: all circles I see look like eggs.
Yeah, that’s about right. When I look at the moon, there’s a second slightly dimmer moon above it that overlaps by about a third. Lights at night are a cluster fuck; I can’t tell a low bed trailer from a standard box trailer. The doubling of the tail lights on a low bed look like the second set of upper lights on a box trailer. I have a hard time focusing in low light. Also, my brain can’t render 3D without my glasses.
My glasses are really thick to make up for my astigmatism, and it makes the world look a bit convex. Eventually, my brain got used to that, but when I switch to contacts I have a good day or two where everything looks concave (first time I thought my phone screen had finally been sat on one too many times) until my brain reverts back. IDK if i’ve ever noticed circles looking like eggs, but then again I rarely am looking at circles with my naked eyes and maybe my brain is fixing it for me anyway?
