Optics - Do I live in a smaller world with glasses?
Gee, I never really thought about it.
The only way we can tell what the world looks like is through our senses.
We must accept what our senses tell us, since we have no other way to observe reality.
We can only tell if we are in a bigger or smaller world, if we can compare.
Just now you were able to compare.
However, I think it is the other way around.
Through your glasses you see the world as you'd see it if your eyes were "normal".
Without your glasses you are living in a bigger world (that is slightly out of focus).
