Answer 1

If you take a penny and hold it one inch from your eye, you won’t be able to read the date on it, because human eye binocular vision isn’t really built to visualize something that close. And relatively speaking, a penny is huge.

An ant, and other tiny things, are more likely to have evolved to see things a millimeter in front of them, so yes, I’m guessing an insect would be able to see a crumb of a crumb of cake that a human wouldn’t.
