In many airplanes, there are legitimate restrictions on how tall you can be as a pilot -- there simply isn't enough room up there for taller pilots to fit.
As for eyesight, I'd imagine it's for the case when the pilot loses/breaks/forgets their glasses. You don't want a pilot who suddenly can't see in midair.
