Scopes have different focal points designed for each type of rifle they are supposed to be mounted on. Scopes for .22 rim fire rifles do require you to put your eye right up near the eye piece to focus right, because those gun have no recoil. Those scope can be cheaper, even having similar power to hi-powered rifle scopes, but they carry warnings not to use them on anything but .22s. High-powered rifle scopes focus at a point that should keep your eye safely away from the eyepiece, even considering the expected recoil. On those scopes you can only see an image if your eye is several inches from the eyepiece.
