You could insert a second lens in the focal path, between the object and the first lens. The second lens can be designed (or moved) to focus the image on the screen.
This is the same function that eyeglasses do for people with poor vision. The second lens, the eyeglasses, are inserted between the viewed object and the lens of the eyes. The second lens is designed to correct the distortion of the eye lens, thus creating an in-focus object on the "screens" of the eyes.

What is the change in an objects position over time without a direction?
Speed --- actually, if your question is 'position' over time, there is no answer since position is a vector quantity. And position divided by time will still yield a vector quantity-- velocity. If the question asks for change in distance over time, then the answer is speed. --gh ---

What it the distance an object travels in a certain period of time without regard to direction?
The distance an object travels in a certain period of time without regard to direction is known as the object's displacement. Displacement is a vector quantity, meaning it has both magnitude (length) and direction. It is calculated by subtracting the initial position of the object from its final position. For example, if an object starts at position (2, 4) and ends at position (6, 8), the displacement would be (4, 4). Displacement is a vector quantity It has both magnitude (length) and direction It is calculated by subtracting the initial position of the object from its final positionTo put it simply, displacement is the distance an object travels in a certain period of time without regard to direction.
