Answer 1

it will be real inverted

Answer 2

First a clarification; light passing through the lens of your eye is focused on the retina which detects the light and electrically signals the brain. The brain then interprets the signals and provides you with an “image". Using a lens to focus light is a thoroughly investigated process that adheres to scientific principles and our understanding of light. How the brain processes signals from the retina to create an “image" is the subject of ongoing research.
