What is inverted image with the eye?

What is the lens present in your eyes that invert the image?

How can the orientation of an image of you eye changes as the concave mirror gets closer to your eyes?
As the concave mirror gets closer to your eye, the orientation of the image will change from upright to inverted. This is due to the changing focal length of the mirror, causing the light rays to converge differently. The closer the mirror gets, the more divergent the light rays will be, leading to an inverted image.
For instance when someone looks in the mirror do they look the same as they do to others or is their image flipped or naturally altered by the eyes?
When someone looks in the mirror, their image is flipped horizontally, so what they see is reversed compared to how others see them. This is because mirrors reflect an image that is laterally inverted.
