Question

In human eye lens is convex which forms inverted image but we see the object erect.Why?

Answer 1

As you can see , the light makes the man look inverted inside our eye . but before entering optic nerve , it again gets reflected from the eye wall and becomes erect .

Answer 2

let's say you're looking at an arrow that is pointing up.from the physics point of view,light rays from the upper extremity (the top) of the arrow reach a point on your retina that is lower than the light rays coming from the bottom extremity (the base) of the arrow. which means that the formed image of the arrow on the retina is upside down (pointing down).however, your conscious visual perception of the arrow is still pointing up,because the brain interprets this inverted image on the retina.
