If the eye lens is a converging lens, why do we see an upright image?


Converging lens, also known as Convex lens is the type of lens that is thicker in the middle but thinner at the edges. It is found in cameras, microscopes, telescopes, eyeglasses, and even in the human eye.

As our eyes are a converging lens, when the light rays enter, it converges at a point on the retina and forms a real and inverted image of the object. Now, this real and inverted image formed on the retina is conveyed to the brain through the optic nerve and gives rise to the sensation of vision, where our mind interprets the image as that of an erect or upright object. Also, depending upon the position of the object, both diminished and magnified images can be produced.
