Question

What happens to the image distance in the eye when we increase the distance of an object from the eye?

Answer 1

Hint:
Human eye has a convex/converging lens.
Human eye can change Focal length of its lens.
The image formed on the retina is an inverted image.

Complete step by step answer:
When we increase the distance of an object from the human eye, the image in the human eye remains the same because Human eye can change its focal length, therefore when the object distance is far or near it changes its focal length which does not disturb the distance of the object.
The image formed in our retina is an inverted image, but our brain depicts it as an erect one.
The image distance remains the same, because the human eye changes its focal length to balance with the image distance.

Additional Information:
Convex lens is a type of lens that is thicker at the middle and thin at its sides, it produces a real and inverted image.
Human eye produces 576 megapixels images, which is the highest by far.
Megapixel is one million pixels, it refers to the resolution of a digital image device, in our case we are considering Human eye.
Focal length is the distance between the middle bulged portion of a lens and its focus, that’s why it’s called focal length.
Aperture can be defined as the opening in a lens through which light passes to enter the camera, in our case human eye.

Note:
Human eye is the inspiration for the advancement of cameras.
Focal length of the eye can change.
When we are in a moving car and we see a car standing nearby the distance of the car standing is not felt until our eyes become incapable of increasing its focal length anymore.
Distance of the object remains the same.
