why the image reaches inverted to brain/eye?

Answer 1

The reason for this is simple if one understands optics. The rays of light as they enter the eye have to pass through the lens. Each eye of ours has a convex lens. i could have drawn a simple diagram but I don't know how it can be drawn here. Anyway, the property of a convex lens is that the image gets inverted and is real for an object that sends parallel rays into the eye of the object is beyond the principal focus of the lens.

Answer 2

The image is not inverted in the brain but it is inverted when the light rays passes through our lens it becomes inverted. It is because our lens is a concave lens which is a converging lens. All the light rays are converged at focal point which is in the eye, at this point the rays make an inverted image which is read by the brain and an erect image is obtained.

Answer 3

Because our lenses are convex lenses, thus images reach our retina inverted. Our nerves in the retina translate the images 'reinvertedly' and transmit the signals to our brain, so our brains receive the correct image.

Answer 4

The crystalline convex lens of each eye projects an inverted image on the retina. Optic nerve fibers from each eye crisscross at optic chiasma the junction of two optic nerves and these fibers reach optical cortex of both sides for giving three dimensional erect and singular interpretation of images from both eyes by brain

Answer 5

Image gets inverted in lens of the eye itself nerve fibres in lower part of retina get upper part of image & vise versa. so the imgae get trnasmitted to vision part of cortex in inverted direction

Answer 6

uh? i learnt somewher but i forgot now
