The image that falls on the retina is inverted. To better understand this, observe any image around you, better yet, look at your computer screen. Now imagine drawing a horizontal line across your computer screen. Every image above that horizontal line, is focused on the inferior portion of your retina. The same applies for all the images found below that horizontal line, those images are focused on the superior portion of your retina.
Inverted, just like the image on film through a lense on an old fashioned box camera. But...your brain accepts the info off the retina and through your optic nerve and interprets it as right side up.
I have READ (but do not know for a fact) that experiments have been made where special lenses are put in front of the eyes to reverse the image (so the image is actually right-side-up on the retina), and after about 3 days the brain will reprogram itself and interpret things correctly....and when this experiment is stopped, after about 3 more days the brain reprograms itself and again interprets things "normally." I cannot cite where I read this, and I don't even remember if the experiments were with humans or animals (probably monkeys)...but it stuck with me at the time.
The image is inverted
It is inverted.

Dictionary Definition:A layer at the back of the eyeball containing cells that are sensitive to light and that trigger nerve impulses that pass via the optic nerve to the brain, where a visual image is formed.Here is a diagram:http://www.topnews.in/healthcare/sites/default/files/retina.jpg
The eye. The retina coats the back - inside of the eyeball. It is where all the photosensitive cells reside. It is a flat black colourl
They die because when a sheep lies on its back it can't get back up again, but when it does lie on its back the skin on top of the sheep falls on to its lungs which stop it from breathing.
The tapetum helps them see at night. It is behind the retina. When light goes through the retina, it strikes the tapetum and passes back through the retina, illuminating the image on the retina a second time. This is why it looks like their eyes glow when light hits them at night. The light is escaping out through the pupil.
The retina is the only part of the cow's eye that has blood in it. The retina is the layer of tissue on the back portion of the eye.
A real and inverted image is formed on the retina.
Retina (layer of nerve tissue covering the back 2/3 of the eyeball).
Your Retina
the back portion of the eye
They don't intentionally lay on their backs but yes if they are large sheep, or have a large fleece or are weak and get cast on their side or back they will only be able to get upright if helped by the farmer.
An Immelman is performed by pulling the stick back and entering a vertical climb. Constant back pressure on the stick will place the aircraft inverted on a 180 degree heading from the original vector. The aircraft is then rolled upright, completing the Immelman.
Light rays reflect off the object and into the eye where they are refracted by the cornea and focussed by the lens on to the retina, the optic nerve then carries the messages to the brain and an image is formed. Answer: Images don't form in the eyes they form in the brain.The retina at the back of the eye receives light energy from the exterior environment. This is much like the reception of radio wavs by an antenna.The activated optic nerves transmit electical signals or messages to the brain which interprets the impulses into an image
The only light that travels through the body is the image seen by the retina at the back of the eyeball. It travels through the lens and is inverted. This is sent by the optical nerve to the brain where it is turned right side up again.
A retina is in the eye. At the back of the eye is the optic nerve. yes and in the front is the cornea Wrong,retina is in the back of the eye.(:
why does your retina pick up colour in thee back but not the outside?
