How are images formed in the retina?
The retina is the thin light-sensitive membrane lining the inner eyeball- towards the back of the eye. When light goes into your eye it must pass through the lens (a biconvex lens) which inverts the image you are seeing- Basically- when you look at an image, let's say an apple, light bounces off the apple into your eye- as it enters your eye and passes through the lens the image gets inverted- reversed and flipped the other way- so that the image on your retina looks like an upside down apple going from right to left instead of left to right. Once this image is set on the retina, cone cells distinguish the color and detail while rod cells distinguish movement and shades of grey. The retina is connected to a nerve called the optic nerve- the image gets sent from the optic nerve to the occipital lobe in the brain where the image gets flipped and inverted once again to the proper image of the apple you first saw- and is finally interpreted.

it pasess up your behind then up your mouth into your eyes

Optic disc (blind spot)
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 interpr…ets 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.
if there is an object before a lens at a distance more than its focal length and is surrounded by a rarer medium it always forms the image on the other side of lens and is in…verted w.r.t object. our eye lens will simply act like a biconvex lens whose focal length is around 2.5cm . there fore images formed on the retina will be inverted and they are made upright by the brain system..
the image will be produced upside down because the focus point ins farther into the vitreous humor, but your brain will interpret th eimage right side up.
Light is focused by a lens to form an image in the retina.
The lens, which flattens or squishes up based upon the ciliary body's contraction or relaxation.
It can't. Lololololz.
The image is sent up with an electrical signal up threw the optic nerve and yh i think thats it
our eye has convex lens which has got the power of converging image . so when the light fall on the convex lens the sensory nerve of our eye immediately send electrical impuls…e to the mind then the mind make the clear and virtual image . or say when convex lens converge the falling light , the convex lens have a focus point which is retina at where all the light rays focused and images is formed .
The blind spot or optic disc
\n. Each light-sensitive receptor cell generates a signal in its attached optic nerve fibre, for transmission to the brain where the combined signals are processed to build u…p the image itself in our minds.
