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.

If light enters your eye but does not properly form an image on your retina what would you expect to happen?
your brain would get a signal for a blurry image
the cornea, which is a clear outer covering, refracts light onto the 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 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.
They are real, however, everything your eyes take in is upside down. So the screen you're looking at now is actually upside down to your eyes. However, your brain, in it's spl…endor, flips the image the right way!
when an image goes through the eyes the image that forms in the retina is upside down and the brain has to flip it back the right way. And its a real image. Image formed … in simple words is real and inverted
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 horizo…ntal 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.
What is the nature of eye lens of human eye and that of the image formed at the retina of the eye by it?
the human eye lens is convex and the image formed at retina is real and inverted
The cornea and the crystalline lens. Approx. 2/3 of the focusing power comes from the cornea, and 1/3 from the crystalline lens. This structure can also change shape to allow …us to focus at different distances. The process of changing crystalline lens shape, and hence allowing us to focus, is called accommodation.
Smaller than the object viewed. Upright. Closer to the optical device than to the object. Real Image.
The image should form on the retina. More specifically in the fovea centralis of the macula of the retina.
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.
The thing that focuses the retina is the pupil. the light rays pass through the cornea into the pupil while passing through a cavity which contains a jelly-like liquid called …aqueous humor.then the rays pass through the pupil to the lens.the light rays are converged by the lens and the aqueous humor to an extent that it focuses the rays of light on the retina(yellow spot).
The image of an object formed on the retina of the human eye is called Image Formation. Image Formation is the natural processing of light through the eye.
The image may be "real" ... but the data that goes to your brain is NOT. You see only "fragments" of the image - edges, lines, contrasts, frequencies (NOT colors), … and it all gets "reintegrated" in your occipital lobe That is - your brain must build up a model from the data it gets - inverting it is a cinch.
