Q. When we see an object, the image formed on the retina is__:
Answer: Real and inverted
Notes: The retina is the thin light-sensitive membrane lining the inner eyeball-towards the back of the eye. As our eye lens are convex in nature, they form mostly real, diminished i. e. reduced size and inverted images on the retina. When the images formed are real and inverted, the message sent by the optic nerve are chemical impulses which turn them into erect images that we see.
