Question

How do the following process occur? When we see an object, a real inverted image is formed on the retina.

Answer 1

Because the eye lens is a convex lens and the object is well beyond he centre of curvature of the lens. We know that in case of a convex lens, real and inverted images are formed. Therefore When we see an object, real and inverted image is formed on the retina.

Answer 2

Answer:

• the retina is the light sensitive membrane lining the inner eyeball, towards the back of the eye.
• when light goes into your I it must pass through the lens (a biconvex lens) whitch inverts the image.
• basically, when you look at an object, light bounces off the object into your eye.as it enters your eye and passes through the lens the image gets inverted and reversed and flipped the other way.
• so that the image on your Tina looks like an upward down object going from right to left instead of left to right.
• once this image is set on the retina, cone cells distinguish the colour and details, while rod cells distinguish moment and shades of grey.
• the retina is connected to a nerve called the optic nerve.the image is sent from the optic nerve to the brain where the image gets flipped and inverted once again to the proper image of the object you first saw and is finally interpreted.
