Question

The retina of the eye acts as a
A) Lens in camera
B) Shutter in camera
C) Film on camera
D) None of these

Answer 1

The human eye produces real images. The light ray focused hits the retina at the back of the eye and forms a real image. The pupil adjusts according to the light similar to that of the camera.

Complete answer: The tissue layer (cornea) is the clear, semi-circular front layer of the attention. The pupil, behind the tissue layer, could be a hole within the colored membrane known as the iris. Small muscles within the iris modify the dimensions of the pupil – just like the aperture of a camera – to regulate the quantity of sunshine entering into the attention.
-There's a little, powerful lens behind the pupil that changes form to support the pull of muscles within the eye. Sort of a lens, the lens within the eye focuses incoming pictures from the skin world (incidentally, cataract surgery removes this lens and replaces it with a transparent artificial one).
-The membrane could be a skinny membrane that covers the back of the attention. Like film in a very camera, the membrane is that the photosensitive surface wherever pictures from the skin world return to attention. The membrane receives those pictures with scores of microscopic photoreceptor cells called rods and cones. Rods square measure sensitive to lightweight and dark, shapes, and movement. Cones square measure sensitive to fine detail and to paint.
-The tissue layer includes two areas known as the macula and therefore the fovea centralis. The macula is the name for a small oval close to the middle of the tissue layer, wherever cones square measure in high concentration and seeing is most acute. The macula is chargeable for receiving the sharp, straight-ahead pictures that square measure employed in reading, driving, biometric authentication, and so on. It’s 100 times a lot more sensitive to detail than the remainder of the tissue layer.
-The fovea centralis is known to be the center of the macula. It is sort of a pit and has the very best concentration of cones anyplace on the tissue layer. Under the neural tissue, the layer is the retinal pigment animal tissue (RPE), that provides nutrients to the photoreceptor cells – the rods and cones. -Behind these layers of the tissue, the layer is that of the choroid; this can be animal tissue and has blood vessels known as capillaries. Behind the tissue, the layer is that the albuginea – the structure of the attention.
Hence option C is correct

Note: The membrane (including the macula and fovea) sends pictures collected by the rods and cones as electrical impulses up the nervus opticus that is a cable designed of thousands of nerve fibers. It sends these impulses to the processing center of the brain, wherever they're taken as sight.
