How does sight takes place?

Answer 1

The individual components of the eye work in a manner similar to a camera. Each part plays a vital role in providing clear vision. So think of the eye as a camera with the cornea, behaving much like a lens cover. As the eye's main focusing element, the cornea takes widely diverging rays of light and bends them through the pupil, the dark, round opening in the center of the colored iris. The iris and pupil act like the aperture of a camera.

Next in line is the lens which acts like the lens in a camera, helping to focus light to the back of the eye. Note that the lens is the part which becomes cloudy and is removed during cataract surgery to be replaced by an artificial implant nowadays.

Answer 2

They have a lens that focuses an image onto the retina that has photoreceptive cells called cones and rods. They are stimulated by light and then send their information to the brain's occipital lobes that processes that information into an image. i think he's right, damnnn.

Answer 3

It is the ability that many organisms have evolved to interpret light signals so as to form an image of the organism's surroundings. The organ that can pick up the light signals is called an eye. Eyes of different organisms ranges from simply being able to detect where light is present or not to being able to see in detailed coloured images like our own. Organisms with sight have a clear advantage when hunting, evading or even just moving around.

Answer 4

Sight is light hitting your cornea and being absorbed into the brain. The brain then processes the colors and shapes and creates the image in milliseconds. The image is constantly updated and thus you see the moving images.

Answer 5

The light passes through the lens of the eye to the retina. The optic nerve then picks up the signal and transmits it to the proper area of the brain. The brain then interprets the information.

Answer 6

Sight occurs when light enters the eye through the cornea and is focused by the lens onto the retina at the back of the eye. The retina contains cells called photoreceptors (rods and cones) that convert the light into electrical signals. These signals are then transmitted to the brain via the optic nerve, where they are interpreted as visual information.

Answer 7

A sense of sight allows organisms to hunt and to avoid the danger of being hunted themselves.
