passes the pupil it enters the lens‚ which can properly focus on the rear of the eye. Adaption allows the lens to change the thickness by flattening objects at a distance‚ or becoming rounded for closer objects. The eye’s retina then sends the image to the brain. The retina has a thin layer of nerves in the back of the eyeball. They consist of two light sensitive cells known as the rods and cones. Rods are cylinder shaped cells that are highly sensitive to light. Cones are well cone shaped and

important for things like depth perception‚ but occasionally it leads us astray. The cues make us think we see something that isn’t true‚ or isn’t even there. Light waves enter your eye and then enter photoreceptive cells on your retina. The image that forms on your retina is flat‚ but you see a world of shape‚ color‚ depth‚ and motion. Retinal images are flat representations on a curved surface. Most of the time‚ we perceive an accurate world of depth‚ surfaces and objects. Retinal images

Picking up a box from the floor and placing it on a shelf Light entering the eye forms an upside-down image on the retina. The retina transforms the light into nerve signals for the brain. The brain then turns the image right-side up and tells us what we are seeing. Our brain then computes to pick up the box. When a message comes into the brain from anywhere in the body‚ the brain tells the body how to react. the brain as a central computer that controls all bodily functions‚ then the nervous
