In a short essay (100–150 words), describe three ways in which the structure of the lens of the human eye is well adapted to its function in vision.
Include a 5-10 sentence explanation of how the sheep’s eye senses light and relays that data to the brain to interpret visual information. Some pieces to consider:
What path does the light travel?
What structures and pigments does it interact with?
How does the signal travel to the brain?
Where in the brain is the data processed?
How is this different in the high light vs low light?
How might the sheep’s vision differ from our own?

- Watch this video (http://openstaxcollege.org/l/l_3-D1) to learn more about how the brain perceives 3-D motion. Similar to how retinal disparity offers 3-D moviegoers a way to extract 3-D information from the two-dimensional visual field projected onto the retina, the brain can extract information about movement in space by comparing what the two eyes see. If movement of a visual stimulus is leftward in one eye and rightward in the opposite eye, the brain interprets this as movement toward (or away) from the face along the midline. If both eyes see an object moving in the same direction, but at different rates, what would that mean for spatial movement?arrow_forwardWhy is it easier to see images at night using peripheral, rather than the central, vision? Cones are denser in the periphery of the retina Bipolar cells are denser in the periphery of the retina Rods are denser in the periphery of the retina The optic nerve exits at the periphery of the retina.arrow_forwardFigure 36.18 Which of the following statements about the human eye is false? Rods detect color, while cones detect only shades of gray. When light enters the retina, it passes the ganglion cells and bipolar cells before reaching photoreceptors at the rear of the eye. The iris adjusts the amount of light coming into the eye. The cornea is a protective layer on the front of the eye.arrow_forward
