Vision Vocabulary

3. processing: the brains natural mode of information processing from many functions including vision.
7. theory- the theory that the retina contains three different types of color receptor: red, blue, and green.
11. inability to recognize familiar faces
14. Cells: neurons in the retina that transmit signals to the brain via the optic nerve, receive input from bipolar cells.
16. sidedness: Light from distant objects is rejected by the cornea. The image focuses Infront of the retina instead of on the retina making distant objects blurry.
18. Vision Deficiency: caused by damage or irregularities in cones and ganglion cells.
20. caused by damage to the primary visual cortex.
21. of the eye: Enters though the cornea then to the pupil surrounded by the iris, then hits the transparent lens and then it is focused to an image on your retina.
22. where cones are found, center point of the retina.
23. the transparent structure behind the pupil that changes shape to help focus images on the retina, inverts the image so it’s projected into the back of the eye upside down, center of retina
24. The adjustable opening in the center of the eye where the light enters.

1. one cone is missing, perceives only two-color channels.
2. the process by which the eye’s lens changes shape to focus near or far objects on the retina.
4. visual illusions that persist after the removal of the visual stimulus
5. thin, photosensitive layer of tissue located at the back of the eye.
6. sidedness: Light from nearby objects is refracted by the cornea and lens. Nearby objects are blurry while distant objects are clear.
8. detect color and detail, needed in daytime vision.
9. no functions cones, vision is only black, white, and gray
10. spot: the area where the optic nerve enters the eye.
12. theory- The theory that opposing retinal processes enable color vision.
13. sensory system: the complex biological system responsible for detecting and processing light to enable vision, allowing us to perceive color, light levels, contrast, and motion.
15. occur when retinal ganglion cells are overstimulated and then rebound with the opposite color
17. Compensation: “fills in” the missing information from the blind spot using cues from surrounding visual data and the other eye.
19. detect shape and movement, needed for nighttime vision.
