|
|
Term
|
Definition
| When the cornea is misshaped, ligh waves become distorted and cause impaired vision |

|
Definition
| Innermost layer of the eye that contains the photoreceptor cells |
|
|
Term
| Photoreceptor Cells (Rods and Cones) |
|
Definition
Rods - Help us see in dim light and dark conditions
Cones - Help us in visual acuity, seeing in lighted conditions and seeing color |

Definition
| Where light is reflected directly onto our optic nerve |
|
|
Term
|
Definition
| Kinesthhetic cues for depth derived from sensations of muscular contractions of the extraocular muscles and of the lens. |
|
|
Term
|
Definition
| Cues for depth that are purely visual in nature |
|
|
Term
| Two Types of Oculomotor Cues |
|
Definition
Accommodation - When the lens of the eyes adjust their thickness in order to focus on an object.
Vergence - When the eyes move in opposite directions either inward (convergence) or outward (divergence) |
|
|
Term
| Binocular and Monocular Cues |
|
Definition
Binocular - Presence of both eyes
Monocular - Presence of one eye |
|
|
Term
|
Definition
| The difference in lateral separation between two or more objects in our visual fields that communicates to us how far various objects are from us. |
|
|
Term
| Static and Nonstatic Cues |
|
Definition
Static - Stationary
Nonstatic - In Motion |
|
|
Term
|
Definition
| Objects closer will appear to move faster through the visual field than those farther away. |
|
|
Term
|
Definition
| When one object partially obscures the presence of another |
|
|
Term
|
Definition
| Larger objects are generally closer |
|
|
Term
| Linear and Texture Perspective |
|
Definition
Linear - When things become closer together the farther you look
Texture - When things become less textured the farther you look |

Definition
| Extends outward from the head and trieds to capture as many sound waves as possible and direct them to the ear drum |
|
|
Term
|
Definition
| Thin membrane that vibrates in response to sound waves and relays the waves further through the middle ear and through the inner ear |
|
|
Term
|
Definition
| Contains the ear drum and three small bones (hammer, anvil, and stirrup) and functions to amplify sound waves |
|
|
Term
|
Definition
| Part of the inner ear that vibrates in response to the stirrup of the middle ear and transmits the vibrations to the cochlea. Also helps to balance the pressure in the inner ear. |
