AP 105 Vision Flashcards
True or False: The retina is the innermost layer of tissue of the eye
True
True or False: The rods and cones are light sensitive cells distributed over the retina
True
Characteristics of the rod cells
-Most dense at the periphery of the retina
-Allow you to see gray tones under conditions of dim light
-Provide for peripheral vision
-More sensitive to light
Characteristics of the cone cells
-Require high light levels to function
-Densest in the center of the retina
-Allow you to see detail under bright light conditions
What is the primary function of focal vision?
Recognize and identify objects
What is the primary function of the peripheral vision?
To orient oneself relative to the environment
True or False: An object requires less motion to be seen in a clear blue sky than an object in a partly cloudy sky
False
In mid-air collisions, the primary peripheral visual cue of _____ is not available. Therefore, you must acquire the target aircraft with your ____ vision, using the scanning technique
Motion: Central
True or False: Perception/reaction time is affected by physiological and perceptual limitations
True
True or False: Maximum scanning effectiveness is achieved by a series of short (long enough for the eye to focus), regularly spaced eye fixations
True
What is the acronym used for reporting laser exposures?
LASER
