VISUAL SKILLS Flashcards
conscious ability to move both eyes in a certain direction
Eye movement controls
both eyes able to focus, simultaneously, on an object/area in the distance
Simultaneous focus at distance
both eye maintaning the focus of an object/area in the distance
Sustaining focus at distance
both eyes being able to focus at the same time at an object/area at near
Simultaneous focus at near
both eye maintaining the focus of an object/area at near
Sustaining focus at near
both eyes simultaneously directed at an object in the distance
Simultaneous eye alignment at distance
the ability to keep both eyes looking at the same object in the distance
Sustaining eye alignment at distance
both eyes looking at the same object at near
Simultaneous eye alignment at near
ability to keep both eyes looking at the same object at near
Sustaining eye alignment at near
measure of how small of an object a person can see at a given distance
Central visual acuity
area visible to the eyes outside of central vsision
Peripheral vision
ability to judge distances or depth, ability to perceive distances between objects in three dimensions
Depth awareness
ability to perceive and distinguish different colors, most notably red, green yellow, blue
Color perception
one’s ablity to control large muscles of the body for activitees such as pointing at an object, catching or throwing a ball, stepping over an obstacle etc.
Gross visual-motor skills (eye/hand coordination)
one’s ability to control small muscles of the body such as hands and fingers while writing or drawing etc.
Fine visual-motor skills
ability to interpret information derived from the eyes relative to a person’s surroundings
Visual perception
ability to integrate information from the eyes with the other senses, also the tying together of multiple visual skills
Visual integration
awareness and attention to objects
Fixation
to know the distance where the object is recognized
Fixation
to know if the patient uses his sense of sight or using other senses
Fixation
following objects with the eye or head
Tracking
to know if the patient can follow objects at different position of gaze
Tracking
to know if the patient can follow the moving objects without losing
Tracking

Scanning
to know if the patient has difficulty from changing fixation from 1 point to another
Scanning
