Acquired brain injury: damage to the brain acquired after birth that can affect
cognitive, physical, emotional, social or independent functioning
Amblyopia (lazy eye): involves lowered acuity (visual clarity) and/or poor eye muscle control in one eye; often results is a loss of depth perception
Convergence insufficiency: a common eye teaming/binocular vision disorder where the eye don't work easily together for near-distance activities, such as reading or computer viewing; a person can have 20/20 vision and still have convergence insufficiency
Eye Alignment: ability of both eyes to gaze in the same direction; a deviation in alignment typicall results in strabismus, or a crossed/turned eye
Eye Teaming: ability of both eyes to "point" at the same object at the same time Eye Tracking: ability of both eeys to smoothly and simultaneously follow words on a page or moving objects
Depth perception: the ability to see in 3-D; involves the eyes and brain working together to perceive spatial relationships, such as distances between objects
Developmental (behavioral) optometry or functional vision care: the branch of optometry focusing on the practice of vision threapy; involves the evaluation of vision skills and visual perceptual performance, as well as how the environment, nutrition and behavioral factors affect visual performance
Double vision (diplopia): a medical condition of vision where a person focuses on a single object but it appears double
Dyslexia: difficulty reading by persons with "normal" vision and intelligence/processing abilities; there are three types of dyslexia (PDF)
Focusing: ability of the eyes to maintain clear vision while look quickly from near to distance or distance to near
Primitive reflexes: reflexes necessary for infants to have during birth and for the first few weeks after that have not yet develop into more complicated reflexes
Sports vision (Definition by the American Optometric Association at www.aoa.org)
Strabismus (crossed eye): an eye that turns up, down, left or right
Syntonics (light therapy or phototherapy) (Definition by the College of Syntonic Optometry at www.syntonicphototherapy.com)
Visual acuity: the ability to see clearly at a given distance
Visual closure: the ability to recognize familiar figures that have been partially obscured, distorted or deleted from sight
Visual discrimination: the ability to see the similarities and differences in forms, shapes, objects, letters, words, etc.
Visual memory: the ability to remember what has been seen, without relying on subvocalization, tactile, or auditory feedback; the act of forming a mental visual image of something seen before or previously visualized
Visual motor integration: the ability to match visual and motor skills in the brain, such as copying a series of pictures or forms
Visual processing: ability of the brain to make sense of information taken in through the eyes
Vision skills: the combination of "good" eye teaming, tracking and focusing and visual perception
Visual space orientation: the eyes and brain working together to perceive relative positions of objects in their visual field
Vision therapist: a specially trained profession who implements vision therapy procedures
Vision therapy: an individualized program of visual procedures used to retrain the brain and eyes to work efficiently together |
