Vision is the dominant sense. 80% of what we are required to learn comes in by way of sensory input through the visual system.Vision is a complex combination of learned skills, including
- eye movement coordination (tracking)
- binocular fusion (eye teaming)
- accommodation (focus)
Eyesight is the ability to see clearly. A common misconception is that 20/20 eye sight means you have perfect vision. Seeing clearly is important, but far too much emphasis is often placed on it. You can have 20/20 eyesight and still have serious functional vision problems.
The level of development of a person’s visual skills determines how well they are able to acquire and process information through the eyes. If input is poor, output is poor. Often times when there are visual skills deficients, there are difficulties with visual form perception (recognizing the difference in shapes); figure-ground perception (ability to pick out information that matters from that which is irrelevant); directionality in space (ability to tell up from down and left from right as in the case of differentiating b,d,p,q and ‘was’ from ‘saw’); and visual-motor coordination (integrating vision and body in situations requiring eye hand skills such as writing or catching a ball)
Because vision is learned, it’s possible for visual development to take an inappropriate path leading to a number of visual deficits. This can cause difficulty in reading, writing and ultimately how we learn and processing information.
