At times I will tell parents of children that I
have assessed that their child is not seeing
properly. The child all the while doesn't know
any different, thinking that seeing double
is normal or they have been labeled with
inattentiveness but are unaware that their
eyes aren't seeing properly. The parents
often will tell me that they have just seen an optometrist who said that their child has 20/20 vision, with good visual acuity. However seeing and vision are not the same. Vision deals with the part of sight that receives the image on the retina to be processed. Having 20/20 vision does not necessarily mean you have perfect vision. 20/20 vision only indicates the sharpness or clarity of vision at a distance. Seeing however is the physical process of sight, how well can we steer and control our eye muscles to see. It's made up of four elements: focus, teaming, fixation, and eye tracking. Together, this is what is called "eye fitness".
