Difference between vision and visual perception

There is a critical difference between problems in vision and visual perception. Problems with vision consist of problems with the physical components of the eye and function of the eye. Perception of vision is a function of the brain. Problems with perception of vision may occur in children with Autism. However, it is important to note that many children with Autism have excellent visual perception abilities. So, problems with visual perception need not be defined as co-morbidity, and can occur in a case-dependent manner.
