This quote from "Seth Speaks" seems relevant to the OP question.
Seth says that you have visual images when you are born, internal visual images, symbols that are activated the moment you open your eyes for the first time. These serve you as learning mechanisms. You keep trying to utilize your eyes properly until exterior images conform with the inner patterns.
The eye-opening activates the inner mechanism. If there is something wrong physically with the eyes, if they are blind for example, then that particular mechanism is not activated at that time. The personality may have chosen to be born blind for his own reasons. If those reasons change, or if inner psychic developments occur, then the physical eyes will be healed and the inner mechanism activated.
