Sight is not just having a visual image of your environment and reality, but being aware of all the connections and using them to have the broadest and most open perception . In his essay, Sacks suggests that sighted individuals are blind to reality because they tend to ignore internal connections, relying heavily on others. By ignoring these connections, a limited perception develops, an interpreted reality that does not use all the senses available. With blindness, Sacks describes how these individuals have a more open and enriched reality and environment because they use all of their senses. In doing so, "Dennis... had increased his sensitivity to other people's moods and to the finer nuances in their speech and self-expressions... He felt that he had become much more sensitive to the emotional states of others others since he lost his sight." , because he was no longer fooled by visual appearances, which most people learn to disguise” (8).

Not using all connections creates an inaccurate reality, an environment that is not truly seen and is generated by self-deception. Not seeing reality, or having perception, means not seeing the world and the environment at all. Yet it is still possible to share perceptions with someone else and be perceptually enriched by those of another person
