As mentioned previously, we should correct all optical errors of the eyes (glasses); eliminate eye muscle problems; and create smooth accurate eye movements. In addition, we should make sure that we properly interpret what we see and use it appropriately. These are known collectively as perceptual skills and include form perception, size and shape recognition, visual memory, and visual motor integration (hand-eye coordination.)
Ummm...Why are you wearing those?

What’s up with people wearing those big sunglasses after cataract surgery?
The main reason is for protection - physical protection to assure nothing hits the eye immediately after surgery, and protection from sunlight and other bright lights.
