Our brains can play tricks on us and cause us to perceive things inaccurately. We may think we see something clearly with our own eyes, but we can often miss details and changes right in front of us due to phenomena like change blindness and inattention blindness. While sensation provides raw data to our senses, perception is influenced by expectations, assumptions, and prior knowledge that can sometimes lead us astray.
