Yep! Each eye has a tiny blind spot where the optic nerve leaves the retina. Your brain cleverly fills in the gap.
Your eyes constantly make tiny movements called saccades to take in different parts of a scene.
Optical illusions work because your brain interprets visual information, sometimes producing a perception that differs from reality. 🌀
Surprise, fear, excitement and other emotions can change pupil size, making your eyes react before you consciously notice.
