The video tutorial explores how cameras and human eyes function similarly in capturing images. It explains the components of a camera, such as the aperture, lens, and sensor, and compares them to the eye's pupil, lens, and retina. The tutorial also covers how eye doctors use optics to correct vision issues, employing tools like glasses, contacts, or laser surgery.
