Vision consists of the photons that travel to your eye, your retina that detects them and encodes that for transport via the optic nerve to the visual cortex of your brain, where the perception or sense of vision actually happens. Even the tear film on the surface of the eye and the fluids inside the eye (aqueous humor and vitreous) have some degree of refractive ability. Its intensity is controlled by the adjustable diaphragm, the iris.
