a Anatomy of human eye, mainly consisting of cornea, pupil, lens and vitreous body and retina. Cones and rods as photoreceptor cells in the retina are mainly responsible for perceiving the intensity of light, as well as the visual adaptation functions. Visual adaptation when exposed to b soft light and c bright light. Top: schematic diagram of how images of a lotus evolved through visual adaptation over time. Bottom: the mechanism of visual adaptation via dynamically switching between rod and cone cells
