a Schematic of corneal reflex examination (left), and the process of corneal reflex (right). b Schematic of corneal reflex evoked by mechanical stimuli. c Configuration of artificial corneal reflex arc responding to mechanical stimuli. d Schematic of the structure of the electrochromic device. e, f Digital images (e) and optical transmittance spectra (f) of the electrochromic device under different stimulation voltages. g Refractive index and extinction coefficient of the electrochromic device under different stimulation time. h Schematic illustration of the Li+ ions and charge transportation through the electrochromic device. i Digital images of electrochromic actuators under bilateral reflex (I), without reflex (II), ipsilateral reflex (III), and contralateral reflex (IV).
