Translation for ppl that doesn't speak spanish: The eye is a visual organ that perceives light and converts it into electrochemical impulses that travel through neurons along the optic nerve. The simplest photoreceptor cell in conscious vision associates light with movement. In higher organisms, the eye is a complex optical system that captures light from the surroundings, regulates its intensity through a diaphragm (iris), focuses the objective thanks to an adjustable lens structure (crystalline) to form the image, which then converted into a set of electrical signals that reach the brain through complex neural pathways that connect, through the optic nerve, the eye to the visual cortex and other brain areas.123
