From more complex eyes, retinal photosensitive ganglion cells send signals along the retinohypothalamic tract to the suprachiasmatic nuclei to effect circadian adjustment and to the pretectal area to control the pupillary light reflex. Ready to be used in web design, mobile apps and presentations. hide column This column uses an eye icon to indicate whether the layer is visible. Image-resolving eyes are present in molluscs, chordates and arthropods.The simplest "eyes", such as those in microorganisms, do nothing but detect whether the surroundings are light or dark, which is sufficient for the entrainment of circadian rhythms. Eyes with resolving power have come in ten fundamentally different forms, and 96% of animal species possess a complex optical system. In higher organisms, the eye is a complex optical system which collects light from the surrounding environment, regulates its intensity through a diaphragm, focuses it through an adjustable assembly of lenses to form an image, converts this image into a set of electrical signals, and transmits these signals to the brain through complex neural pathways that connect the eye via the optic nerve to the visual cortex and other areas of the brain.
Eyes detect light and convert it into electro-chemical impulses in neurons. They provide animals with vision, the ability to receive and process visual detail, as well as enabling several photo response functions that are independent of vision.
