A free human eye diagram can be created using EdrawMax. The human eye is a sense organ that reacts to light and allows vision. Rod and cone cells in the retina are photoreceptor cells that are able to detect visible light and convey this information to the brain. The human eye’s non-image-forming photosensitive ganglion cells in the retina receive light signals, which affect the adjustment of the size of the pupil, regulation, and suppression of the hormone melatonin. Not many people know this, but the eye also receives oxygen through the aqueous. Its function is to nourish the cornea, iris, and lens by carrying nutrients, it also removes waste products excreted from the lens, and maintains intraocular pressure, and thus maintains the shape of the eye. This gives the eye its shape.
