The eye's genuine potential is based on its ability to receive and process energy from light in the environment, generate activity possibilities in specific nerve cells, and transmit those possibilities to the mind via the optic nerve. The cornea, iris, ciliary body, and focal point all play a role in directing and focusing light onto the visible portion of the eye. The choroid, fluid, and vitreous humour, as well as the lacrimal framework, are important for physiological balance, correct pressing factor maintenance, and the survival of visual tissues. The physiology of the tears, cornea, focal point, glassy, and retina is studied in ocular physiology. Because the structure-work interaction is inseparable, understanding the physiology of the eye is a prerequisite for considering its design.
