Khurana categorizes the eyeball into three distinct layers or "coats": Outer Fibrous Coat: Includes the transparent (the watch-glass of the eye) and the white Middle Vascular Coat (Uvea): Comprised of the ciliary body , this layer is the eye's primary nutrient supplier. Inner Nervous Coat (Retina):
The first surface light encounters, providing a smooth optical interface.
A transparent, avascular structure that acts as the primary refractive element. It allows light to enter and bend (refract) it toward the lens. anatomy and physiology of eye ak khurana pdf
