Which is the colored part of the eye?
The iris is the colored part of the eye that regulates the amount of light entering the eye. Lens: The lens is a clear part of the eye behind the iris that helps to focus light, or an image, on the retina. Macula: The macula is the small, sensitive area of the retina that gives central vision. It is located in the center of the retina. Optic nerve:
Where does the blood supply from the eye come from?
Our two eyes working together give us stereoscopic vision, and depth perception. The main blood supply of the eye arises from the ophthalmic artery, which gives off orbital and optical group branches. Innervation of the eyeball and surrounding structures is provided by the optic, oculomotor, trochlear, abducens and trigeminal cranial nerves.
How is the structure of the eye classified?
It is classified based on two aspects, namely external and internal components. External components include structures which can be seen on the exterior of the eye, and internal components include structures present within. External components include: Sclera. Conjunctiva.

What makes up the back of the eyeball?
The retina converts light into electrical impulses that are sent to the brain through the optic nerve. Vitreous gel: The vitreous gel is a transparent, colorless mass that fills the rear two-thirds of the eyeball, between the lens and the retina.
Which is part of the eye regulates light entering the eye?
The iris is the colored part of the eye that regulates the amount of light entering the eye.
Which is the opening at the center of the eye?
The pupil is the opening at the center of the iris. The iris adjusts the size of the pupil and controls the amount of light that can enter the eye. Retina: The retina is the light-sensitive tissue at the back of the eye. The retina converts light into electrical impulses that are sent to the brain through the optic nerve. Vitreous gel:
