Have you ever wonder what’s there in your eye that sees? Is it the eyeball or cornea? If not, then think about it. Knowing different parts of an eye with functions will be helpful to know more about the thing through which we see every color in our life. Also, our eyes are the most delicate part of our body. So let’s discuss what its parts and functions are.
Tear Layer
Tears are the most essential for our eyes and vision. Every time any particle enters our eyes, it washes that away. Also, it reduces the risk of eye infection and maintains the lubricant in our eyes. The fluid is essential for the overall functioning of the eye.
Cornea
The cornea is the front part of the eyes that holds eyeball in it. The main function of the cornea is to reflect or bend light rays. All the light that enters our eye is only through the cornea. It has five layers and composed of protein and cells. Also, there are no blood vessels. Thus tears and water fluids provide nutrients to it.
Anterior Chamber
It is the space behind the cornea and in front of the iris. The anterior chamber is filled with aqueous humor which supplies nutrients to the cornea. The main of this part is to remove waste particles and give shape to the eye
Iris
Iris is the thin part in our eye that gives color to the eye in optical terms. As it controls the diameter of the pupil thus controls the light entering the eye through the retina. Iris, in our eye, is strongly pigmented with the colors.
Lens
By changing its shape lens changes the focal distance of the eye. Its focus on the light rays that fall on the retina. The aim is to clear the image of the object that is placed at a distance. It is biconvex intraocular tissue, although its shape and size vary.
Vitreous Humour
It is located at the back of the eye and comprised around 80% of the chamber in an eye. Consist of 99% water, it is like a transparent fluid between lens and retina to balances the eye parts. The main aim is to protect the eye and helps in holding a spherical shape.
Retina
It is a thin layer of the tissue that is located near the optic nerve. The main aim is to receive light that is reflected by Iris and send it to the lens. Thus it converts the image to an electrical impulse for the brain to interpret
