A vision:

Eye is a ball shaped muscular organ in a little hollow area the eye socket in the skull in the front part is protected by the eyelid. The main function of the eyelid is to keep the eye clean and moist by opening and shutting several times a minute. The eyelid is muscle skin that protects the eye and it also has great reflexes, which are automatic body responses, which protect the eye. Eye is one of the most complicated organs to study because it has a lot of parts working together to give a complete vision like lens, cornea, retina, and other parts. Light first passes through a cornea, which refracts the light and then passes through a lens, which refracts the light further, so that it forms a focused image on the retina.

Parts of the eye:

Cornea is a part that is exposed to light and the surrounding and it is a clear white thing over the outside of the eye that helps the eye focus like a lens on a camera. Iris is that part of the eyes that has color and as it gets bigger and smaller to let in different amounts of light. Pupil is a Black opening in the middle of the eye and light comes through this opening. The aqueous humor is clear watery stuff that keeps the eye clean and it also provides nutrition to the eye. A lens is that organ that bends light and it also helps the eye see close up and far away things. The retina has nerve cells called rod cells and cone shaped cells those are at the back of your eye.

Chamber of the eyes:

Between the iris and cornea is the anterior chamber and this chamber is filled with a special transparent fluid that gives the eye oxygen, protein, and glucose which is a type of sugar in the body so that it is kept healthy. It is seen that the pupils will get smaller when the light shines near them and they'll open wider when the light is gone.

Green eyes:
