PARTS OF THE EYE AND THEIR FUNCTIONS I Eye Models and Their Explanations
ANATOMY OF THE EYE The eye itself is divided into three, namely the front, middle and back. Here are the parts of the eye that you need to understand:
1. Front
Cornea
The cornea is the part of the eye that is at the front and has a clear or clear color. This part functions to focus and transmit light to the eye. This part also functions as an eyeball protector.
Iris
The iris is the colored part of the eye that helps regulate the amount of light entering the eye. When there is bright light, the iris closes the pupil so that only a little light enters the eye. Meanwhile, when the light is dim, the iris opens the pupil to let in more light.
