The eye membrane is composed of several parts, including the IRIS (4 letters), RETINA (6 letters), sclera (6 letters), uvea (4 letters), and cornea (6 letters). The IRIS is the colored part of the eye that controls the amount of light entering the eye. The RETINA is a thin layer of tissue at the back of the eye that contains light-sensitive cells and helps to form images. The sclera is the white outer layer of the eye that protects the inner structures. The uvea is the middle layer of the eye that contains blood vessels and helps to regulate the pressure inside the eye. Finally, the cornea is the transparent front layer of the eye that helps to focus light onto the RETINA. Together, these components make up the eye membrane and are essential for vision.
