Final answer:
The globe of the eye refers to the entire eye structure and is better known as the eyeball. It encompasses various components essential for vision, including the lens, iris, cornea, and retina.
Step-by-step explanation:
The globe of the eye is most accurately referred to as the eyeball. It is not the lens, which focuses light onto the retina, nor the orbit, which is the bony socket that houses the eyeball. The retina is the light-sensitive tissue at the back of the eye. When discussing the globe of the eye, we are referring to the entire spherical structure that houses various components essential for vision, including the lens, iris, cornea, and the retina.
The cornea is the transparent protective layer on the front of the eye, and the iris is the colored part of the eye that regulates the amount of light entering the eye by adjusting the size of the pupil. The optic nerve is responsible for transmitting visual information from the retina to the brain.
