What are the three transparent structures that compose the ocular media?

The correct answer identifies the three transparent structures that comprise the ocular media: the cornea, lens, and vitreous body.

The cornea is the clear, dome-shaped surface that covers the front of the eye. It plays a crucial role in focusing light as it enters the eye. The lens is another transparent structure that further adjusts the focus of light onto the retina; it changes shape to help in viewing objects at different distances. The vitreous body is the gel-like substance filling the space between the lens and the retina, providing support and maintaining the shape of the eyeball while also being clear to allow light to pass through unhindered.

Together, these three structures are vital in facilitating vision by allowing light to enter the eye and be properly focused onto the retina, where it can be converted into neural signals for the brain to interpret. In contrast, the other options include either structures that are not transparent (such as the sclera and retina) or do not comprise the complete set of ocular media, which can lead to confusion regarding their roles in vision.
