Which structures does light pass through to reach the retina? Select all that apply.

To determine the structures that light passes through to reach the retina, it's essential to understand the pathway light takes as it enters the eye.

When light first enters the eye, it encounters the cornea, which is the transparent front layer that helps to focus light. Following the cornea, the light travels through the aqueous humor, a clear fluid that fills the space between the cornea and the lens, providing nutrients and maintaining intraocular pressure. The light then passes through the lens, which further focuses the light onto the retina at the back of the eye.

The structures of the sclera, while important for eye shape and protection, do not play a direct role in the passage of light to the retina, as they are opaque and do not allow light to pass through.

Thus, the correct structures that light passes through to reach the retina include the cornea, aqueous humor, and lens, emphasizing their crucial roles in the visual pathway.
