In the order light passes through the eye, which structure comes last before reaching the retina?

• A. Vitreous humor
• B. Cornea
• C. Pupil
• D. Lens

Answer: (A)

Light travels through the eye in a specific sequence: it enters through the cornea, moves through the aqueous humor in the front chamber, passes through the pupil, goes through the lens, and then travels through the vitreous humor before finally reaching the retina. The last structure it passes through before hitting the retina is the vitreous humor. This is because the vitreous fills the large space behind the lens, forming the final transparent medium that leads light to the retina. The lens sits in front of it, and the pupil is just an opening, so neither of those is last.
