In the path light takes through the eye, which structure comes second?

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

Answer: (B)

Light entering the eye follows a specific path. It first hits the cornea, which does most of the bending of light. After the cornea, light passes through the pupil—the opening in the iris that regulates how much light enters. This makes the pupil the second structure light encounters. Behind the pupil, the lens further refines focus, and the vitreous humor fills the space to support the eye as the image is formed on the retina. So, the second structure is the pupil.
