Which structure of the eye refracts, or changes, the direction of light rays after they enter the eye?
A. Pupil
B. Sclera

The cornea is the main structure in the eye responsible for refracting light, accounting for approximately 70-75% of the eye's refractive power. After light passes through the cornea, it continues through the pupil and is further focused by the lens onto the retina. The correct answer to the question is option C: Cornea.

The cornea is the primary structure that refracts light in the eye, accounting for most of the eye's total refractive power. It works in conjunction with the lens to focus light onto the retina. The pupil's role is to regulate light entry, while the sclera provides protection and structure. ;
