The opening through which light enters the eye.

Explanation:
Light enters the eye through the pupil, the opening formed by the iris. The iris can widen or constrict the pupil to regulate how much light reaches the lens and ultimately the retina. Light first passes through the cornea, then the lens focuses it onto the retina where photoreceptors detect it. The sclera is the white outer coating, not involved in light entry, and the retina is the light-detecting layer at the back. So the opening through which light enters is the pupil.
