Question

BlackTom AI · Accepted Answer

The question asks for the name of the opening in the iris through which light enters the eye.
Option 1: 'pupil.' The pupil is precisely the opening in the iris that allows light to pass into the interior of the eye, where it reaches the lens and retina. This matches the definition asked for.
Option 2: 'lens.' The lens is a transparent, flexible structure that sits behind the iris and focuses light onto the retina; it is not an opening.
Option 3: 'cornea.' The cornea is the clear, dome-shaped surface at the front of the eye that helps to refract light, but it is a covering, not an opening, and does not form the entry hole itself.
Option 4: 'iris.' The iris is the colored part of the eye that surrounds the pupil and controls its size by contracting and dilating; it is not the opening, but rather the tissue around it.
In summary, among the options provided, the term that corresponds to the opening through which light enters the eye is the pupil.
