Verified step by step guidance

Identify the anatomical structure in question: The problem asks for a transparent extension of the sclera that lies in front of the pupil.

Understand the function and location of each option: The iris is a colored part of the eye that controls the size of the pupil, the retina is the light-sensitive layer at the back of the eye, the lens focuses light onto the retina, and the cornea is a transparent structure that covers the front of the eye.

Focus on the key characteristics: The structure must be transparent and an extension of the sclera, which is the white part of the eye.

Eliminate options that do not match the criteria: The iris, retina, and lens do not fit the description of being a transparent extension of the sclera.

Conclude with the correct answer: The cornea is the transparent extension of the sclera that lies in front of the pupil, allowing light to enter the eye.
