Which transparent layer forms the front of the eye and allows light to enter?

Explanation:
The cornea is the transparent front layer of the eye that lets light in and begins to focus it as it enters. Its clear, curved surface allows light to pass through without distortion and helps bend (refract) light toward the retina, contributing significantly to the eye’s focusing power. The other options aren’t part of the eye’s front surface: the endometrium lines the uterus, the placenta nourishes a developing fetus, and an oocyte is an egg cell produced by the ovary. So the cornea best fits the description of the transparent front layer through which light enters.
