Where on eye does light refraction occur?

Light refraction in the eye primarily occurs at the cornea, which is the transparent front part of the eye. The cornea has a curved shape and a higher refractive index than air, bending incoming light rays to help focus them onto the retina. Additional refraction occurs at the lens, which further fine-tunes the focus depending on the distance of the object being viewed. Together, these structures ensure that light is properly focused for clear vision.
