What is the bending of light as it passes through a lens that allows a focused image to form on the retina?

Explanation:
Refraction is the bending of light as it enters a different medium with a different optical density. In the eye, the lens (and cornea) refracts light so that rays are bent to converge on the retina, forming a sharp focused image. Reflection would mean light bouncing off a surface, not forming a focused image through a lens. Diffraction involves bending around edges or through small openings and can blur details, while absorption means light energy is taken up by the material rather than directed to the retina. So the bending that enables the focused image is refraction.
