The ability of the human eye to focus images accurately on the retina is called accommodation. This is the process by which the lens of the eye changes shape to adjust the focal length of the eye and ensure that objects at different distances are focused correctly on the retina. When we look at a distant object, the ciliary muscles in the eye relax, making the lens thinner and flatter. When we look at a nearby object, the ciliary muscles contract, making the lens thicker and more curved. This change in the shape of the lens is what allows us to see objects at different distances clearly.
