Final answer:
The statement about reabsorption of the milky cortex is false; this does not accurately describe changes to the eye's lens or capsule. The ciliary muscles affect lens shape, and loss of these muscles' function can lead to hyperopia, which is corrected with a converging lens.
Step-by-step explanation:
The statement "Reabsorption of the milky cortex causes a reduction in lens volume, causing the capsule to form folds" is false. This statement does not succinctly represent a known biological or optical process related to the anatomy or physiology of the eye. Instead, age-related changes to the lens include hardening and loss of elasticity, leading to conditions such as presbyopia. Lenses can change shape through the action of the ciliary muscles, which alter their focal length to focus images on the retina.
When these muscles weaken, conditions such as hyperopia (far-sightedness) can occur where images are focused behind, rather than on, the retina. In such cases, a converging lens (or a plus lens) is needed to correct the vision so that light rays are properly focused onto the retina.
