The ability of the lens to bend light rays so they focus on the retina is known as

Answer 1

The bending of light rays by the lens to focus on the retina is known as refraction. This focusing ability can diminish with age, leading to presbyopia, whereas myopia results from an elongated eyeball.

Step-by-step explanation:

The ability of the lens to bend light rays so that they focus on the retina is known as refraction. The lens of the eye is flexible and operated by surrounding muscles, allowing it to change shape to focus light sharply on the retina, which is necessary for producing clear images of both near and far objects. However, as we age, the lens loses its flexibility, leading to conditions such as presbyopia, where the lens can no longer focus on nearby objects, causing them to appear blurry. On the other hand, myopia (nearsightedness) occurs when an elongated eyeball causes the focal point to fall in front of the retina, making distant objects appear blurry.

Answer 2

The power of the lens of an eye adjust or bends the light rays to provide an image on the retina depending on distance of the object.

Step-by-step explanation:

The lens of an eye and the cornea work together in forming a real image in the retina that houses numerous receptors in the fovea and blind spot of the optic nerve.

Image will be formed in the retina when light rays converging most at the cornea upon entering and exiting the lens.The power of adjusting the eyes focal length is known as accommodation.
