The ability of the eyes to focus on both near and distance objects is termed

The ability of the eyes to focus on both near and distant objects is called accommodation. Accommodation is the process by which the eyes adjust their focus to allow us to see objects clearly, whether they are close or far away. This is achieved through the action of the ciliary muscles and the crystalline lens inside the eye. When we look at a nearby object, the ciliary muscles contract, causing the lens to become thicker and more curved. This change in shape helps to bring the image of the object into focus on the retina. When we look at a distant object, the ciliary muscles relax, causing the lens to become flatter, which helps to focus the image of the distant object onto the retina. Image formation, refraction, and hypermetropia are related to the function of the eye, but they are not the same as accommodation. Image formation refers to the process by which light is transformed into an electrical signal that can be interpreted by the brain. Refraction refers to the bending of light as it passes through the cornea and lens to form an image on the retina. Hypermetropia is a type of refractive error in which the eye has difficulty focusing on nearby objects.
