When the ciliary muscles view a distant object, they relax. This causes the suspensory ligaments to pull tight, which flattens the lens of the eye. As a result, the eye is able to focus on the distant object by decreasing its refractive power.
The object pulled on by ciliary muscles to bend light is the lens of the eye. The ciliary muscles change the shape of the lens, which allows the eye to focus on objects at different distances.
When viewing a distant object, the ciliary muscles in the eye relax, causing the lens to flatten. This allows the lens to focus the incoming light rays from the distant object onto the retina for a clear image to be formed.
When shifting focus from a distant object to a nearby object, the lens focal length increases to bring the nearby object into focus. This adjustment allows the lens to refract light rays at different angles to converge at the sensor or film plane, producing a sharp image of the nearby object.
When you look at an object that is far away, the light rays reflecting off the object appear more parallel by the time they reach your eyes. This causes the lens in your eye to flatten, which helps focus the image on the retina. Your brain then processes this information to perceive the distant object as smaller and potentially less detailed compared to closer objects.
The ciliary muscles contract to shape the lens in the eye, making it rounder and thicker. This change in lens shape enhances its refractive power, allowing the eye to bring near objects into focus.

When looking at a distant object, the ciliary muscles in the eye relax, causing the lens to flatten. This allows the light rays from the distant object to focus directly on the retina at the back of the eye, creating a clear image.
When viewing a distant object, the ciliary muscles in the eye relax, causing the lens to flatten. This allows the lens to focus the incoming light rays from the distant object onto the retina for a clear image to be formed.
When you look at a nearby object, the ciliary muscles in your eye contract, causing the lens to become thicker and rounder. This helps to increase the refractive power of the lens, allowing you to focus on the nearby object. When you then look at a distant object, the ciliary muscles relax, causing the lens to become thinner and flatter, decreasing its refractive power and allowing you to focus on the distant object.
When shifting focus from a distant object to a nearby object, the lens focal length increases to bring the nearby object into focus. This adjustment allows the lens to refract light rays at different angles to converge at the sensor or film plane, producing a sharp image of the nearby object.
When you look at your wristwatch up close, the ciliary muscles in your eyes contract, causing the lenses to thicken and focus on the nearby object. When you shift your gaze to a distant mountain, the ciliary muscles relax, allowing the lenses to flatten out and focus on the faraway object. This process is known as accommodation, where the shape of the lenses change to focus on objects at different distances.

Be sure not to confuse the roles of the ciliary muscles and pupillary muscles; this is a mistake that even the experts make at times. The ciliary muscles do not control the size of the pupils - this is the job of the sphincter pupillae and dilator pupillae. The ciliary muscles adjust the shape of the lenses in order to focus the eyes. They are attached to the zonules of Zinn, which are in turn attached to the lenses. Contraction of the ciliary muscles slackens the zonules so they don't pull so much on the lenses. The lenses become rounder, and the eyes can focus on a nearby object. When the ciliary muscles relax, the zonules pull the edges of the lenses so they become flatter and thinner for distance vision. This is the basic mechanism of accomodation. There is some disagreement regarding the details - look up Helmholtz and Schachar if you are interested.
If a person is looking at a near object. the cranial nerve tells the ciliary muscles to alter the focal distance of the eye. This causes nearer or farther images to come into focus on the retina. They call this process accommodation.
When you focus on a nearby object, your ciliary muscles contract to change the shape of the lens in your eye, allowing you to see the object clearly. This action pulling on the suspensory ligaments attached to the lens, causing them to relax.
The sequence of reactions when a person looks at a distant object is pupils dilate, ciliary zonule, becomes taut, and lenses become less convex. During embryonic development the lens of the eye forms from the surface ectoderm overlying the optic cup.
