What is the object pulled on by ciliary muscles to bend the light?
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.
What happens when the ciliary muscles view a distant object?
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.
How does the suspensory ligaments work to focus an image of a close object?
Suspensory ligaments are attached to the lens of the eye and can change the shape of the lens to help focus on close objects. When focusing on a close object, the ciliary muscles contract, which loosens the tension on the suspensory ligaments. This allows the lens to become more rounded, increasing its refractive power to focus the image on the retina.
What changes in your eye when you look at objects at different?
the lens is changed
What happens to the lens when it's looking close up?
When the lens is focused on a close-up object, the ciliary muscles contract to increase the curvature of the lens, allowing it to bend light rays more strongly and focus them onto the retina. This process is known as accommodation, and it enables us to see objects clearly at close distances.

How do the lenses in your eyes change shape when you first look at your wristwatch to read the time and then look at mountain in the distance?
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.

This allows the lens to become more rounded, increasing its refractive power to focus the image on the retina.
When an object is close to your eye what does the lens becomes thin or thick?
When an object is close to your eye, the lens becomes thicker. This is because the ciliary muscles surrounding the lens contract, allowing the lens to change its shape and increase its refractive power to focus on nearby objects.
What is the function of the ciliary in the eye?
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.
What is the process by which the lens of the eye changes its curvature?
The process by which the lens of the eye changes its curvature is called accommodation. This involves the ciliary muscles surrounding the lens contracting or relaxing to change the shape of the lens, allowing the eye to focus on objects at different distances.
What is the function of ciliary muscles?
The function of ciliary muscles is it controls the accomodation for viewing objects at varying distances and regulates the flow of aqueous humour into Schelm's canal. It changes the shape of the lens within the eye, not the size of the pupil which is carried out by the sphincter pupillae muscle. The muscle has parasympathetic and sympathetic innervation.

How does the lens in your eye change shape when you look at a nearby object then a distant object?
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.
What helps the lens change shape or focus on an object?
The ciliary muscles surrounding the lens help it change shape to focus on objects at different distances. This process is known as accommodation, where the curvature of the lens is adjusted to bring objects into focus on the retina.
