They pull the lens to make it long and thin.

How does light travel through the retina and explain how light is focused for distant and close vision?
light is focused onto the retina, which is made up of light sensitive cells called rods and cones. THey detect this incident light energy and then convert it into signals, which are sent to the brain. In order to focus on near or far objects, the lens in our eyes is suspended my ciliary muscles. when we focus on something far away, they pull the lens flat as the light has more time to bend, do doesn't need to be bent as much. Therefore, with objects upclose, the muscles cause the lens to relax and become fatter, bending the light drastically to focus the image
How does the lenses in your eyes adjust to focus on near and distance objects?
The first lens, the cornea, has a power of 60 diopters. This is constant, it can not change. The second lens, directly behind the cornea, is the one that is responsible for adjusting focus. This lens' shape is changed by muscles in the eye. It has a zero to 4 diopter range. At zero, when the muscles are relaxed, the eye is focused on infinity. When it is "flexed" to it's maximum of four, the eye should be able to focus on something that is at least 25cm away.
What does it mean to say that the planets revolve in an elliptical orbit with the sun at one focus?
that it will be faster when closer to the sun than futher away
Do you use a dark or light color to make something in a picture look farther away?
Dark
Using the Doppler effect astronomers can determine a stars what?
How close and far something is from you.
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.
What happens when you look at an object that is far away?
Focal length of eye lens increases and the ciliary muscles expands
When the eye is looking at objects far in distance the lens is rounded and the ciliary muscle is contracted?
The ciliary muscle is relaxed when you look at something that is far away.

Which eye parts helps eye to adjust the focal length of the eye lens?
The ciliary muscles which relax to help the eye see far away by expanding and pulling the lens and stretching it and contract to scrunch the lens up and see close up. By shrinking the lens, they allow it to bend light at a more drastic angle to focus on close up images.
What type of lens is the lens of your eye?
The lens in the human eye is a convex lens, but it is flexible and when it is acted on by the ciliary muscle around it, the lens can be "flattened" to change the focus, or, when the muscle is relaxed, the lens can assume a more spherical shape. This is at the heart of the ability of the eye to focus on objects nearer or farther away.

What does the lens in your eyes have to do to keep something in sharp focus while its moving away?
nothing

It means instead of enjoying something, you focus on the little details.

What are the similarities of the human eye and the camera?
Well, one thing is focus. When you look at something far away, notice that anything close becomes blurry? And when you look at something close, that anything far away becomes blurry too. This is because your eyes are focusing, and that's basically what a camera does, is focus.
How the eyes can maintain its focus when the object is farther or closer to the eye?
For near objects, the ciliary muscles will contracts causing the zonular fibers to relax which causes the lens to become rounder which shortens the focal length allowing the objects to be seen up close. For distance objects: the ciliary muscles will relax causing the zonular fibers to tighten which causes the lens to be flatten which lengthen the focal length allowing the objects to be seen at a distance.
