What controls the thickness of the lens to help focus light on the retina?

It is detected by the retina and 'thickness' varies as it is a reflex action; it cannot be controlled. Basically, 'you' cause it without knowing so.

The process of sharpening the focus of light on the retina is known as?
Contraction
Does light pass through the entire thickness of the neural layer of the retina to excite the photoreceptors?
true
Structure in eye which focus light by bending or changing thickness?
Both the cornea (hard outer tissue) and the lens (farther inside) curve light rays that fall on the outer eye and direct them toward the retina. The lens is adjusted by muscles in the eye, while the cornea has a fixed focus.
What controls the amount of light reaching the retina?
the iris controls the amount of light by limiting the volume of light admitted through the iris.
Which two structures are involved in bending light rays to focus them on the retina?
When bending light rays to focus them on the retina the two structure involved are the air-cornea interface which accounts for about two-thirds of the light-bending process and the lens which accounts for the remaining third but also makes the necessary adjustments to allow the eye to focus on objects at different distances.
Is it true that to focus light muscles in the eye change the length and thickness of the retina?
No, to focus ligh, muscles in the eye change the length and thickness of the lens.
Where does the light focus on the retina?
The Macula.
Bending light rays so that they focus on the retina is called?
The bending of light rays so they focus on the retina is called refraction.
Where does the lens on a pupil focus light?
Onto your retina. Onto your retina.
What part of eye focus's light?
the retina

What is the function of a len?
The lens bends the light rays to focus them on the retina.

Name the sequence of all the transparent materials in the human eye that light passes through on its way to the retina?
Lens, Cornea, Humerus focus light into the retina
