Yes the lens focuses the light to the back of the eye, the retina, which has rods and cones. rods-sharpness and grayscale and cones-color.
The coarse-adjustment knob moves the body tube up and down to allow focusing of the image.

The retina in the back of your eye contains rods and cones. Rods allow us to differentiate between black and white, or light and dark. Cones allow us to distinguish between colors. The periphery of our vision is composed mainly of rods and the central part of out vision is composed mainly of cones. The fovea is a small indentation in the retina, directly in the center of our vision. It is composed of only densely packed cones. This is the reason why we often have a hard time seeing something in the dark unless we look slightly away from it.

Ladders can absolutely function as staircases. In many design magazines, it has become a chic idea to allow a ladder to stand in for a set of stairs.
True.
The function of the lens of our eyes:To reflect the light and then you see that the black and white sclera protecs the iris with the cornea and with the macula on the helping optic nerve.
Rods
If a body detective comes across a bunch of cones it means she is exploring the eye. In particular, the retina of the eye. Their function is to allow us to see in color.
These nerve cells are called rods.
Light travels through the pupil to the cones, which lie on the inside of the eye. It is these photoreceptors that allow the perception of color.

It doesn't. Vision is a function of light passing through the pupil of the eye to the retina, with impulses then sent to the occipital cortex where the brain processes the information in order to allow an image to be perceived.
A Basketball's function is rooted in the game of basketball. It's function is to allow one to play basketball.
The refraction of light by the cornea and lens of the eye makes it possible for an image to form on the retina. Without the formation of an image, it would be possible for the retina to detect the presence or absence of light, but not shapes or objects.
Located in the retina (back of the eye) rods allow you see shades of black and grey cones allow you to see colors
