Description
This is a simulation to illustrate the processes involved in the formation of images in plane mirrors. When the control points are visible, you can move the object (the blue arrow), the four points where the (blue) incident rays strike the mirror, as well as the two ends of the mirror itself. The diagram shows two real rays coming from both the top and bottom of the object. The green rays show where the diverging real reflected rays go, and the red dotted rays show the virtual rays which converge to form the virtual image behind the mirror.

Description
This is a simulation demonstrating the optics of the human eye. It also shows how various lenses can be used to correct for faulty vision. Be aware that it is a simplified version of what actually happens. In the simulation, there is no bending when light moves from the air into the eye (when most of the actual bending happens). Instead, in the simulation only the bendings that happen in the lens of the eye (or in the corrective lenses) is shown.

Move the object closer to or farther from the eye (drag the object or use the Object Position slider). Use the focus slider to change the shape of the lens of the eye to adjust its focal length. When the refracted rays in the eye come together on the retina, the image is in focus. In some special cases you have the option to see how corrective eyewear can be used to overcome vision problems like nearsightedness and farsightedness. Adjust the Overlay Eye Anatomy slider to see a detailed image of the anatomy of the eye.

Some Questions:
What is different about the rays of light that reach the eye from an object near the eye, as compared to rays that come from an object far from the eye?
What is nearsightedness? In nearsightedness, what is the issue with the lens? What type of lens can correct for this?
What is farsightedness? In farsightedness, what is the issue with the lens? What type of lens can correct for this?
What about a person that needs bi-focals? What is the issue with the lens? What type of lens can correct for this?

Even if the object does not shine by itself, why can we see it?

Eye is the organ that feels light. Even if the object does not shine by itself, why can we see it?
Most objects can reflect light without emitting light themselves. Light reflected from rough surfaces such as paper or wood is scattered in many directions. The eyes recognize this diffuse light. Therefore, people can see objects with a little light.

Focusing

To view objects in detail, the light originating from one point on the object must be accurately gathered at one point on the retina. If the lights are scattered all over the retina, we will lost the focus.

In order to gather the emitted light into one point of the retina, there must be a device that acts as a convex lens. This is the cornea and lens of the eye.

As light rays reflect off of an object such as a tree, some of the rays travel to the eye. Rays of light enter the eye through an aperture called the pupil, the dark spot in the center of the eye. Surrounding the pupil is a colored ring called the iris, which opens and closes, controlling the size of the pupil and thereby the amount of light that enters the eye. Covering the pupil is a layer of transparent tissue called the cornea, and behind the pupil is another transparent tissue called the lens. Together the cornea and the lens focus the light entering the eye by bending, or refracting, the rays of light entering the eye. Muscles surrounding the eye change the shape of the eye slightly to focus the eye, similar to the way a telescope works. When everything works properly, an image forms on the tissue of the back inner wall of the eye. This tissue is known as the retina, and it contains light-sensitive cells known as rods and cones. The rods and cones process the light from the image projected on the retina into a signal that is carried by the optic nerve to the back of the skull, where the visual center of the brain turns that information into the images we perceive as sight.

Sometimes small deformities in a person's eye can interfere with the eye's ability to focus light correctly on the retina. Corrective lenses can sometimes help people with vision problems see more clearly. A positive lens may be used.

Focusing

The light started from the object must have arrived exactly at one point on the retina to see things in detail. On the other hand, if the light from one point of the object is scattered all over the retina, we will perceive things faintly.
Therefore, a convex lens is needed to collect the light emitted from the object into a retina point. This is the cornea and lens of the eye.

Vision correction

If the light is not refracted as you want, it will cause problems with vision. In this case, you can calibrate in various ways.

Near-sightedness: It is the case that the focus is excessively refracted, and the focus is formed in front of the retina. It isn't easy to focus on a distant object. You can calibrate it with a concave lens.

Far-sightedness: Light is not refracting enough. So the focus is behind the retina. It isn't easy to focus on the near object. You can calibrate it with a convex lens.

LASIK LASEK Surgery: There is also a correction method through surgery. For vision correction, cut out the cornea surface or the inside of the cornea. It has the advantage of semi-permanent correction. However, since it is necessary to shave the cornea, surgery may not be possible. (The cornea is too thin or many other reasons)

Focus adjustment of the camera

The eye focuses by adjusting the thickness of the lens.
On the other hand, the camera focuses by adjusting the position of the lens.
