How many megapixels is our eyes? – Learn Videography In 5 Days

When we are born, the eyes are about the same size and shape as an apple. As we grow, the eye changes shape and enlarges. We no longer see with the same visual acuity as we did 20 years ago, but we still see much the same.

In addition to the visual acuity that we possess (visual acuity is the perception of distance by the human visual system), a portion of the visual system is active in both sight and hearing.

When your retina absorbs incoming light, it uses its own energy in order to convert light in the visible spectrum—the visible light in sunlight and the ultraviolet or visible light in an enclosed space—into electrical impulses that go back into the retina. When the eye’s energy is used on both the visible and the ultraviolet spectrum, the visual acuity is very high. Your optical system is very precise and very capable in detecting small details and in reading distant objects—but your eyes cannot see much detail at a time. However, each small detail in the environment will only appear to be slightly different. It is these small details that make a detail visible or very clear. For example, you can see a bright star at night, but if a small piece of ice forms over a dark surface and falls onto it, it may not turn out to be the star at all. This small detail alone can make it possible for the retina to distinguish one small thing from an enormous amount of noise in the surroundings, and so you may see the detail of the star in the ice as the star at all. A similar example is the color of the snow; you can see it clearly when it is white on the snow surface, and you can see it differently on a white background. The color cannot be described with any detail, but is only one little part of the sky that can appear very different from the same background or on a white background.

When a certain portion of your eye is not active, it is not able to detect enough of a detail to make the object visible. Even tiny details that appear to be quite small to your human eye, such as small grains of sand or dust floating by or a dust bowl, can be a problem. However, the problem is less dramatic at a distance of 5ft than at a distance of 20ft, because you can see much larger particles of dust, grains of sand, or dirt at 5ft and only a smaller amount at 20ft.
