The 5 senses allow humans to gather data about the world we live in. This data makes up our perception, and it dictates how we think and make decisions. The 5 senses include taste, smell, feel, sight, and hearing. Humans rely heavily on their sense of sight. Two hobbies of mine include astronomy and photography and the similarities between the eye and a camera are fascinating. There are also some interesting things I have learned about how the eye works in low light through astronomy that apply to what we have learned.
Our eyes pick up light on the visible spectrum. As light enters the eye it first passes through the cornea which is a clear covering that helps protect our eye and focus the incoming light. It then goes through the pupil which is a hole that can change size depending on how much light is present. The iris is the muscle that dictates how large the pupil is. After the light goes through the pupil it then passes through the lens. The lens focuses the light and it finally reaches the retina. The retina is filled with special neurons and cells that specialize in detecting light. Together these neurons and cells make up the optic nerve which ultimately sends information to the brain telling it what we see.
In many ways (but not all), this is how a camera works. Photography is all about how to get the proper amount of light to focus on what we want it to. In a camera, the light passes through the lens. 
The photographer can change how large or small the iris of the lens is. This is referred to as aperture. After passing through the lens it hits the sensor. In digital cameras, the sensor takes the light and converts it into bits of data and ultimately into an image that we can see.
The eye is similar to a wide angle lens with a small focal ratio. The eye can see a relatively large area; however, only a small portion of what we can see is in focus. The function of the retina is also very similar to an image sensor.
The human eye works slightly different when there is plenty of light verses when there is little light. As I mentioned before, the retina contains optic nerves. These are composed of cells called rods and cones. Cones are the cells that detect detail and color; however, they work best when there is plenty of light. Cones are concentrated in the center of the retina. Rods on the other hand are not as good at detecting detail and color, but they are more sensitive to light. Rods are more evenly spaced out throughout the retina and most highly concentrated slightly off the center of the eye.
Rods come in handy when observing the stars. Some objects are extremely faint, and when you try to look directly at them they seem to disappear. When you look just to the side of the object though, you can make out the 
object in your peripheral vision. This is because your rods are more concentrated in this part of your eye and are better at detecting light. This method is called “averted vision”.
Vision is incredibly important to the way we perceive the world. The way our eyes take in light is fascinating and valuable to understand in order to make sure we can appropriately analyze our surroundings.
