The human eye is one of the most amazing parts of our bodies. Our eyes can help us see, but they also help us to convey our emotions. People say that eyes are a window to the soul, but they are not just that. They are also the window that allows us to see the world. The (human eye) is strong yet delicate. It’s important to treasure your eyesight and do things to protect it. This can include eating a healthy diet, staying hydrated, wearing sunglasses if you’re outside in bright light, and using eye drops if needed to keep your eyes from being overly dry.
Parts of the Eye
The eyes sit in a group of bones that make up the eye socket, and muscles attach to our eyes here. These muscles attach to the sclera of our eyes, the outer layer, and this helps keep our eyes in place. The cornea, pupil, lens, and retina are some of the most well-known parts of the human eye. The clear part of the front of your eye is your cornea, and this is the part that initially focuses light coming into the eye. The amount of light that is let in is controlled by the pupil, like the shutter of a camera. The pupil changes size depending on how bright the light is around you; if you pay attention, you will notice that your pupils are much smaller when you are in bright light. Surrounding your pupil is the colored part of your eye, which is your iris. The lens focuses the light that comes in onto the retina; the retina is in the back of the eye so it can more easily send information to the brain.

The Eyes and the Brain
Different parts of the human eye regulate the amount of light that’s let into your eye, focus the image, and then send this image to the retina. The retina communicates with the brain, and the brain converts this information into an image in our mind. The brain is constantly being sent new visual information, which the brain interprets and sometimes stores away as memories.

How Do We See Color?
When light waves hit an object, some of the light will be reflected toward your eye, while other parts of the light will be absorbed by the object. The light waves that are reflected travel to the cones, which are located in the back of your eyes, within the retina. We have millions of cones in our eyes, and they respond to different colors of light. When a light wave enters the eye and travels to the retina, the cones that activate send signals to our brain, which translates these signals to tell us what color we’re seeing. There are many different colors, and although we can see a wide range of them, some animals can see more colors than we can: For instance, some animals can see ultraviolet light, which is beyond the deepest purple we can see on the spectrum.

How Do We Get Our Eye Color?
Eye color is genetic, meaning that we inherit it from our parents, but it’s not as simple as people once thought. We used to think that there were usually just two genes: either a blue-eye gene or a brown-eye gene. But now, we know that at least eight different genes play a role in determining our eye color.
