Eye movements

Your eyes are like two little cameras that let you see the world around you. But just like how a camera can move its lens to get a better picture, your eyes can also move around to see things better. Eye movements happen when different parts of your eye work together to look at different things, like when you look up, down, or side to side.

Your eye has six muscles that work together to move your eye around. These muscles work like a team to make sure your eye moves smoothly and accurately. They also help your eye stay still when you want to have a good look at something.

When you move your eye, your brain gets a signal to tell it where to look. Your brain then tells your eye muscles how to move so that you can look at that thing. Your brain also helps you make very small eye movements that are called micro-saccades. These tiny movements help keep your eye focused on whichever object you are looking at.

Eye movements also help you read. When you read, your eyes make small jumps from one word to the next. This is called a saccade. Your eyes also spend some time staying still on each word so that you can read it clearly. When you finish reading one line, your eyes will move down to the next line using a bigger movement called a jump.

Overall, eye movements help your eyes work together to see what you want to see. They help you look at things smoothly and accurately, so you can understand the world around you.
