Contact lens

Contact lenses are special little circles that can go directly on your eyes to help you see better if you have trouble seeing things far away or up close. They are like glasses, but instead of sitting on your nose, they float on your eyes.

These lenses work by bending the light that comes into your eyes, which helps you see more clearly. They can be made for different eye shapes and sizes, so they can be customized just for you!

Before you can use contact lenses, your eyes need to be checked by a special eye doctor to make sure they are healthy and that the lenses will fit well. You also need to learn how to take care of them properly, which means cleaning them often and making sure they don't get damaged.

Contact lenses come in different types, such as soft or hard, and some can be worn for just one day while others can last for months. They can also be colored, so you can change the color of your eyes if you want to!

Overall, contact lenses are a great tool to help you see better, but you have to make sure you use them safely and take care of them properly.
