Amblyopia, also known as lazy eye, happens when one of your eyes doesn't work as well as it should. This can happen if you use one eye more than the other or if one eye is not able to see very well. Your brain relies on both eyes to see things clearly, but if one is not working right, your brain might ignore or "turn off" that eye.
This can cause some problems with your vision, making it tough to see things that are far away, like letters on a chalkboard, or things that are close up, like your toys.
But don't worry, there are ways to help fix lazy eye. Sometimes, wearing an eye patch over your good eye can help your weaker eye get stronger. Other times, special vision therapy can help train your eyes to work better together.
It's important to take care of your eyes so they can keep working well for you!
