Hi there- this could be a lot of things! It could be that you need glasses or contacts. When your eyesight is bad, it can make your head and eyes hurt a lot. It could also be that you have chronic headaches, which is unfortunate, but usually not dangerous. There are many more reasons, but these are the most common ones. Your best bet is probably to talk to you parents or guardian, and see a doctor. They can tell you exactly what's wrong, and get it fixed up. Good luck!
