What can be causing my headaches. i do wear glasses. i got my eyes checked and everything and im still having headaches?

Likely migraine: Although you may find it strange to have such bad migraines at such a young age, there are many migraine sufferers who have them younger. In cases like yours, patients are usually placed on a preventative agent taken daily to reduce the pain, and an acute agent (ie a triptan ie imitrex) to take when the headache comes. You likely also have rebound/medication overuse headache from the ibuprofen.

Not eyes: Most headaches are not caused by eye problems. In a 16 year old female, vascular headaches possibly related to hormonal changes are most likely, followed by stress headaches. You should have an exam by your medical doctor.
