What Should I Do About My Headache and New Glasses?

I always get headaches for the first few days of having new glasses. They told me it's just your eye getting used to the new prescription

Hi arty, if glasses don’t help the headaches maybe there’s another reason you’re having them or maybe the glasses don’t fit.. there could be like a million reasons for headaches.. I guess tension headaches are the most common ones where the pain could feel like a band around the forehead
