I am wearing glasses.my eyes pains and i get headache, i checked my eyes twice it match the power of glasses(checked by a contact shop not by a doctor.

Recheck: Go back to the prescribing eye doctor and have refraction rechecked and the fitting of your glasses analyzed. Often a cycloplegic refraction and ocular alignment assessment resolves the problems. The glasses may be too strong or astigmatism off axis or an undetected phoria that has decompensated to a tropia with the glasses. The latter two ideas would have double vision symptoms.
