The pain in the eye can be due to ocular or ophthalmic migraine, glaucoma, stye, sinusitis, eye infections, eye strain as is seen in refractive errors (if you cannot see properly and need spectacles). It is very difficult to diagnose the cause on net. Depending on other symptoms, tests, and clinical examination, a diagnosis can be made. Please consult an eye specialist.
Take care!
