It would probably be best to have yourself checked by specialists, namely an ophthalmologist and a neurologist, to undergo a more complete evaluation of your symptoms and clinical presentation.
There are many possible causes of your symptoms and this would include referred pain from the neck injury, nerve impingement, migraines, tension headache, sinus headache, glaucoma, etc. As such, it would be difficult to ascertain any of these until a proper examination is done.
Good luck.
