<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, I have been experiencing facial pain and a foreign body sensation in my eye. Also, my vision has diminished. What could be wrong with me?  <response>: You may have a subconjunctival hemorrhage, which means there is bleeding underneath the conjunctiva in your eye. It can cause those symptoms, but it typically doesnt affect your vision for long.
