What is the cause of pain at the back of my eyes?

Q: I have pain at the back of my eyes. Every time I move them they hurt. My eyesight is perfect and I don't have a headache and they are fine to look at the light. This has been happening for 3 days now and not getting any better. What is wrong with my eyes?

A:Pain behind your eyes without affecting your vision could be simple eye strain if you need glasses or could be due to sinus problem. Get yourself seen by an optician or eye specialist to get to the cause of this pain.
