What Causes severe eye ache?

Answer:
In my case it seems caused by not enough quality sleep for my body, that's when I usually suffer with it.
-----another reason may be dry eye. Artificial tears can be purchased OTC and could be one way to see if it is w/o going to the doctor. Systane or Refresh are the ones my clinic recommends everyday for this problem. Hope this helps!
