which headset do you have? the index is quite heavy, and if its not seated right, it does put a lot of pressure on your sinuses and forehead. It's never translated into eye pain for me, but your head might be weird like that. worth trying a few different positions to make sure. If the pain keeps happening reliably after 15 minutes though, you should probably ask an actual doctor. The only other thing I can think of besides the IPD is the fact that the headset is a fixed 2m focal distance. Could be that focusing that exact distance for 15 minutes makes your eyes hurt for some reason.
