I know it likely is not related, but I flew on Friday and again On Sunday, about an hour each day, highest altitude was about 3000' AGL. This morning I woke up with the white part of my left eye red and very bloodshot to say the least. I do not have any conditions IE hypertension, Anemia, Diabetes etc. There is no pain and no vision impairment, so I am fairly certain it is nothing to be to concerned about. Just wondering if anyone else has ever had this and if flying could have contributed to it?
