I have a large dark bluish/greyish vein in my eye socket going from the corner of the cavity all the way to my eye. My eye has been in pain for the past few days and I thought it was due to strain from looking at the computer monitor. Would not be the first time that has happened as I spend a lot of my time looking at computer monitors. I will post a picture and I hope it will be of good enough quality to help determine what is going on. Any help or suggestions would be appreciated. Thank you.
