Can someone please explain to me what’s going on with my eyes?

This have been going on for months now, but only recently have it been starting to hurt. I’ve been told I could be at risk for glaucoma. I’m gonna go to the doctor soon, but I wanted to see if i can get any input on what it may exactly be or why it’s happening before hand. Thanks
