I don't have any personal experience with one-eyed horses at all, but I do have experience with a one-eyed dog, as well as hearing what others have said about their one-eyed horses.
My grandparents, who house my horse (but not me, just to clear things up), have a dog named Patch who has only one eye. Our vet thinks he was born like that, but there's really no telling. He showed up with his eye already gone, as a stray, and my grandparents took him in. The vet decided we didn't need to have the eyelids stitched shut, since it was just the clean socket, and wasn't infected or anything of the sort, unless it bothered us, and it didn't.
Patch lives a perfectly normal life. The only thing that I have noticed about him that is different than other dogs is that he trots and runs sort of sideways. I think he does it so that the eye he has will be in the front where he can see well.
He runs and plays with his friends Otis and Bolt on a frequent basis, and has captured many squirrels and rabbits (I'm not proud of that, but that was to show you how well he adjusted).
Now I will tell you from what I've heard about horse owners with horses with one eye. I haven't heard of many one-eyed horses that couldn't be ridden anymore. I do imagine that they could suddenly go spooky, but I would think you could still show and have fun.
Combining what I know from personal experience with a one-eyed dog and what I've heard from others about one-eyed horses, I'd say that you'd likely be just fine with a one-eyed horse, and just to be careful around her blind side. She might start being spookier, but hopefully, since it is a slowly-progressing blindness, she will slowly adapt to having one eye and it won't be all too hard on her. She may turn her head to look around while you're riding so she can see, but that's okay. I think her quality of life should be very good. I hope it turns out for the best. I hate to hear that she's going blind, but my grandparents ALSO owned a dog who went completely blind in his later years, and he was a jolly old fellow, and got around just fine!
