Yes, she will adapt to one eye in a few weeks. The same happened to a ewe of mine and she reared several more sets of twins.
Urgently she needs antiBs, pain killers, and for the eye to be covered. Use vaseline gauze or similar which will not stick badly, then thick padding, held in place with a conforming bandage (vet has them). In the case of my ewe, the eye eventually dried up and disappeared, but the socket stayed open. This is a route directly to the brain so potentially dangerous.
When this happened to my ewe, F & M had just been declared and we were cut off by massive snowdrifts. The vet gave me instructions over the phone and I had most of the stuff needed in my first aid boxes - sheep and human. My ewe was in obvious pain, grunting and grinding her teeth, but as soon as the eye was covered she was more comfortable. I stayed and cuddled her for ages. Initially she kept bumping into things which were on that side of her, hence the thick padding, but she soon learnt. I kept her indoors (well, in a horse box outside) until she was past the worst. The other sheep would come and visit her so she had company.
