I'm so sorry to hear about your daughter's difficulties and her MG diagnosis. She might try taking a nap mid-day. This can help recover some muscle strength, including with the eye muscles. Another thing to try might be using ice packs on her eyes. The effect will be of limited duration, but they can help, too, particularly with ptosis (drooping eyelids). I've used the ice packs on my eyes sometimes in desperation. While the effect is temporary, it seems like it helps my eyelids stay up better for a little while, and I think that my eyes work better in general for maybe 20 minutes or more. Part of that might also be because I have closed my eyes while using the icepacks, which is also helpful, because it gives all of those muscles a chance to rest.

Sending lots of good wishes to you and your daughter - hang in there!

Take care,
