Helping a finch with vision issues?

[Featheredfuffs]

My little finch, Teena, has a tumor on the side of her face and it's affected her vision to the point where she can't really see. I've never had a vision affected bird before, how do I make her most comfortable? She's really old, so it seems like she's having a hard time adapting.

She will adapt, just dont move anything, since she already knows her setup. Only you know her, so watch her and make sure shes eating and drinking and not in any pain.
