I think in technicallity, she is still "blind" in a sense. since her magic is to "see". it's a passive, but i wonder if she would loose it some how again. But yea i get you though it was a liiitle bit dissapointing that she could see again. I wished her girft would be an "upgrade" but litterally they gave her the "max upgrade" right away xD But im glad she can finally see her pretty world.
Most of those who are blind can still see, full blindness is very rare, it's more common for those who are blind to be partially blind. She is still blind, partially blind, she is just using other ways to see.
Technically from the beginning she could be considered partially blind because she was able to see to some extent because of magic. Then her blindness is fixed later on in the story, that's really disappointing for me and made this story go from 5/5 to 3/5.
