The short answer (excluding the seeing part, because being completely blind necessarily means you do not have eyesight): yes.
The long answer:
Disabled people can and do function as well as able people. Sure, the blindness means there are certain things they can't do (e.g. read, watch a silent movie), and some things they may take longer to learn due to the lack of visual cues. But people are notoriously adaptable. Some blind folks can do something called human echolocation by, for instance, clicking their tongues. It's like a sonar. It lets them get around without running into things. It lets them do things like play basketball, or other sports. I suggest watching the Paralympics to see how much people with disabilities, even severe ones, are capable of.
I mean, sure, a blind person can't read (with their eyes). But can you close your eyes and find your way around just by clicking your tongue? Functioning 'well' is relative (and honestly, the notion that having a disability means you function less well than someone without it is ableist; I'd say the distinction is functioning differently, rather than more or less well).
But the answer you're probably looking for: No, there isn't much of a point to having your character be disabled if the disability never factors into it.
But it's not the case here, really.
