TOS had another blind person (guest-starring) with a technological workaround (Miranda Jones, in the season 3 Is There In Truth Now Beauty? episode)- that was basically akin to sonar, making it impossible for her to pilot a starship, since she couldn't see things that were on viewscreens.

So there's already precedent for Geordi's situation.
