From the author POV,I would have to say that showing an eye to represent damage rather than blindness is more possible.

Meaning that I would have believed that Jellal was truly and completely blind if he hadn't opened and showed his eyes.

FT isn't that graphic when it comes to stuff like that. Them being damaged and Jellal opening them because of that is more likely.
