A childhood illness took her vision away. A later plot development would shed some more light to this (no pun intended). A close look in her eyes reveals that they're covered in cataracts.

When in combat, Stella uses her other senses to fight, in particular, she makes good use of her sense of sound to judge her opponent's position, and to aim and shoot at her opponents. Having been trained to gunslinging arts since she was a preteen, she has mastered the art of gunslinging even without her vision intact, and that's what makes her badass.

(An interesting sidenote is that blind marksmen actually do exist. Here's some proof. https://www.nydailynews.com/news/national/blind-sharpshooter-sound-aim-article-1.1351821?outputType=amp)
