@Shinegreymon96,

Yep! Magical prosthetic eyes! What nopony was expecting was that, over the centuries, the magic that created the eyes replaced more the rest of the organic components of their bodies in each generation until, by Sombra's day, a Crystal Pony was a bio-mechanism, a silicon crystal-based life-form whose various components perfectly mimicked their biological equivalents.

So, yeah, in my headcanon, they're sort of cyberponies but without the "no emotions" and "upgrade the universe" issues.
