Blindness is mentioned in the Quran in these verses:

[22:46] Did they not roam the earth, then use their minds to understand, and use their ears to hear? Indeed, the real blindness is not the blindness of the eyes, but the blindness of the hearts inside the chests.

[41:17] As for Thamoud, we provided them with guidance, but they preferred blindness over guidance. Consequently, the disastrous and shameful retribution annihilated them, because of what they earned.
