Augustine of Hippo : BLINDNESS OF THE SODOMITES — And they smote the men that were at the door of the house with blindness . The Seventy use the word aorasia , which properly means, if it can be said so, an invisibility that does not entail a total loss of vision, but only obscures what is not necessary to see. For this reason, it would cause us peculiarity that they might faint for the door, had they been punished with such blindness as to prevent them from seeing. In this case, troubled by their calamity, they would have stopped looking for the door. With this same aorasía was also punishment for those who looked for Elisha (Cf. 2 Kings 6:18). And this same blindness also had those who, walking with the Lord, (Cf. Lk. 24:16) after his resurrection, did not recognize him on the road, although there is no mention of this word, but the same thing. [ — QUESTIONS ON GENESIS, Q. 42 (tr. J. Litteral, draft)
