Some have tried to show that blindness is a result of man's choice; but failed.
The whole of Scripture, and YHVH'S Plan for Salvation,
repeatedly and throughout all history shows that men are blind by default, as you put it.
What is the part in the religion that tries to show otherwise ? Why try ? It is part of a religious system that for some reason 'needs' men to only be blind by choice/disobedience, but that contradicts too much Scripture. All Scripture is true - Scripture does not contradict itself; or rather, God's Plan and God's Word is Perfect Forever , and His Plan as well, and there is no contradiction in nor from God,
so if anything or anyone contradicts God, it or them is not truthful nor from God.

We
grope like the blind along a wall,
groping like those who have no eyes; we stumble at noon as in the twilight, among the vigorous as though we were dead.
