Answer 1

From the Bible (Acts 9:18)

American Standard Version

And straightway there fell from his eyes as it were scales, and he received his sight; and he arose and was baptized;

Scales in his case means those little plates on the skin of fish or insects.  Something like repairing cataracts that old people get.
