Edgar Rice Burroughs,
The Master Mind of Mars — Chapter II: THE HOUSE OF THE DEAD
(1928)
“ So startled was the old man by my agility that he jumped a bit himself, though doubtless involuntarily, but, however, with certain results. His spectacles tumbled from his nose to the sward, and then it was that I discovered that the pitiful old wretch was practically blind when deprived of these artificial aids to vision, for he got to his knees and commenced to grope frantically for the lost glasses, as though his very life depended upon finding them in the instant. ”
