ˈpresbyte
[ad. Gr. πρεσβύτης an old man (Aristotle, Prob. 31. 25). So F. presbyte, mod.L. presbyta.]
= presbyope.
(The modern use is not that of Aristotle, who only raises the question why an old man (πρεσβύτης) is long-sighted. Nor is it recognized even in the 1762 ed. of Castelli Lex. Med. I. Bywater.)
