Apparently St. Jerome (c. 340-420 AD) invented glasses as we know them, but the first refernces we have are set around the 14th century. The first medical reference is by Bernard Gordon, Professor of Montpellier (1305). He recommends a collyrium of such potency "that it will enable those whose sight is weak from old age to read without glasses."
