One summer day, at home, I was attentively listening, out of doors, to a conversation between two men, both past middle life and about the same age, one an educated Englishman, wearing spectacles, the other a native, who was very impressive in his manner, and was holding forth in a loud authoritative voice on a variety of subjects. All at once he fixed his eyes on the spectacles worn by the other, and, bursting into a laugh, cried out, "Why do you always wear those eye-hiding glasses straddled across your nose? Are they supposed to make a man look handsomer or wiser than his fellows, or do you, a sensible person, really believe that you can see better than another man because of them? If so, then all I can say is that it is a fable, a delusion; no man can believe such a thing." He was only expressing the feeling that all persons of his class, whose lives are passed in the semi-barbarous conditions of the gauchos on the pampas, experience at the sight of such artificial helps to vision as spectacles. They look through a pane of glass, and it makes the view no clearer, but rather dimmer--how can the two diminutive circular panes carried before the eyes produce any other effect? Besides, their sight as a rule is good when they are young, and as they progress in life they are not conscious of decadence in it; from infancy to old age the world looks, they imagine, the same; the grass as green, the sky as blue as ever, and the scarlet verbenas in the grass just as scarlet. The man lives in his sight; it is his life; he speaks of the loss of it as a calamity great as the loss of reason. To see spectacles amuses and irritates him at the same time; he has the monkey's impulse to snatch the idle things from his fellow's nose; for not only is it useless to the wearer, and a sham, but it is annoying to others, who do not like to look at a man and not properly see his eyes and the thought that is in them. To the mocking speech he had made, the other good humoredly replied that he had worn glasses for twenty years, that not only did they enable him to see much better than he could without them, but they had preserved his sight from further decadence. Not satisfied with defending himself against the charge of being a fantastical person for wearing glasses, he in his turn attacked the mocker. "How do you know," he said, "that your own eyesight has not degenerated with time? You can only ascertain that by trying on a number of glasses suited to a variety of sights, all in some degree defective. A score of men with defective sight may be together, and in no two will the sight be the same. You must try on spectacles, as you try on boots, until you find a pair to fit you. You may try mine, if you like; our years are the same, and it is just possible that our eyes may be in the same condition."
