The eyes of many people are ruined because, instead of going to an oculist to have their eyes properly fitted to glasses, they go into a ten-and-fifteen-cent store, try on a lot of cheap glasses, and purchase the ones that magnify the best, and feel most comfortable on the nose. The cheap varieties of glasses are often made from bits discarded by opticians, and never intended to be used again.
His explanations were simple. He used no mathematics. He was the Master Experimenter. I don't think there were many copies of Faraday's works sold in those days. The only people who did anything in electricity were the telegraphers and the opticians making simple school apparatus to demonstrate the principles."
Some months earlier that is to say, about six months after Jack's departure Sir John had called casually upon an optician. He stood upright by the counter, and frowned down on a mild-looking man who wore the strongest spectacles made, as if in advertisement of his own wares. "They tell me," he said, "that you opticians make glasses now which are calculated to save the sight in old age."
But my German mirrors reflect without prejudice, selection, or comment; and the American eye, I fear, is but mortal, and like all mortal eyes, figuratively as well as in that literal fact noted by an eminent scientific authority, infinitely inferior to the work of the best German opticians.
"Think we shall polish out all the scratchings?" "Why, they are gone now," cried Tom. "Yes, it shows what patience will do," said Uncle Richard; "a man can't lift a house all at once, but he could do it a brick at a time." The speculum was carefully placed aside after its cleansing, and the pair of amateur opticians locked up the place after hanging up their aprons.
Optical tests can be conducted by securing an ordinary letter chart such as is used by oculists and opticians. Seat the subject twenty feet away. If he can read all the lines of letters from the largest down to the smallest his eyesight is practically perfect. In a large percentage of cases the smaller lines of type are blurred and invisible.
All that method could do had been accomplished by Bichat and his followers. It was for the optician to take the next step. The future of anatomy and physiology, as an enthusiastic micrologist of the time said, was in the hands of Messrs. Schieck and Pistor, famous opticians of Berlin. In those earlier days of which I am speaking, all the points of minute anatomy were involved in obscurity.

There was an old Greek Testament and the Eton Latin Grammar; a French pamphlet on the cavalry sword-exercise; an odd volume of Tom Jones with one half of its stiff leather cover hanging to it by a thread; Byron's Don Juan, printed in a murderous type, which must have been invented for the special advantage of oculists and opticians; and a fat book in a faded gilt and crimson cover.
Whatever my own optical skill could suggest, I tried; and the best opticians were sent for to bring their glasses, and take his directions for altering them; but all was to no purpose. In this last year of his life Kant very unwillingly received the visits of strangers; and, unless under particular circumstances, wholly declined them.
