In connection with this subject let me warn you of the existence of an
army of "Opticians." These men are often swindlers of the first water.
Their misrepresentations as to the money value of glasses amounts
to grand larceny. They charge all the way from ten to seventy-five
dollars for a pair of lenses that usually cost seventy-five cents
each. There are honest men in the business, but beware of the grafter.
There are many lesser lights engaged in the eye business, but the
examples given above will serve to place you on your guard. Take no
treatment by mail. Less can be done for the eye than any other organ
of the body, unless it is the ear. Both are so complex in their
anatomy and the symptoms so obscure that it is an impossibility to
make a correct diagnosis without seeing the patient and using the best
instruments that science can bring to the aid of the physician.
