DR. M’LAUGHLIN’S INVENTION.

 

            The following editorial from the American Journal of Clinical Medicine, April, 1914, is a strong endorsement of the Opthalmo-Axonometer which was invented by Dr. McLaughlin of this city:

            “It is characteristic of all clever inventions that when one sees them for the first time one always wonders why he did not happen to think of the idea long ago. When first the writer was shown the Opthalmo-Axonometer a month or so ago, he spent the rest of the day figuratively kicking himself that he had never perceived the very simple and obvious principle on which it is constructed.  But next to inventing it himself, he appreciates the privilege of pointing out its merits.  As the advertisements say about another device, it is perfectly simple and simply perfect. It is the best thing in refraction since refraction became an applied science.  Briefly, it substitutes the focal length of the lens for the lens itself – which of course does away with all the cumbersome machinery of the trial-frame and the changing of lenses.  Instead of changing the lens before the patient’s eyes every time you want another dioptre more or less, you simply change the focal length by a sliding scale, which has precisely the same effect without any of the annoyance and friction.  And it has a lot of other advantages, too which cannot be told here. You positively must see about it.  We have just started in to tell our readers all about eye refraction, and to stimulate them to do the work.  Now, by a happy coincidence, this device comes on the market at the same moment, to simplify and guarantee the technique for you.  By all means write to the Standard Optical Co. of Waupaca, Wis., and find out about it.  It will increase your income several hundred dollars a year easily.”
