A new Lensmeter model CP-1B.This device is used by optometrists and opticians. Another type is with printer.

   This device called Lensmeter or Focimeter is a special tool used for measuring the power of a spectacle lens. The CP-1B is a manual type of Lensmeter and because of this, there is a specific way of how it should be used. The target that is usually a crossed set of combined lines is imaged through a lens of focal length. At the rear focal point of the lens we place the spectacle lens that we want to test. It is very important that the spectacle lens is placed correctly, so do not be hasty when doing this but make sure that you have done everything right. If you want to understand how to read the glasses, you must understand the number line. The number line spreads at both sides, divided with 20 diopters at each side. On one side are the positive values while on the other side are the negative ones. Adjusting the eyepiece for your eye is important in order to ensure the correct measurement. Turn on the device without any glasses put In, and look in to the eyepiece. Turn the eyepiece towards plus until the cross hair becomes blurry, then turn the eyepiece towards minus until the cross hair comes into focus and then stop. Once you have done this, you are ready to go.
