The Lensmeter is an optical instrument for determining the optical center and measuring the power (diopter) of an ophthalmic lens, as well as the direction of the cylinder. It has some nibs to mark the optical center and the direction of the axis.
A Lensometer is an optical instrument whose functionality is to inspect a lens to find out various properties associated with it, such as:
There are other names by which this device is known, such as lensmeter, focimeter, lentimeter or vertometer.
Thanks to this device, an ophthalmologist is able to measure the power of a lens when light rays strike its main axis in parallel, it also allows the verification and marking of optical lenses and contact lenses.
These are the most popular lensmeter and are used to learn how to work with measuring lenses.
In order to use them, you must first calibrate the lensometer manually by manipulating and adjusting its different parts, such as the eyepiece and the drum scale to 0, always seeking to obtain a clear view.
