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 Lensmeter 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 equipments are much easier to use since all the adjustment and calibration part of the lensometer to be able to analyze the lens is carried out automatically, throwing the values corresponding to the measurements that we want to control through a display.
Although automatic lensometers with different capacities and features are sold, the common point is that they have a screen with an LCD display that incorporates a large number of functions, such as graphics, a touch screen, ultra-fast measurement and, in some cases, a thermal printer. built-in.
