Product Number: 16127
Distometer

Purchase Gulden's Distometer.  This product is used to accurately measures the vertex distance between a patient’s cornea and the lenses in eyeglasses or trial lenses.  It is sold in a case with a conversion wheel for calculating lens power relative to the distance from the eye.

$99.00

A change in vertex distance of eyeglasses compared to that of the trial lenses results in a change in the effective power of the eyeglasses. This becomes especially important when the eyeglass prescription is greater than a plus/minus four or five diopter correction.

Use this tool to measure distance from the patient's cornea to the lens of glasses or trial lenses in a trial frame.  A circular conversion calculator is included with each distometer instrument.  The distometer features a durable metal construction.  Comes in a case.
