How to measure the correct working distance for your loupes ( TTLs or Flip Ups) is a question we are asked frequently at L.A. Lens. It is a measurement that is very simple and quick to take.
The working distance refers to the distance between the doctor's/ hygienist's eyes and the patients mouth. In order to measure this distance, you require two people, the user and the helper. The user needs to assume a normal working position, and needs to make sure that they do not lean forward too much when measuring. Then, the helper needs to place the edge of the tape measure on the bridge of the nose of the user and draw it downwards to the patients front teeth. This number will tell you whether the user needs a Short, Regular, Long or Extra-Long working distance in their pair of loupes. Please use the picture and chart below to help determine the correct working distance.
Taking your working distance measurement is one step in our guide to purchasing loupes, which can be found here.
