Loupe Fitting Guide

To complete your order your customized Dental, Surgical, Dental Hygiene, or Veterinary Loupes - we need your fitting measurements.  These can include working distance (WD) and Pupillary Distance (PD). 


First, you have a choice of loupe type you wish to purchase - either Customized Through-The-Lens (TTL) Loupes or Adjustable Flip-Up or Clip-On Loupes:

Comparison of Surgical & Dental Loupe Magnification Levels 2.5x 3.0x 3.3x & EDGE

SheerVision recommends a 2.5x level of loupe magnification for dentists, and also for most first-time loupe wearers.  Going beyond to a 3.0x or 3.3x will increase the level of magnification – but with a reduction in the field of view.  With a 2.5x loupe will allow you to see the entire arch of the mouth – rather than just a few teeth. Note how as the magnification level increases the field-of-view decreases in this image.


Third, for all of our loupes we need to get your working distance (WD) measurement. This will insure that the loupes are focused to align with the way you like to practice.  
Loupe Working Distance Measurement Example - Hygienist & Dentist

Working distance varies by height and body type, but also how you sit and work with your patients. The best method is to use a tape measure, or similar measuring device. If you are a dentist, dental hygienist, or dental veterinarian  (or any practitioner who sits) - while sitting in an ergonomic position in your normal workspace, measure the distance between your eyes and the patient’s teeth.  This is your specific working distance. Please note that for SheerVision 2.5x magnification that our innovative optical design will provide 5-6” (125-150mm) depth-of-field, which means you will be able to move your head closer and farther from the patient – without a loss of focus. 


Fourth, to customize the TTL (Through-The-Lens) loupes to match your personal traits, we will need your pupillary distance (PD) measurement.  It is just a measurement of the distance between your pupils:

Loupe - Pupillary Distance Measurement

The PD can be measured by any local optician (Costco, Target, Wal-Mart, etc) by using a device as shown - normally for no charge when you tell them you need your PD to order surgical / dental loupes.

With SheerVision, you have a choice of frame for both TTL & Flip-Up loupes. We are the exclusive provider of loupes with Under Armour Brand Frames . SheerVision also offers its own frame models including the Performance Titanium, and Del Rey Models. Note that some of our frames specifically work for TTL or for Flip-Up Loupes.  


Wear glasses? Need vision correction? No problem.

Normally, if you wear prescription glasses while you work then you will most likely need to have prescription lenses added to your loupes.

SheerVision is happy to assist you with your prescription needs as many doctors and hygienists require that their eyeglass prescription be fitted to their loupe system.

We offer these prescription options:
- Flip-Up Loupe Frame Only (Flip-Up & TTL Loupes) - Provides Distance & Near Correction
