. OPTICIAN GUIDANCE NOTES

The set of 

Riester

 surgical loupes have been supplied to your customer with Plano lenses fitted. We 

hope that the following notes on lens fitting and frame adjustments will help you, help your customer 
obtain the best from their loupes.

There are two types of binocular telescopes used in 

Riester

 loupes:

Galilean based on a Galilean optical system
Panoramic based on a Keplerian telescope system incorporating a roof prism.

Prescription fitting

First establish the following facts; -

1. The type of loupe (i.e. Galilean or Panoramic).
2. The magnification.
3. The working distance or focal length (noted on the loupes).
4. Your customers interpupillary distance, taking the working distance/ focal length of the loupe into 
consideration.

It is important to fit the frame as close as possible to the eyes so that your customer can obtain the 
widest field of view.

Any distance prescription should be fitted with centers to coincide with the loupe IPD setting.

If fitting bifocals, care should be taken to fit the bifocal segment either below or above the rim of the 
telescope (Fig 12) never in between. If the near vision ADD is more than +2D the bifocal segment 
should be fitted below the lower rim of the telescopes to avoid shortening the focal length of the 
telescopes and causing double vision.

Varifocals are not suitable for fitting to 

Riester

 loupes.
