Designed by Paul Fairbanks FSMCThe Rees-Fairbanks Facial Gauge has been designed to facilitate the selection, specification and final fitting of spectacle frames and mountings.
It was originally developed at City University with the teaching of ophthalmic dispensing in mind. Scales have been graduated in units that correspond with the accuracy required or attainable. The minimum graduation is in 2mm separations and the maximum is 5mm, this being sufficiently accurate for assessment of the head width. With this Rees-Fairbanks Facial Gauge you will be able to accurately measure the following:
Interpupillary distance
Distance between rims
Frontal angle
Head width
Temple width
Crest height
Apical radius
Distance between rims (DBR) at 10 or 15mm below crest
