The Fairbanks Datum Rule, designed by Paul Fairbanks FSMC, is an essential tool for students and professionals in the fields of Dispensing Optics and Optometry

This gauge is used to measure various critical dimensions of optical frames, ensuring precise fitting and alignment for optimal visual performance.

The Fairbanks Datum Rule measures several key parameters, including the distance between lenses (DBL), bridge width, geometrical inset, bridge height, boxed lens size, front angle of pad, and angle of side

These measurements are crucial for accurately fitting lenses into frames and ensuring that the frames sit comfortably and correctly on the patient’s face

One of the significant features of the Fairbanks Datum Rule is its ability to measure the horizontal datum length, which is always recorded first

This measurement, along with the mid-datum depth, helps in determining the precise positioning of lenses within the frame

The rule also includes scales for measuring other linear and angular surface dimensions, making it a comprehensive tool for optical measurements

The Fairbanks Datum Rule is indispensable for students learning the intricacies of optical dispensing and for professionals who require precise measurements in their daily practice

Its robust design and accuracy make it a reliable tool that can be used throughout one’s professional life

For those looking to enhance their optical measurement capabilities, the Fairbanks Datum Rule is a valuable addition to their toolkit.
