CONTACT LENS DIAMETER GAUGE
Use this lens gauge to quickly check an RX received from the lab before dispensing. The gauge is intended for a quick practice evaluation, not as a precise manufacturing gauge.
The contact lens gauge has a wide groove in the front surface (the groove does not show up well in the photo). One side of the groove is on an angle. By inserting the contact lens the user can get a quick reading.
