If you expect a minimum of four turns per year from your frame board inventory, why would you tolerate a contact lens inventory with no turn data? Annette Juneau�s Juneau Practice Management Institute (JPMI) provides a benchmark for its clients. The formula is: total value of the owned inventory divided into the annual contact lens cost of goods.

Although this is the average turn rate for JPMI clients, the data is study-validated. Don�t expect anything less of your contact lens inventory than you do of your frame inventory � four turns a year.
