Note: Share measure is NOT based on purchases from the vendor or number of boxes sold, but rather on retail sales through the practice to its patients/customers.

Included:

  • Alcon and CooperVision soft contact lenses (retail sales)
  • Your total soft contact lens sales for that quarter


Excluded:

  • Specialty lenses, rigid gas permeable (RGP) lenses, and hybrid lens designs
