High-volume refraction benefits most, since a step saved on every lens change accumulates across a full list rather than showing in any single test.
Busy hospital clinics running to appointment times gain from faster selection, particularly where several clinicians share one set.
Shared sets are returned more accurately, because a lens in the wrong colour bank is visible without checking labels.
Teaching clinics can use the colour pairing to help students learn the structure of a set before they know it by heart.
Practices already using colour-keyed equipment may prefer consistency across their kit.
Main refraction rooms suit a tray that stays in place, since no case is shown for this version.
Clinicians with red-green colour vision deficiency gain less from the pairing, though bank position still distinguishes the groups.
Compatibility with existing frames depends on the unpublished ring outer diameter, which should be confirmed before purchase.
