High-volume refraction benefits most. Saving a label-read on every lens change adds up across a full clinic list, and the gain is in flow rather than in any single measurement.
Busy hospital clinics running to appointment times gain from faster selection, particularly where several clinicians share one set.
Shared sets are returned more accurately, since a lens in the wrong colour bank is visible without checking labels.
Teaching clinics can use the colour grouping to help students learn the structure of a lens set before they know it by heart.
Practices already using colour-keyed equipment elsewhere may prefer consistency across their kit.
Main refraction rooms suit a large set that stays in place, with the case for storage or occasional transfer.
Clinicians with red-green colour vision deficiency gain less from the keying, though bank position still distinguishes the groups.
Domiciliary work suits a compact set, since 6.0 kg is a two-handed lift.
