Practices needing equipment secured benefit most. A closed case can be locked in a cupboard at the end of a clinic, which an open tray cannot, and that matters where rooms are shared or cleaned by others.
Infection-conscious clinics gain from lenses stored behind a lid rather than exposed on a bench between sessions.
Multi-site groups can move a cased set between clinics without handling loose lenses, which reduces the risk of a dropped or misplaced lens in transit.
Hospital eye departments suit metal rims, where a set is handled by many clinicians over many years.
Teaching clinics benefit from both the durability and the case, since sets used by students see the heaviest handling of all.
Practices with limited secure storage can keep the set in its case rather than dedicating a locked drawer to it.
Rooms where the set stays permanently on the bench may not need a case, and the plastic SL-266 costs less.
Compatibility with existing frames depends on the unpublished ring outer diameter, which should be confirmed before purchase.
