Distributors should prioritise reliable, repeatable left-eye capture with correct orientation, L/R flags, and metadata export so clinics can attach images to records and preserve longitudinal comparisons. Supplier-declared specs — exemplified by MAIKONG models MK 980U and MK-9822U — should describe optics, resolution, lighting behaviour, supplied software and accessories, and include training materials such as a one-page left-eye SOP, short video, and acceptance checklist. Canadian distributors must also verify local regulatory status and provide bilingual documentation where required before marketing an iridology camera.
