BS EN ISO 10943:2006

BS EN ISO 10943:2006 specifies minimum requirements and test methods for hand-held, spectacle-type, and head-worn indirect ophthalmoscopes for observing indirect images of the eye fundus.

BS EN ISO 10943 is not applicable to condensing lenses used for indirect ophthalmoscopy or to accessories. Nor does it apply to table-mounted instruments such as Gullstrand ophthalmoscopes and their derivatives, nor to ophthalmoscopes primarily intended for image capture and/or processing such as those based on scanning laser techniques.
