The phoropter trapeze. A portable refractive support for remote clinics.
A trapeze was engineered using inexpensive pre-threaded commercial polyvinyl chloride ("PVC") plumbing pipe. This was suspended from a convenient overhead point and the phoropter was clamped to it. It was stabilized by the patient holding on two attached handles. Illustrated in photographs.
