A note about
hinged lense goggles
Hinged goggle allow the comparision of two conditions for detecting
nystagmus during provocationmaneuvers such as Hall-Pike Dix – one in
which fixation is unimpairied (room illuminated and lenses up) with
immediate switch over to a situation where fixation is eliminated (room
illumination is decreased and lenses are flipped down). Rapid
comparison of the two conditions is often helpful in confirming whether
eye movements are truly nystagmoid. Flip-up lenses also
allow cleaning of the lenses if they become fogged without removing
tham from the patient.
Lightweight. Frenzel Lenses made of light plastic materials including
the lenses, resulting in a comfortable, easy-to-use system. The
Frenzels stay in place well during Hallpike and Headshake tests.
Large viewing area. The large lenses offer a viewing area sufficiently
large to provide clear views of the eyes. The arrangement allows the
examiner to see both eyes without partitions or nose pieces in the way.
Safe. - Frenzel Lenses are powered by low voltage batteries,
eliminating the possibility of electrical shock.
Battery pack included.
