Frenzel goggles are a diagnostic tool used in ophthalmology, otolaryngology and audiovestibular medicine for the medical evaluation of involuntary eye movement (nystagmus). They are named after Frenzel, a German physician.
Usage:
The purpose of the goggles is to disable the patient’s ability to visually fixate on an object while at the same time allowing the examiner to adequately visualize the eye. This is done by using high-powered (+20 diopters) magnifying glasses with an illumination system. With such a high-powered lens, it is unlikely that the patient can adequately focus and visually fixate on an object to suppress nystagmus.
Warranty period – 3 years.
D
ifference between the
offered
Frenzel goggles and common Frenzel goggles on the market:
– the way the patient’s eyes are illuminated. T
raditional Frenzel goggles uses two bulbs or LEDs. Our
Frenzel’s goggles provides uniform illumination of the patient’s eyes.
– our goggles have 50 mm
lenses
, common goggles – 30-40 mm.
This is a significant factor which facilitates the recognition of low-amplitude nystagmus.
– the battery compartment of
the goggles offered is located directly on the mask. Most of Frenzel goggles on the market have
battery compartment
in form of a separate unit, which makes
positional maneuvers
inconvenient, when both doctor’s hands are occupied, and the long wire could get entangled.
–
the mask of the Frenzel goggles offered is soft, has an ergonomic shape, it fits well to patient’s face.
–
the weight of
of the Frenzel goggles offered
is only 220g, the weight of the most Frenzel goggles on the market is 400-600g.
