Frenzel Lenses are used to magnify and illuminate the eyes while defocusing vision and minimizing visual fixation during the physical examination of eye movements
Frenzel lenses are constructed of light plastic materials resulting in a comfortable, easy-to-use system
The Frenzels stay in place well during Hallpike and head-shake tests
Lenses offer a large viewing area that allows the examiner to see both eyes without partitions or nose pieces in the way
Powered by standard AA battery pack or rechargeable battery pack
