Triple Magnifier for Jewelers
HERALDED as the first improvement in the familiar jeweler’s magnifying eyeglass in 50 years, this triple lens magnifier has been developed by a Hollywood inventor. The lenses are hinged on top, can be used independently or in combination. Result: choice of magnifying powers of two, five, and eight times respectively.
Entire outfit fits over ordinary spectacles.
