Antique 1920s Eveready Electric Examination Spectacles with Lamp & Battery Tube, Early Diagnostic Light

A remarkable pair of early electric examination spectacles fitted with a small nose-bridge lamp, wired to its original nickeled Eveready battery tube marked "Eveready Case No. 2692, 2 Unit Cells No. 950, Lamp No. 1198, Made in U.S.A." Hands-free illumination of this sort was marketed in the 1910s and 1920s to physicians and precision workers alike, putting a focused beam exactly where the wearer looked decades before the modern headlamp. The round ebonite-rimmed spectacles and twisted cloth cord survive together as a wonderfully strange piece of early electro-medical design. Ceramic display head not included.
