Early Contact Lens (Aug, 1930)
Clumsy Specs Eliminated by Small Invisible Eye Glass
AWKWARD and all-too-conspicuous spectacles may in time go the way of ear trumpets and bustles when the diminutive and invisible eyeglasses shown in the photos above, an invention of Prof. Dr. L. Heine of Kiel, Germany, come into widespread use. The glass is a thin curved lens that is worn monocle fashion beneath the eyelid in the horny coat of the eye. It can be inserted or extracted by the patient.
