Patented the 1st progressive lens

filed the patent for the first progressive lens (patent granted 1923); her work with Edgar Tillyer at the American Optical Company (now part of Carl Zeiss Vision) improved the optics of eyeglasses, cameras, telescopes, and military optical instruments; worked as a geometric optician with Tillyer for nearly 10 years, doing the mathematical work to develop the Tillyer corrected curve lens but didn't receive credit for her work; developed a breakthrough camera lens; 1946 she published a paper on "Practical Methods of Computing Finite Throw Schmidt Systems;" did considerable mathematical research on the theory of iseikonic systems especially focused on investigating the theory of variable magnification systems without change in focal power and applied this theory to variable size lenses;

Wide aperture lens system having means for reducing spherical aberrations; Size testing system; Opthalmic lens; Optical system for measuring changes in magnification; Lens testing instrument; Lens seating device; Lens; Lens-grinding machine; Wide aperture objective; Image projection optical system; Measuring device
