Apparatus to non-invasively measure glucose or other constituents in aqueous humor using infra-red spectroscopy

摘要

This invention relates to blood glucose measurement by hand held devices and by devices designed into vision glasses and that optically measure glucose concentration in the aqueous humor of the eye. The invention uses fiber optics and graded index (GRIN) lenses to precisely locate and direct an optical beam transversely through the cornea and aqueous humor to allow a precise measurement of the glucose concentration. Vision glasses in accordance with the invention contain components within their frames and allow continous blood glucose measurements.
