One version is aimed at diabetics.
Two patents secured recently by Google suggest the company is seriously pursuing the manufacture of contact lenses, according to Vanity Fair. The company is working on contacts with embedded cameras, as well as lenses aimed at diabetics who need to constantly monitor their blood sugar levels. In the latter application, an embedded “ophthalmic electrochemical sensor” would test the wearer’s tear fluid and alert him or her to any drops in blood sugar levels. The lens would include a working electrode and a much larger reference electrode. An antenna would also be included -— all on the convex and concave surfaces of the contact lens.
