A new contact-lens prototype senses changes in pressure, which may one day provide continuous monitoring for patients with glaucoma. Each lens (pictured) consists of a transparent polymer with tiny, opaque electrical circuits (gold).
A tiny electrical circuit built into contact lenses may provide 24-hour monitoring for glaucoma. Currently, the only way for patients with glaucoma to keep tabs on the disease is to go to the doctor’s office. There, a clinician administers one of several tests to measure glaucoma’s main risk factor, intraocular pressure (IOP), and prescribes medication accordingly. But such visits normally occur two or three times a year, and there’s no take-home monitoring device for patients who may experience pressure spikes between visits.
