A non-powered, portable component of an intraocular pressure-reducing vacuum system designed for the noninvasive, bilateral reduction of intraocular pressure (IOP) by creating a reduced pressure environment around the eye for the treatment of open-angle glaucoma. It is in the form of a pair of goggles, worn by the patient during treatment sessions in a clinical setting, with tubing attached to the lenses intended to be connected to a pump (not included) to monitor pressure and regulate suction applied to the microenvironment in front of the eye. This is a reusable device.
