Remote Measurements of Tear Electrolyte Concentrations on Both Sides of an Inserted Contact Lens
Chemosensors, 2023 In this paper, a method is described to perform ion concentration measurements on both sides of an inserted contact lens, without physical contact with the eye or the contact lens. The outer surface of an eye is covered with a tear film that has multiple
