Navy Hospital Corpsman 3rd Class Justin Kohn, NOSTRA optician, marks the axis — where the pupil is and the power of the prescription should be — on uncut glasses lenses during Innovative Readiness Training Ola de Esperanza Sanadora Sept. 2, 2018, in Guaynabo, Puerto Rico. The purpose of the IRT is to provide medical, dental and optometry care to assist local municipal authorities in addressing underserved community health and civic needs while performing joint military humanitarian operations.
