A Clearer Vision
Michael Hoskins, 2nd Aerospace Medicine Squadron paraoptometric technician, positions a patient's eye for a glaucoma test on Barksdale Air Force Base, La., March 26, 2014. To test for glaucoma, optometry technicians use a tonometer, which shoots a puff of air into the patient's eyes. The air is used to measure a patient's eye pressure. Glaucoma is the leading cause of blindness in America, which is why it is essential to catch it early. (U.S. Air Force photo/Senior Airman Benjamin Gonsier)
