text: Col. John G. Tugwell, 186th Medical Group chief optometrist, determines the current prescription on a patient’s eye glasses during Cajun Care 2014 in Abbeville, La., March 2, 2014. Once he determined new prescriptions for his patients, they were able to have glasses made at no charge to them. Patients were encouraged to come back the next day to pick up their free eye glasses.
