On this trip, I was part of a 9 person Optometry Team, so I was able to obtain a tremendous amount of hands-on experience with working with patients. Prior to the trip, we were taught basic techniques and methods used in standart eye examinations. We tested patients for near and far distance vision using a Snellan eye chart, and we measured astigmatism and prescription prediction using an auto-refractor.
I learned so much about optometry from the first-hand experience I received from this mission. Looking back on it, I enjoyed every aspect of the eye examination process, even the 12 hour workdays we had.
