We investigated optometric aspects of advanced health service system of the American Forces, considering necessity of sirnilar system for the Korean Armed Forces. The U. S. military optometric service system was investigated on the basis of open materials given by the American Army, Navy and Air Force, focusing on military optometrist and optical laboratory specialist positions. We compared the results of investigation with present status of optometric servicets of the Korean Armed Forces. The American Forces have an advanced optometric service system managed by the military optometrists. who are similar with the military medical officers. and optical laboratory specialists, who are considered as expert groups. The U. S. military offers soldiers eye test and optometric services of very high quality, while the optometric service of the Korean Armed Forces is very limited and much improvement is required for better eye health and visual care. We think that it is necessary to introduce an optometric specialist position to the Korean military organization for better cornbat capability.
