The Ophthalmetron, operated by otherwise unskilled technicians, provides a good measure of the refractive error. It is possible to make reliable measurements even of young children without cycloplegia. Criteria have been developed so that technicians' results from the Ophthalmetron taken in conjunction with visual acuity can provide eyeglass prescriptions that accurately match the prescriptions of practitioners. The population studied showed a striking prevalence of myopia among Puerto Rican children, especially the girls.
