  • Abstract
  • Look Inside

We developed, four years ago, a portable refractometer (GR-M3) intended for infants and handicapped persons. It could be used with both eyes of the examinee open. We now produced an improved version (FR5000) which is smaller in size and allows rapid measurement. It weighs 5.4 kg and easy to be carried. One measurement requires 0.49 second and consecutive 9 measurements are completed in less than 5 seconds. These features promise to facilitate refractometry in persons with unstable body position or irregular eye movements.
