  • Abstract
  • Look Inside

A Topcon-III Refractometer was modified for measuring the refraction of the eye by utilizing the infrared rays. The refractions of the spe-cially devised schematic eyes and of the human eyes were done with both the new infrared refractometer and the ordinary Topcon-III using white light. The subjective refractions of the human eyes were also determined. The cali-bration of the data were discussed from the results that the infrared refraction was shifted to plus (hyperopic) side compared with the white light refraction, but the shifting was slighter in case of the human eye than the schematic eye.
