摘要： A binocular refractometer is provided. The binocular refractometer includes a light source, a converging lens group, a light splitting apparatus, and an optical element adjusting apparatus. The light splitting apparatus splits measuring light into two beams of light, wherein a first beam of light of the two beams of light passes through a first fundus oculi imaging light path and forms, on a first imaging unit, a first dot pattern responsive to light reflected from the fundus oculi of a first human eye, and a second beam of light of the two beams of light passes through a second fundus oculi imaging light path and forms, on a second imaging unit, a second dot pattern responsive to light reflected from the fundus oculi of a second human eye. The optical element adjusting apparatus is configured to adjust the first and second fundus oculi imaging light paths along the direction of the pupillary distance. The optical element adjusting apparatus is configured to adjust the light source along the direction of the optical axis of the measuring light to fog the first human eye and the second human eye, so that for subjects with different diopters, the first dot pattern responsive to the fundus oculi of the first human eye is clearly formed on the first imaging unit and the second dot pattern responsive to the fundus oculi of the second human eye is clearly formed on the second imaging unit. The light source is conjugated to the fundus oculi of the first human eye predetermined by the converging lens group. The light source is conjugated to the fundus oculi of the second human eye predetermined by the converging lens group. The binocular refractometer can measure binocular diopters and the pupillary distance, and can accurately determine binocular astigmatism and binocular astigmatic axis angle.
