    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.

    摘要: Disclosed are a hand-held vision detecting device and a method for using the hand-held vision detecting device to realize various eyesight measurements without wearing glasses and the steps therefor, wherein the hand-held vision detecting device at least comprises: an imaging lens group consisting of at least one imaging lens (16) and an eye chart (4). The cornea (15) of the subject can be located at the focal point at one side f the imaging lens group (16). The center of the eye chart (4) is provided at the other side of the imaging lens group (16) and can move forwards and backwards along the optical path. By using this device, the following functions can be achieved: 1. visual acuity measurement of the naked eye; 2. corrected visual acuity measurements; 3. measurements for detecting the strength of the glasses which should be worn when the corrected visual acuity is 1.0; 4. poor vision and amblyopia vision detection; and 5. astigmatism detection. People can detect vision anytime and anywhere through this device and detection method via simple and easy operations, and the detection results are accurate.
