Optometry apparatus capable of measuring para-central defocus
Disclosed is an optometry apparatus capable of measuring para-central defocus, comprising a diopter measurement module. The diopter measurement module comprises a first light source (1) emitting a first light beam. The optometry apparatus also comprises a scanning module for adjusting the position of a light spot formed on the retina by the first light beam. The scanning module comprises a first reflecting mirror (3) and a second reflecting mirror (5) rotatably positioned in sequence in the emergent optical path of the first light source (1). The rotation axis of the first reflecting mirror (3) and the rotation axis of the second reflecting mirror (5) form therebetween an angle greater than 0 degree and less than 180 degrees.
