The invention discloses a computer
optometry unit. The computer
optometry unit comprises a
fogging light path and a focusing light path, and is characterized in that the focusing light path comprises a
laser, a
first light source lens, a second
light source lens, a PBS, a first spectroscope, a second spectroscope, an objective lens, a first focusing lens, a second focusing lens, a telecentric diaphragm, a
cornea objective lens and a first
detector. The second spectroscope, the PBS, the
first light source lens, the second
light source lens and the
laser are located on a first
optical axis and are sequentially arranged on the same
optical axis, the first spectroscope, the objective lens and the second spectroscope are located on a second
optical axis and are sequentially arranged on the same optical axis, and the first spectroscope, the telecentric diaphragm, the
cornea objective lens and the first
detector are located on a third optical axis and are sequentially arranged on the same optical axis. The first focusing lens and the second focusing lens are symmetrically arranged along the third optical axis and are located between the first spectroscope and the telecentric diaphragm. The unit has the advantages that whether the vertex of the
cornea is focused or not is judged simply, visually and accurately, the focusing accuracy of the vertex of the cornea is improved, and high-precision and high-
repeatability measurement of human eyes is realized.
