Equipment is established for measuring neural contrast sensitivity functions (NCSF) of human eyes. The contrast sensitivity function (CSF) of whole eye and modulation transfer function of optical system of the eye can be measured synchronously, and the NSCF can be calculated from CSF and modulation transfer function conveniently. Compared with achieving NSCF by measuring total-vision CSF and modulation transfer function respectively by two equipments, this method considers the dynamic character of human aberrations, and simplifies the measuring course. Compared with achieving NSCF by conventional laser interference, this method avoids the disadvantages of coherent noise and laser speckle, and can achieve NSCF of different luminance and different wavelengths by changing the luminance and color of visual target. NSCF of four normal eyes are measured with green visual target, and the results show that NSCF are variable in subjects, and the corresponding spatial frequency of NSCF peak value is higher than that of spatial CSF of whole eye.
