Objective: The human eye is an imperfect refractive system which not only has defocus and astigmatism, but also spherical aberration, coma and anomalistic high-order aberrations, all of which have influence on the imaging quality of retina. Further research revealed that human eye visual imaging is not only connected with refractive system, but also is closely related to the subjective judgment of human brain and the process of neural system. Method: Wave-front aberration measurement method and its measuring system which have subjective visual compensation are proposed and conducted in combination with objective measurement, which ensure more accurate and realistic measuring results. Result: Wave-front aberration obtained from subjective visual compensation measuring method turned out to be smaller than objective measurement, which is the result of subjects’ adaptive correction when watching sighting targets. In addition, when subjects are watching different sighting targets, the fluctuation value of wave front aberration is small. Conclusion: Subjective visual compensation measuring method takes into consideration the actual condition of human eyes when watching targets which contributes to aberration measuring improvement and obtains results that match realistic state, all of which are of positive and beneficial value to the determination of human eye aberration treatment.
