In order to measure various low-level aberration and irregular higher-order aberration of the human eyes accurately,the wave-front aberration measurement method with subjective visual compensation was proposed,which could ensure more accurate and realistic measuring results.The result shows the wave-front aberration obtained from subjective visual compensation measuring method smaller than objective measurement,which is the result of adaptive correction.In addition, when watching different sighting targets,the fluctuation value of wave front aberration is small.Therefore,a conclusion can be drawn that the 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.The conclusion is positive and beneficial to the aberration treatment of human eyes.
