具有主观视觉补偿的人眼像差测量方法

为了准确测量人眼的各种低阶像差以及不规则的高阶像差,采用具有主观视觉补偿的人眼波前像差测量方法,进行了理论分析及实验验证,在客观测量的同时进行了主观视觉补偿,得出了测量的准确数据。结果表明,主观视觉补偿测量的波前像差小于客观测量的结果,被测者在观察视标时的适应性调整减小了波前像差,并且对于观察不同的视标时,波前像差的波动值较小。采用主观视觉补偿的测量方法,考虑实际观察目标时眼睛的状态,能够很好地对人眼像差进行补偿,得到符合实际状态的眼像差,这对制定人眼像差的治疗方案是非常有帮助的。

Ocular aberrations measurement method combined with subjective visual compensation

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.
