    • Eye refraction is measured to achieve desired quality via a selected vision characteristics. A characteristic of vision is selected to correlate to the desired quality of vision from a group of vision characteristics comprising acuity, Strehl ratio, contrast sensitivity, night vision, day vision, and depth of focus, dynamic refraction over a period of time during focus accommodation, and dynamic refraction over a period of time during pupil constriction and dilation. Wavefront aberration measurements are used to objectively measure the state of the eye refraction that defines the desired vision characteristic. The measured state of refraction is expressed with a mathematical function enabling correction of the pre-selected vision characteristic to achieve the desired quality of vision. The mathematical expression function may be a Zernike polynomial having both second order and higher order terms or a function determined by spline mathematical calculations. Pre-selected vision characteristics may be determined using ray tracing technology.
    • 通过选择的视觉特性测量眼睛折射以达到期望的质量。 视觉特征被选择为与来自一组视力特征(包括敏锐度,Strehl比,对比敏感度,夜视,日视力和焦点深度)的视觉特性相关联,在聚焦住宿期间的一段时间内的动态折射 ,以及在瞳孔缩窄和扩张期间的一段时间内的动态折射。 波前像差测量用于客观测量定义所需视觉特性的眼睛折射状态。 测量的折射率用能够校正预先选择的视觉特性以实现期望的视觉质量的数学功能来表示。 数学表达式函数可以是具有二阶和高阶项的Zernike多项式或由样条数学计算确定的函数。 可以使用光线跟踪技术来确定预先选择的视觉特征。
