摘要

调制传递函数（MTF）是研究眼睛光学性能的最完整的工具之一。我们提出了68名受试者的平均径向MTF分布，这些受试者分为六个年龄段（从20岁到80岁），并提出了一个通用公式来估计人类MTF的径向分布作为瞳孔大小和年龄的函数。将每个年龄组的平均MTF拟合到分析表达式中，以计算与衰老相关的两个参数。所提出的公式与以往工作中的实验数据相当吻合，并预测了从MTF获得的不同光学质量参数随老化的平均变化。

Modulation transfer function formula for different age ranges.

The modulation transfer function (MTF) is one of the most complete tools to study the optical performance of the eye. We present the average radial MTF profiles measured in 68 subjects grouped in six age ranges (from 20 to 80 years) and a general formula to estimate the radial profile of human MTF as a function of pupil size and age. The mean MTF for each age group was fitted to an analytical expression to compute two parameters related to aging. The proposed formula fitted reasonably well to experimental data available in previous works and predicted the average changes with aging of different optical quality parameters obtained from MTF.
