Using a micropolarographic system, the responses of seven human corneas to oxygen atmospheres ranging from 20.9% to 0% were measured. Under normal atmospheric conditions, ratios of oxygen demand were observed between corneas as great as 1.23:1. Following 0% oxygen conditions, however, these ratios rose to a maximum of 1.93:1, i.e., representing demand differences between particular corneas of nearly 2:1. Such differences may prove increasingly important in the gauging of patient suitability and safety in relation to hypoxic stress, e.g., the extended wear of contact lenses.
使用微极谱系统，测量了七个人类角膜对从20.9%到0%的氧气环境的反应。在正常大气条件下，观察到角膜之间的需氧比高达1.23:1。然而，在0%氧气条件下，这些比例上升到最大值1.93:1，即特定角膜之间的需求差异接近2:1。在衡量患者对缺氧应激（如隐形眼镜的长期佩戴）的适用性和安全性方面，这种差异可能会变得越来越重要。
