The oxygen performance of a hydrogel contact lens is arguably its most important property when considering the possible physiological response of the eye. However, information about this aspect of a contact lens can frequently be difficult to obtain, and there are numerous pitfalls in the interpretation and application of the available data. This paper presents the oxygen permeability and oxygen transmissibility of 17 different lens types as measured by one technician in one laboratory across a short time interval. The clear relationship between water content and oxygen permeability is confirmed, and the transmissibilities of three lens types across a wide power range are reported.
在考虑眼睛可能的生理反应时，水凝胶隐形眼镜的氧气性能可以说是其最重要的特性。然而，关于隐形眼镜这方面的信息常常难以获取，并且在现有数据的解释和应用中存在许多陷阱。本文展示了由一名技术人员在一个实验室短时间内测量的17种不同镜片类型的透氧性和氧气透过率。证实了含水量与透氧性之间的明确关系，并报告了三种镜片类型在较宽屈光度范围内的透过率。
