查询词典 Lens

We placed the lens holder, testing lens, and the assistant lens in the testing optical path. When the testing lens was mounted in the lens holder, we took five dynamic interferograms. After rotating the testing lens by 180 degrees along the edge of the testing lens, we took another set of interferograms. Then, we could evaluate the centering error of the testing optical element by analysing these two sets of interferograms.

在待测光程中加入透镜治具、待测透镜与辅助透镜，当待测透镜贴靠於透镜治具，此时撷取五张连续相移干涉图，之后由待测透镜配合透镜治具沿待测透镜外缘旋转180度，再撷取另一组干涉图形，最后由两组干涉图进行分析，以测量光学元件的偏心误差值。

The difference of mean intraocular pressure among readings obtained with the lens in place, after lens removal and lens reinsertion were not statistically significant in bandage contact lens group and in low myopic contact lens group. But the high myopic contact lens group showed statistically significant difference of mean intraocular pressure obtained with the lens in place, after lens removal and lens reinsertion. In addition, the intraocular pressure readings measured immediately after myopic contact lens reinsertion revealed poor reliability.关键词 Tono-Pen , Soft contact lenses

我们把受测者分为三组：低度近视组，高度近视组和配戴治疗性隐形眼镜组，每组分别以受测者未戴隐形眼镜时的眼压做基准，而以其他三种情形的眼压分别与之比较，结果发现以Tono-Pen测量低度近视组和配戴治疗性隐形眼镜组的眼压值可信度较高，但是戴上隐形眼镜之后马上测量的眼压值较不准确，而高度近视组的测量值则出现变异的现象，可信度较低。
