According to the needs of the surface shape testing we selected the structures and parameters completed the whole machine structure design as well as related components and regulating mechanism . Then we accomplished a trial production of prototype and tested the sample lens .

根据检测方案，进行零部件的结构选型以及参数确定；完成了整机结构以及相关的部件和调节机构的设计；完成样机的 试制，并且进行了 样片 检测。

Transformation of Lens The trial results show the good correction for lens - distortion images .

试验显示它对变形图像能 给出很好的 校正。

Analysis on the Reports of Computer Optometry and Subjective Trial of Lens

电脑验光与主觉 试镜 验光结果分析

Keratometer was used to check the corneal curve at 2 direction for 3 times to offer the mean K value and a nearest basal lens to K value was selected as the trial lens .

步骤一：用角膜曲率仪测量角膜曲率，两个方向各测三次，取平均值，得到角膜曲率的平均K值，选取与K值接近的镜片作为 试 戴 片。

Please look let me remove the trial lens .

来，请向上看，让我帮你把 试 戴 片 摘下来。
