Conclusion : When the incident pupil 2h of focimeter is corresponding with human pupil the measuring value of the back vertex power is the real back vertex power of contact lens the reciprocal of distance on the orientation of image L0.87h ′ of band height 0.87h light .

结论：焦度仪的入瞳2h与人眼瞳孔相匹配时，测量的接触 镜后 顶焦度就是接触 镜实际后顶焦距&带高0.87h光线的像方截距 L0.87h′的倒数。

Optical coherence tomography for ophthalmic imaging Results : The spectacle magnification is relative to the power of the correcting lens and distance of eye from the back vertex of the lens .

结果：镜片 角放大率与矫正 镜片 屈光力，以及镜眼距有关。
