Note. The examination of the refractive state of the eye is called an optometry. 3.1.3 Adjustment Visual adjustment The phenomenon that the refractive power of the eyes changes when changing the distance and near objects. 3.1.4 Aberration In actual optical systems, the results obtained by non-paraxial ray tracing are not consistent with the results obtained by paraxial ray tracing, which is inconsistent with Gaussian optics. (First-order approximation theory or paraxial rays). ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 38120-2019_English be delivered?Answer: Upon your order, we will start to translate GB/T 38120-2019_English as soon as possible, and keep you informed of the progress.
