What does lens optics mean? _Industry information_

Lens optics, also known as optical lenses, are mainly used in the eyewear industry. The purpose is to correct the refractive error of the patient's eyes, thereby increasing the clarity of vision. or optical lenses. So let's take a look at other information about lens optics and some features of lens optics. The reason why optical lenses can correct the diopter of the human eye mainly follows two principles: one is that the lens used is combined with the diopter of the human eye to form an overall diopter combination, which can just make distant objects fall in front of the retina. It forms a clear influence, so that people who wear the lens optics can clearly see the shape and influence of the object. The other depends on the refraction of the human eye. If it is farsighted, the light beam must be collected first and then converged by the human eye; myopia must first diverge and then converged by the human eye. The optics in the lens, in simple terms, is to use the principle of the perspective lens, so that the human eye with refractive error can be clearly presented in front of the patient's retina through the lens, so as to correct the refraction and give the wearer a clear vision. Effect. However, there are two main materials currently used for lens optics: one is glass lens, the main component is silicon dioxide, and the light transmittance and refractive index are relatively high; the other is natural material, such as resin lens, which is stronger than glass lens The light transmittance and refractive index of the lens are higher, but the hardness is softer. To sum up, the lens optics is to use the principle of the perspective lens, so that the human eye can see the clear effect when viewing objects. That is to say, a lens is installed in front of the eyes of patients suffering from refractive errors, so that the patients can see things clearly and comfortably.
