Does the manufacturer of spherical lens analyze the difference between spherical and aspherical? (3)

The difficulty of making aspherical mirror for manufacturer of spherical lens lies in its geometric size design and precise control of geometric size. At present, the technology in this aspect is more advanced in Japan. At present, there are two main ways to process aspherical mirrors: one is to reprocess the spherical lens by high-precision grinding technology (manual or mechanical); One is to use manufacturer of spherical lens with high precision mold for pressing or injection directly to produce aspherical mirrors.

Aspheric glasses are designed by manufacturer of spherical lens glasses. Aspheric glasses are flat on one side and curved on the other. Aspherical glasses have little distortion and are real and natural. Now the aspheric lens has gradually replaced the traditional spherical lens, aspheric lens with its thin, light, clear vision without distortion and other advantages become the majority of teenagers. Optional. The introduction of aspheric glasses on the Internet is also a lot. But it's all very vague and confusing. First of all, the manufacturer of spherical lens should explain that the general appearance of the aspheric lens is that one side is flat and the other side is curved.

1, a part of the aspheric glasses people will wonder why their aspheric glasses than the original spherical glasses thickness is not much thinner? There is a misunderstanding about this in the comments on the Internet. Some netizens say that aspheric glasses are nearly twice as thin, but this is an exaggeration. Aspheric glasses are only 10 to 20 percent thinner than spherical glasses (except ultra-thin aspheric glasses).
