Carl Zeiss AG is a German company that manufactures optical systems, industrial measuring instruments, and medical equipment. The name of the company comes from one of its founders, German optician Carl Zeiss (1816-1888). It was established in Jena in 1846 by Carl Zeiss, Ernst Abbe and Otto Schott.
Zeiss resin lens guarantees up to 99.4% of the lens light transmittance. The naked eye can no longer feel whether the lens is worn or not. So far, only Zeiss, the leading optical industry, can bring such extraordinary extreme effects. Moreover, in order to ensure the good imaging quality of the lens and make the lens longer life, Zeiss also adopted a new coating design, imported from Korea. The unique professional technology is combined with nanotechnology so that they manufacture the good quality of the top lens.

Design principle of progressive multifocal lens
For the same piece of the lens, the top is used to see far, the bottom is used to see close. The upper and lower degrees are different.
There is not a sudden change in the distance degree fixed above the lens to the near degree fixed below the lens, but a gradual transition between the two through gradual changes in refractive power, which has special benefits over common bifocals or trifocal lenses.
Can night driving glasses prevent blue light?
Night driving glasses are called night vision goggles. Some night-driving glasses have anti-reflective coatings. Night driving glasses reduce glare by scattering and filtering blue light. Blue light is the shortest wavelength in the spectrum and is possible to cause glare when it enters the eye. The night driving glasses, available in colors from yellow to amber, filter out a lot of glare, and other light, and then make it difficult to see in dark conditions. But tests and studies have shown that night driving glasses don't improve night vision or help drivers see pedestrians faster than they won’t wear them.

A progressive piece is suitable for most old people to wear. The proper person is the one who has the visual needs of the long, medium and short distance cares about beauty, and is willing to accept new things. In order to avoid binocular vertical prism differences, for the wearer whose equivalent spherical lens with anisometropia is more than 2D, especially if the difference in refractive power of the vertical meridian is more than 2D, it should be checked with caution. Opticians whose vision needs do not match the progressive lens design, like dentists, often experience blurred vision when working with the far side of the lens to look closer.
