The anti-counterfeiting marks on Zeiss lenses may be worn away by processing. If you have astigmatism, it may be cut off by processing, or the processing master does not have the habit of leaving marks. It is possible that the anti-counterfeiting marks will be worn away. Many reasons can cause the anti-counterfeiting marks to be worn away.

Because the lens itself is a large round lens, the peripheral part of the lens must be ground off in order to be assembled into the frame, and the anti-counterfeiting marks are usually placed toward the edge. Zeiss is double anti-counterfeiting. If you want to know the authenticity, ask them to provide the original packaging of the lenses. Scan the anti-counterfeiting QR code and check the power to see if they match. If they are consistent, there is basically no problem.

The difference between Zeiss lenses and ordinary lenses:

1. Different meanings of lenses

Zeiss is a lens brand, and the lenses produced by Carl Zeiss are called Carl Zeiss lenses. Ordinary lenses are actually high-definition in a literal sense, and there is no such term in the professional field.

2. Different technologies

Carl Zeiss lenses have many patented technologies and are a global and international company that is a leader in the fields of optics and optoelectronics. The so-called ordinary lenses are only produced using general technology.

3. Different materials

Carl Zeiss lenses are basically made of BS-titanium, which has a longer service life than ordinary lens materials and is also resistant to sweat and corrosion. . Moreover, its fatigue strength and corrosion resistance are superior to traditional titanium alloys. The so-called ordinary lenses just use ordinary glass lenses or resin lenses.
