Hold up your clean spectacles at an angle to the light. The light reflection then causes the subtle ZEISS laser mark to appear at the outer rim of the lens. The laser is operated with a wavelength that only permits a low level of penetration. After all, people looking at the wearer should be able to see the ZEISS quality seal, but the wearer's vision should not be impaired by it at all.
Our eyes are our most important sensory organ. And since each eye is as unique as a fingerprint, it requires a customised visual analysis at your optometrist.
