Varifocal glasses with a difference
Is there a perfect pair of varifocal glasses for every occasion: for your job? For your favourite hobby or sport?Varifocals are optical superstars: they offer near vision, distance vision and clear vision in the intermediate zone in just a single lens – and all without any perceptible transition. Many spectacle wearers aren't aware how precisely varifocal glasses can be customised to meet their particular needs. We've compiled a few special varifocal lens solutions for you which have almost become standard at ZEISS and at your ZEISS optician. Maybe you'll find your own personal vision solution amongst them. The good news: there's a solution for everything. Don't be shy: ask your optician.
A reader wrote to us at BETTER VISION to inquire if you can switch around the individual vision zones on a pair of varifocal glasses. This particular spectacle wearer does a lot of overhead work and thus requires optimal near vision through the upper section of the lens, along with good intermediate distance vision through the lower section of the lens.
Producing this sort of varifocal glasses is particularly challenging because the spectacle lens design is normally the exact opposite of what this wearer requires. Nevertheless, it is possible to change the vision zones on the lens! This is especially demanding work for the optician: all measurement data, the centration and the calculation of the cylinder axes sent to the Production Department at ZEISS must be exact. Using this information, special varifocals can be manufactured using freeform technology.
