Gradal Individual® FrameFit®
Zeiss are one of the world's leaders in lens design, and are particularly known for advances in varifocal lenses. Their new varifocal lens, Gradal Individual® FrameFit® launched a few years ago, is entirely bespoke to fit your unique prescription and frame choice, making these lenses easy to get used to, with significant improvements over other designs of varifocals.
·   You will enjoy a smooth and more gentle transition from near to far vision or vice versa, giving you comfortable and clear vision at all distances
·   Your distance vision will be clear and distortion free over the whole width of your lens, so more comfortable when you're out and about
·   You will enjoy a wide field of near vision, so you don't have to turn your head for example while reading your broad sheet newspaper
·   You will also appreciate a wider area of clear vision at mid-distance for example using a large computer screen
·   This varifocal works with almost any frame size, so you can select the frame of your choice
·   Most importantly you will find you'll be comfortable wearing just one pair of spectacles for driving, sight-seeing, walking round, reading your newspaper and looking at your computer
How it Works
Advances in computer technology, together with the skills of Zeiss' technicians, have made it possible to manufacture totally bespoke lenses for you.
Once you have chosen your frames, a number of measurements will be taken, taking into account not just where your pupils sit in relation to your frames (as with other varifocals), but also the exact shape and dimensions of your chosen frame and how the frame sits on your face, for example what degree of forward tilt there is.
The lenses will also be tailored to your personal viewing behaviour - how you use your eyes and where your arms feel comfortable holding your reading documents.
All this information is then fed into Zeiss' computer software, enabling individual lenses to be manufactured for you.
