Thanks to two new technologies the varifocal lens compromise between fields of vision and swim effect has been overcome, and patients can now experience ultimate vision.

Fields of vision dictate how much head movement is required for a patient to read comfortably in intermediate fields, and the "Swim affect" often affects middle distance and reading and can be very disconcerning, it is for these reasons that many patients reject a lens. This can often be minimalised using better quality lenses but is often still an issue.

 With the Varilx S Series lens patients benefit from up to a 50% wider field of vision and from up to 90% less swim effect than the market leaders.
