OPUS CURVE TECHNOLOGY incorporates a trigonometric algorithm to achieve - what we believe to be - the most finitely calculated VARIABLE FRONT CURVATURE of ANY multi-focal lens. At any given point in the progression, the base curve reflects the optimal value in relation to lens power (i.e. true POWER/CURVE synchronisation), thus ensuring "ideal optics".
BACKGROUD AND THEORY
AT THE SIMPLEST LEVEL, WE KNOW THAT TO ACHIEVE ‘IDEAL OPTICS’ (OPTIMUM ACUITY, MINIMISED PERIPHERAL DISTORTION) ANY GIVEN PRESCRIPTION MUST BE PAIRED WITH ITS IDEAL BASE CURVE*.
Despite its plethora of advantages over traditional surfacing techniques, freeform production of multi-focals has created a challenge in this regard due to its use of single-vision "blanks" with a fixed front curvature not naturally suited to a variable progression.
Whilst Optik Mizen’s CURVE COMPENSATION technology is extremely effective in mitigating for this fixed front curvature, some degree of compromise is inevitable, particularly with plus prescriptions and higher reading additions.
Our R&D team embraced the inherent challenge of 'first-generation' freeform surfacing several years ago, and set about creating a programme that would add a new dimension to our highly intuitive OPUS lens design software. This new programme is now complete and incorporates a unique trigonometric algorithm that is able to deliver what we believe to be the most accurate, most optically ‘ideal’ variable front curvature of any multi-focal lens in production. Available on several flagship designs across the NATURAL LIFESTYLE SERIES of our SPACE & TIME portfolio, this new technology delivers enhanced acuity to all patients courtesy of its TRUE power/curve synchronisation.
The precise nature of the variable front curvature of OPUS CURVE TECHNOLOGY affords exceptionally sharp focus throughout the entire lens progression.
