OPUS CURVE Technology

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 programme embraced this inherent challenge of freeform surfacing and set about creating a programme that would add a new dimension to our highly intuitive OPUS lens design software. OPUS CURVE 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. It is an integral part of the LIFE SYNCHRONICITY design and can also be applied to SOPHOS ELITE and AUTOBAHN HD.

The precise nature of the variable front curvature of OPUS CURVE TECHNOLOGY affords exceptionally sharp focus throughout the entire lens progression.
