At IKYUM®, true innovation isn’t measured by marketing claims, but by the ability to unite optical performance, scientific rigor, and perceptual comfort. Too often, marketing simplifies reality — it’s always easier to sell a dream than to explain an optical trade-off.

Technology doesn’t erase optical physics — it refines it.
For years, progressive lenses were built on standard geometric models. The shift came with FreeForm digital surfacing, enabling point-by-point computation across the entire lens surface. With advanced algorithms, each viewing zone is optimised to deliver a more precise, stable, and fluid experience — where every power variation is controlled and tuned rather than endured.

Understanding what the brain perceives
Behind every gaze lies a unique way of perceiving, moving, reading, living. Adapting to progressive lenses is therefore not just about diopters; it is a genuinely neuro-sensory experience.

Individualised “Hard Design” geometries (Horizon One+) deliver outstanding central sharpness and instant responsiveness — ideal for experienced wearers or precision tasks. Their marked progression calls for a brief neuro-visual adaptation, with a narrower intermediate zone, yet they remain comfortable for near work (tablet, phone, documents) and provide excellent distance and near vision.

The most advanced individualised “Soft Design” geometries (Horizon 360+ Select and Dual Fusion+) feature a smooth, even progression, enabling fluid transitions and more harmonious sensory integration. This makes them the natural choice for mixed use — mobility, office work, multitasking — where the gaze shifts across distances without perceptible effort.

IKYUM® Energy Flow: balance, mastered

Our approach combines optical precision with perceptual comfort to create a coherent visual flow, guiding the eye from far to near without breaks or strain — so technology supports the gaze rather than constraining it.

The optician’s expertise: the key to performance
A design only reaches its full potential through precise fitting. Through accurate measurements and know-how, the optician brings the technology to life and reveals its true visual fidelity.
