PERFECT BALANCE. VISION WITHOUT DISTORTIONS.

SO PRECISE TO BECOME INVISIBLE.

FOCALIS is the latest-generation progressive lens developed by DAI Optical to offer clear, stable, and comfortable vision at all distances, with faster and more natural adaptation. Its advanced optical design is engineered to minimize peripheral aberrations, particularly lateral astigmatism, which is responsible for much of the visual discomfort experienced by wearers of traditional progressive lenses.

At the heart of FOCALIS lies ADVANCED GRADIENT CONTROL technology, an advanced power-gradient management system that harmoniously distributes the progression curves, minimizing oblique astigmatism and enhancing visual quality even in the lateral areas of the visual field.
FOCALIS is the ideal solution for anyone seeking top visual performance in a progressive lens: technology, comfort and adaptation come together in a single, evolved visual experience.

Advanced Gradient Control is an advanced power-gradient management system within progressive lenses, designed to optimize the distribution of progressive surfaces across the entire lens area. Through refined mathematical control of power variations, this technology enables a smoother transition between the different vision zones (distance, intermediate and near), ensuring a natural and comfortable shift of the gaze.

The action of Advanced Gradient Control focuses particularly on reducing induced oblique astigmatism, one of the main causes of distortion and visual discomfort in the lateral areas of the lens. By minimizing these unwanted aberrations, the technology significantly enhances peripheral visual quality, expanding the usable viewing area and delivering a more stable, sharper experience in every direction of gaze.

FOCALIS is the ideal solution for anyone seeking the highest level of visual performance in a progressive lens: technology, comfort and adaptation merge into a single, evolved visual experience.

Smoother transitions between vision zones: reduces abrupt power changes, preventing distortions and visual fatigue.

Reduction of induced oblique astigmatism: minimizes lateral aberrations, improving sharpness and peripheral image quality.

Greater stability and comfort: thanks to an optimized power distribution across the entire lens surface, the visual experience feels more natural in every direction of gaze.

Wide usable vision area: maximizes the lens surface, making everyday vision more comfortable.
