Vista Progressive Lenses has precise hi-tech Eye Element Technology that ensures accurate analysis necessary for Sophisticated lenses. By observing exact vision requirements, designers can finally create tailor-made lenses.

Eye Element Technology

The technology that enables us to design progressive lenses through an exact simulation

• f the natural human eye view.

Eye Element Technology

The optical power is created by 3 parameters: thickness, index and curvatures

The surface of the lens is scanned by a 3D measuring system, mapping the curvatures of the lens.

Eye Element technology allows the progressive wearer to view clearly without moving their head…. …… regardless of the path, light travels

Eye Element Technology

The surface data & a highly advanced mathematical algorithm are the basis to Eye-Element Technology which takes into account numerous parameters: 1. Lens index refraction 2. Lens prescription 3. Lens center thickness 4. Distance from the eye to the back vertex of the lens 5. Distance from the lens to the object 6. Object's angular position in the eye's field of vision 7. Pantoscopic tilt of the frame 8. Pupil distance 9. Thickness reduction prism, and more. By taking all of these parameters into consideration, Eye-Element Technology enabled the creation of the perfect progressive lens.

Clear Distance, Intermediate & Near Vision Zones

Eye Element Technology

Extensive research lead to major discovery …

A perfect harmony for the eyes. Eye Element technology that allows clear vision for short, mid and long distance with the same lens.

Eye Element Technology

Because Vista Progressive is based on the advanced Eye-Element Technology, vision clarity is enhanced even more, bringing it to an optimal level in every vision zone.

A technological breakthrough, Eye-Element Technology ensures the softest lens design for every vision zone, by pushing the distortions down and to the sides. Soft Design

Aspheric in all its zones, Vista Progressive is the thinnest possible lens. Vista Progressive is designed for a variety of frame sizes - small and large alike.

Asphericity and Easy Adaptation

Eye Element technology offers the softest feel among any progressive lens. It adapts to you rather than making you adapt to it. Ultra Soft Design
