Introducing Vista PAL
Eye path of different Add
So, if he is using a conventional PAL, he may not have problems. But, for a wearer that has a high add, his eye actually converges more, and at the same time, it doesn’t drop as low as when his add power was lower. Presuming the wearer requires a +3.00 reading add and he is being prescribed with a conventional PAL, his eye may only reach say, +2.75d. So, because of this, that is why you find that you may have to increase the addition for some patients.

Eye Element Technology
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.
|The surface of the lens is scanned by a 3D measuring system, mapping the curvatures of the lens. The optical power is created by 3 parameters: thickness, index and curvatures||Light does not always travel straight into the eye|
Eye Element technology allows the progressive wearer to view clearly without moving their head….
……regardless of the path, light travels
The surface data & a highly advanced mathematical algorithm are the basis to Eye-Element Technology which takes into account numerous parameters:
- Lens index refraction
- Lens prescription
- Lens center thickness
- Distance from the eye to the back vertex of the lens
- Distance from the lens to the object
- Object’s angular position in the eye’s field of vision
- Pantoscopic tilt of the frame
- Pupil distance
- Thickness reduction prism, and more.
