Instead of producing progressive lenses with external progression and grinding the spherical and cylindrical powers onto the back of the lens-as was done in the past – the whole prescription of the patient can be applied on the lens back surface and individually calculated – thanks to freeform technology.
You will notice a slight divergence between measured and ordered values with Maxima Premium PAL lens , due to the fact that we automatically adapt the lens power based on the angle of inclination, BVD and the object distances relevant for different viewing fields.
The parameters applied for manufacturing a Nova 3Di are as individualised as your customers. They consist of:
1. Frame type-lens width (A height)
2. Lens height (B height)
3. Bridge width (DBL)
1. Pupilary distance
2. Back vertax distance
3. Angle of inclination
4. Horizontal inclination
5. Fitting height
Your customer is free to choose any frame. Based on the centering data we automatically determine the suitable progressive corridor length and produce it ultra- precisely. Anything is possible between a fitting height of 14 and 22mm (on lens geometric center lacking precision). You do not need to worry any more about progressive corridor lengths. With Nova 3Di, we adapt the progressive corridor length precisely to the desired fitting height.
This results in perfect binocular vision and an outstanding 3D perceptio
