What is the difference between wide view progressives and free form progressive?

[Nathalia Eyeglasses]

So, does anyone here know what is the difference between wide view progressives and free form progressive? I see there is an option for free form and wide view. Which should I chose and why?

[Karissa Eyeglasses]

The essential difference between free-form surfacing and conventional surfacing (CS) is that free-form equipment has the capability to produce greater precision (three axes or more) and smoother surfaces as well aspheric, atoric or progressive lens surfaces.

Lens surfaces processed on conventional equipment have to be fined on laps before polishing and it is the lap fining process that restricts the lens curves to circular surfaces—spherical or toric. For this course, HD will be used generically to mean precision cut, free-form surfaces.

I need progressive glasses, because i don't like glasses that has a line, so do i have to chose wide view progressive? do you think that package is perfect for my glasses?

There are different types of progressive packages, "Wide View" Progressive use a new technology called rear surface Varifocal design.
