Hard and soft designs how to know

[Ladyoptician]

I am trying to make myself a reference chart on hard and soft design progressives. Does anyone know where I could find out which are which?

Very informative, thanks! Some were listed without any reference to design, but there were a lot on there!

Wouldn't it be nice if progressive companies told us these things? ::sigh...if only::

Ha! They only tell us what they think will get us to sell their lenses!!

We let people know all about our designs.:D

Really. No need to overcomplicate things by exagerating the difference in progresives. :cheers:

How do you know what other progressive to try if you have a failure and your not familiar with designs? How do you explain why sometimes a first time progressive failure will have success with another brand?

Progressive failures are due mostly to fitting errors and second to poor manufacturing. It has nothing to do with the lens brand.

Interesting. When you say poor manufacturing, do you just mean the optics themselves? Because I check optics before I dispense and if it is questionable, I have it remade. As far as fitting goes, Do you mean pd's being off? Seg height too high, too low? Because I make sure that is on target before they go out the door. Only reason I am questioning is because I have had patients fail in one brand, and not changed a seg height or pd and had them do wonderful in another brand. Input??

Really? So lets say a person was placed in an AO Compact but has always worn VIP and can't adapt. To me this is a design selection issue and has nothing to do with fitting or manufacturing. I think we are talking design not branding.

Yes. But mostly hard to detect surface defects. These are rare (how many rejects do you get). That is the reason when you change lenses types the problem gets fixed. The defect is not on the second pair.
