I know we all have our favorite lenses to fit, but the question is, if you were in the drivers seat as far as designing your ultimate favorite progressive what would it be? Why would it be that way? What would you call it? Lets have some fun with this one!!
This would be done for marketing/sales reasons. I don't know what I will call it, yet.
I want something with all the bells and whistles and more. It will be as good as the Autograph II or similar premiums, but at a Generic price. It may only be available in limited materials and range in Prog, SV, Wrap and Office styles, but.....
Well those goals arent that far out of reach....Are you sure you haven't read the IOT Catalog?? ::end of pitch::
I've seen it, but I need one that is FULLY customiseable. Would need to compensate for panto, dihedral, vertex, frame size and shape, everything. I didn't see anything on the website or on the info that CC Systems sent me.
What I'm tring to say is, I want something that is better than anything currently on the market.
I think almost all of what's wanted in a Free Form progressive is already out there (except the slab-offs). We already have POW compensations, frame compensations, and wrap compensations, as well as decentration within the single vision blank. Now we just need it less expensive.....
I suppose the ulitmate lens would be a completely distortion free progressive.... or at least one where all of the distortion was cut out during edging even going into a 60 eye frame....
And I would name my lens the Parabola! Because the back surface no longer is.
Also, I want a Free Form in Glass. I don't care that the glass market supposedly is dying, we do 200+ glass jobs a day, and I've had two accounts ask me about it this week. I'm guessing that it's much more of a hardware issue than a software issue.
I would say it is impossible. Darryl Meister is the one that would know for sure.Quote:

Spherical front (able to specify front curve 2 diotpers up or down from optimal curve) with a variable corridor back surface design, latest generation. Must have the ability to blend the back curve to a minimal thickness.
Asymetrical, horizontal symetry, variable near inset, PRP to DRP of 4mm (for consistency), and a partridge in a pear tree. :D
Maybe a hard and soft version, or a near emphasis and far emphasis versions.
Spherical front, variable corridor length AND width, capacity to weight the pwr change as needed through the corridor (ie: more area for intermediate than near, and the opposite), ability to blend back curve with opposing curve to minimize thickness (Similar to an old blended myodisc). And finally a desk top machine that creates the lens and edges, run by the equivilant of a glorified dremmel and a vacuum.
I vote for keeping the PALs as they are, and re-inventing our patients. I'd want one of those things from the movie 'Men in Black', where you shine a light at the patient, and wam!, all the bad things that their cousin's aunt's neighbor's son told them about progressives would just blow away, like leaves in the fall.
Spherical front, design fully back surfaced should be possible, at least from a design standpoint. I think the biggest issue is getting someone to make a generator to cut it.Quote:

I think a PAL that would benefit customers the most would be one that was generic, anyone with a freeform could make without click fees to anyone. Then ultimately progressives would become just a lens type. They would not cost nearly as much as now. You know a progressive is as cheaply molded as SVs and easier than flat tops. When the orders were made you would just request a progressive. It would be just another lens type on the RX. Not 14 different choices on the RX. Practitioners would then be free to chose without perks from manufacturers clouding their judgement.Quote:

I check it everyday! My plan and purpose for this thread was to get what you; the Opticians wanted in your lenses, my interjections may have served only to poison the pot. By looking at what is found here we can get your input on shaping the destiny of the next generation of lens designs.
Hi, we have been producing Free-Form slaboff lenses for about 3 years. Your wish is grant it! Send your Free-Form Rx any time; Paqnto, Facial Form angle, and Vertex Distance will be helpful.

...I meant granted :)
Well, I also meant panto. I think it's getting late, the happy hour is on.
It would be free of all distortion and abberation at all points. Would require little diversion from center to reading position for most of add power to be achieved. Cost me $10.00 and sell for $200.00.
One that would work well for distance and intermediate, no near, extra wide.
Yes I know you can putz around and do that with the Sola Acess, but the distance Rx range is too small. This would be used for an industrial computer that someone uses mostly while standing above it.
Shamir Free Form Office. What Rx range are you looking for?Quote:
