After Hrs... Help with Double D Seg info?

[HCMB]

Anyone know after hrs, if I can get a Double D Bifocal Seg in Poly? If I remember correctly, it's only available in CR39 or Glass... hmmm. Optician is requesting Double D, Poly, & Trans! Sounds like a dream!

Thanks,.

Yup, sounds like a deam to me too.

I am pretty sure it is only available in plastic clear, glass clear, and photogray extra.

You might be able to have something custom ground. The cost could be prohibitive. Something to consider is a quality press on seg. There are higher quality ones than the normal 3M 'lined' variety. Nice and clear.

Anyone know how to measure a DD?

With both hands!
HA HA
I couldn't help myself....:D

You could have Three Rivers Optical make you a backside double round seg in poly trans. Cost you out the wazoo though.

Just like you would measure a standard lined bifocal. Seperation is 13mm.

I once offered a guy a pair of DDs and his eyes just about popped out of his head. Unfortunately I fall into that range. I will never use that terminology again. Although we did have a good laugh.

Also they could take a FT and put a round seg on the top (or bottom). You could get Trivex FT28 Trans w/ a round seg.

That will work too.:D
Maybe they could come up with a blended flattop.Or (snicker) a blended Exec.

They already make a badass blended slab-off. Blend EXEC would be a can of corn.

Thank you all for your help!
(I love this site!!!)
Optowoman, I fall into that category too!:p I can just see those eyes popping out! Thanks for the great laugh... You too nickrock!
The guy ended up with clear cr39 DD. Didn't want to spend the big bucks.

Thanks again to all who replied,

I believe Quest does!
Talk to Mike!
I think he can do the segs all around the lens if you are realy want to!

a guy who wants me to make him an upside down progressive.
Anybody had any requests for this?
He wants to be able to see int./near straight on and do a little head raise for distance.

The Overview is discountinued, I believe, so you are going to have to either engineer an upside standard PAL (just get PD and height correct) and I believe edge them R 4 L.... OR! Perhaps talking to a specials lab like Quest who might have more experience in this type of lens.

Odd's are it won't work the way the patient wants.... So get ready for mutiple remakes, delays, and complaints.

Talk about a specialty lens... what kind of work does he do to need something like that?

Switch Right for Left as Adam mentioned when edging and don't mess with any prism thinning as it will create more headaches than it's worth.

Not to mention the fit is going to require a 6-12^o retroscopic tilt, so your are going to have to see if this is going to effect fit (mashing his eyebrows).

Post the Rx and I could at least give you the Rx to order if you want to edge it yourself.

[RA]

believe me I won't make this lens. It has reamke written all over it.
It's for photography. I told him pal's are a no go and DD's ar ehis only option. And he doesn't want them sitting up high.

vanity

[HarryChiling]

And he doesn't want them sitting up high.

So he want a short corridor upside down progressive. I don't blame you for showing him the door. Usually I just price the lens at $800.00 with no options and tell them it's ultra specialty. I figure if they are willing to pay it, then I'm willing to make it. Give htem a back story about the lenses being imported and your only going to get one shot at it, and just do a bunch of math on the work ticket.

Sell the sizzle not the steak. :D

[RA]

That's funny
Yea, it's the pt who wants wants wants but doesn't want to pay. He was sweating over his Davis copays so I'm not sure what he thought when asking for this type of product. :hammer:

The Rx should be comped as well, for instance:

OD -1.00 -0.50 x 065 +2.00

If you were to surface this Rx into a left lens then flip it upside down the axis now flops to 155.
.

Harry, I don't think it changes the axis turning the lens upside down. But you're right about using a left pal for the right side and right for the left lens for convergance upsidedown.

[obxeyeguy]

Harry, I don't think it changes the axis turning the lens upside down.

I also am confused by this, as its still the same meridian.

I'm allowed a blunder every now and again right. You guys are absolutely right. :hammer:
