I have a patient who's Rx Read

Dist:
-0.25 -0.25 x 082 5 out .5 Down
+1.50 -1.00 x 162 5 out .5 Up

Near:
+1.75 -0.25 x 082 .5 Down
+3.50 -1.00 x 162 .5 Up


She went to lenscrafters... got the Rx's made and called me today saying she didn't like having 2 pairs. Now she wants a bifocal... to look up at her TV and see clearly. I don't think this can be done... even if we fudge the Rx a bit.

Any Ideas? Assuming it can't be done... how can you tell the patient this?

There has been much discussion on this in the past. Do a search for Franklin seg using the search feature.

You just make them with the distance RX and a +2.00

Have you verify the RX with OD yet? especially the "5 out" part. If all correct, have OD explain why "5 out" not in near RX, what can optician do for a pair "multi-focal' for this pt. Then you can repeat that to the pt.

She doesn't need the prism in the near. Her eyes converge and work well in the near. The best answer i found was using half a Fresnel press on prism on the top only.

If you go that route, put them 5 BI on the bottom at they'll look better.

Has the patient worn any bifocals in the past?? Surely Darryl will help us out soon on this one, Chris..

Note: make sure you quotes the words when search, otherwise you see too many irrevelent threads (i.e. "Franklin seg", not Franklin seg ). There are 2 great educational threads about Franklin seg.

motelska, Franklin seg is exactly what ur customer need.

For those dispense franklin seg before: Is there anything special about measure seght or near/distance pd for this Franklin seg BF lens? Which lab(s) offer such lens? at what price (approx.)? thanks

Using a fresnel segment on the top only may be your only option. There is a way to cement a ground prism for dist only, but lab people know more about this than I do.

Using a fresnel prism is one way to work this if you don't want to do a Franklin Bifocal.

There are also specialty labs that will do this work for you. Epic Labs (not precision) is the one lab that I know for sure handles this type of work. LC does have an account with them, because that was where I worked at the time when I had a patient with a similar rx. Needed 7 BO distance, but none for near.

We make several pairs of Franklin Bi's a week, this Rx is not that difficult. I would not use a fresnel as I don't believe the optics are as good.

My lab would cut this booger in half and put them together in a metal eyewire. I've asked my lab to do it, and they did a nice job. For some reason, they call it "cement seg". I've heard them called "prism seg". I guess "Franklin seg" is more correct?

P.S. They charge you for two sets of lenses, and the handiwork, so remember that when charging your patient. Don't let him/her off cheap.

Just be careful with the PD's and vertical center placement, both are very, very important with Franklin Bi's.
