Ff round seg!

X-Cel has a FT28 in CR39 available with a +5.00 add, I know that's still 1.50 D weak though.

[snowmonster]

Just curious - a +6.50 add has a working distance of only 15.38 centimeters. What on Earth is this guy/gal doing that they need to look down through the FT to look that close?

Use a Franklin

Use a Franklin

I don't know why I always forget about this. I need a good article to read about how they're made/produced.

Can anyone help me with a link/article?

I just read this thread http://www.optiboard.com/forums/show...=franklin+lens and was left with one question - how do you hold the two pieces of lens together? Jacqui uses glue, how do the you do it (hold them together)? Or does the bevel just keep it in place?

Thanks!

Putting Franklins together can be quite tricky, but once you get it right its easier every time. We used to try always fit them into plastic frames. They have more "give" when you put the two lenses in. It is not impossible in metal frames, only more difficult.
Another option was to use the same glue used for diving masks and glue them together, but if the two lenses were very far apart in powers you could end up making a mess. You also then got to worrry aboy gluing them together and getting prism (base in/out) if they were not done perfectly.

Snowmaster, Will have a video that will describe and show this for anyone soon. Simple cheap tools,, mostly simple inexpensive lenses. Got to be willing to get your hands a little dirty and work in a little plastic dust.

Pictures and narative ready now, just waiting for me to put it together.

Chip,

I keep telling you that you need to do a lecture on something. You have knowledge to share and having had you in some of my lectures, I know that you want to do it. This would be the very thing. When you gonna do it, my friend?;)

I want a copy so I can find out what the difference is in our techniques. I know that you usually don't use glue, but what else is different?? How does Clive Noble's technique differ from ours??

Not sure what hes using it for. The doctor prescribed it and I'm thinking maybe hes a jeweler or something of the like.
Thanks so much for the lead.:cheers:

I remember back in the day when we did slabs by hand we used Balsa to hold the cap lens in place during the surfacing .

I thought X-cel or Vision-ese had them to +6.00 add

[snowmonster]

Transitions cuts off at +5.00.

I really want to see this. Please let us know when it's available, Chip.

Try a stick-on add from Signet-Armorlite. It won't change colors, but it can go on any SV Transitions, so the patient will get the benefit of comfort lenses.

Or a clip-on loupe.

I think X-Cel has some in glass that go that high, 8.25 and 10.25 BC, in PGX. I like the loupe idea.
