HELP !!! Is it possible to slab-off a progressive lens?? Customer just called me (at 6:30 AM) and needs to know if it is possible. I need HELP from those of you who have experience with these things.

Yes. No problem. Actually, most labs have ground at least a few. They are not as common as flat top slabs. Anyway, your lab should be able to do this nicely for you.

You should consider an AR coating, since it will make the slab line less obvious (which is particularly important for "no-line" bifocals).

Best regards,

We have sold a few slab-off progressives in the last few years, and even with AR coating, I was disappointed in how they looked. A flat top hides the slab-off better, but as a progressive wearer, I guess I would still try to stay in a progressive, and put up with the cosmetics, if I had enough visual change or a surgery warranted a slab-off for me.

Should be no problem, we have fit quite a few over the past few years too. just be sure not to fit them too low...

Just got the slab-off back from the surface lab and I have to agree with Jenny P., it looks horrendous. Next time I'll try to talk the Dr's into using a flat top.

My sister in law wears a slab off and a progressive lens. She wears the Panamic with Crizal ar. Her one lens is a +3.25 and the other is a -.75. The lenses look fine(well as fine as lenses with that much difference can look). The line is very faint.

She has had no problems at all with them.

We recently made a pair for a patient in a Gradal Top with Zeiss AR. The slab line was very apparent when holding the glasses out, but when anyone put them on, and an observer was looking for the slab line, it couldn't be seen, unless you got 2 feet away from the patient (slight exaggeration, but you get the point).

The only problem I had was the patient wouldn't use them. We ended up nonadapting her into the same progressive without a slab.

Oh well, we tried.
