Fitting height issues abound with variable corridor length designs. Choose shorter than the fit suggests and you narrow the intermediate, etc. I prefer to choose my own, based on wearer usage, rx,...

I'm going to turn this upside down. First time progressive wearers should have two things: No real perception at distance that anything is going on, and since they are younger, usable reading way...
Part of the problem may be the choice of an essilor short corridor lens: some are digitally surfaced, presenting a whole different set of optics from back surface designs. Many Hyperopes don't...
I've been using Seiko perfas lenses for years (mostly the same as succeed and supercede, just house branded and produced in Minnesota). the quality is great, and the ability to choose corrdior...

why waste your time? Just carry a 3d printer with you..
I heard some scuttlebutt, from a US based Union rep, that UL in foreign countries is about as useful as their products. To wit, Chinese UL approval would not stand up to US inspection...
Makes you...
Yes, Barry, thats what I was lookin at..but is Vx actually thinking a compensation for rx or for imbalance?
um..has this person worn bifocals before? Ever worn slab-off? Methinks maybe VX program sees whats goin on..
You seem to forget the cost of just "being there". Your overhead is exactly what consumers avoid paying for when they buy online. An accountant would say that your cost is the materials PLUS your...

Seriously, it's polyurethane, it's not "healthy", but you're not edging hi-index all day unless you're in a lab..
Never assume you know a customer's budget. Always PROFESSIONALLY assess what wil benefit your patient, recommend the options, and let the patient tell you if there is a budget issue. Would you not...
Yes, as far as actually FILLING the RX, the presence and retention of the DOCTORS signature on the proper form.
However, I am not loathe to fill a spectacle RX (or have one filled) by verbal...
Watch your lens choice, and yes, do it by decentration. By lens choice, I mean SPHERICAL, NOT APHERIC! (always when ordering prism). BTW, the prism is out of range for digital surfacing. Seiko has...
The article claims that because millions are wearing it, it must be ok. You must be aware that millins of Europeans wore single layer AR for years. It would not fly here in the US because we don't...
I've been using custom corridr length lenses very successfully for early presbyopes. Consider the height at which the near vision is used.. a 14-16mm corridor lens works well with low add power for...
I don't think that will create prism , just the corridor in the wrong place. Zeiss's variable inset is to be used when you measure a near pd....
I asked the same same question of my rep, who responded that the Reveal is designed with a wider intermediate, the GT2 3D wider distance (harder design??).
The Reveal FF is corridor adjusted to...
Verify the relative fit of the the two pairs (panto, wrap, vertex, base curve,etc). Remember that increasing panto is like dropping the oc. Also check the amount of prism thinning. I've found some...
My shop in is Windsor Terrace, Brooklyn. It's a short subway ride, half a block from the Prospect Park West F train stop.

google it..easy trip by subway an I'm always glad to...
Ok....this RX has ANTI_METROPIA..plenty to throw off near vision in a progressive.
How to fix?..
Autograph 2 11mm fixed corridor, and order a base curve close to his old pair. They will feel...
Zeiss coatings are not as durable as Crizal. However, they are still way better than an uncoated cr39 lens, which is to say if they get scratched, blame the consumer (gasp).
Why don't you try some digital lens designs? Quite a few all digital labs have inexpensive offerings, and unless you're fitting a high hyperope they all work fairly well. They also usually have a...
You can get Serengetti lenses from Zeiss, and they can be gradient tinted. ODG supplies the same product without the serengetti label, it's trivex NXT varia copper. It can be gradient tinted and is...
It's Manhattan..getting around is a *****. Plus, I'd say half the guys actually working in NYC aren't licensed anymore.
Why don't you call up Warby Parker, since they're so community friendly, and...
In the us the equivalents have not been released. Im not shure u.s. opticians would make enough use of it for seiko to bother with. As it is the choice of corridor lengths is poorly applied.
