This was my understanding of it as well, yes.
As Robert (S, not M) has mentioned, during blocking, the view of the blocker mires through the lenses are displaced by the prismatic Rx, and so we...
Old but gold, a thread about this particular type of compensation, with input from the late (and great) Daryl Meister:
Fitting PALs with prescribed prism
TLDR: compensate the centration by 0.3...
I find it more helpful to think in terms of intermediate addition in 0.25 DS increments first, then their corresponding distances. As drk has noted, it gets the job done :)
In terms of how much...
I often dispense all forms of blue cut lenses (coatings, in-mass, and indirectly via photochromics) to patients, with the following caveats:
- I do not make any claims about the alleged health...
Essilor (via Bernard Maitenaz) may have designed the first commercially viable PAL, but Dr Estelle Glancy may have prior to that been the true designer of the first PAL.
Varilux Comfort (including...
Solid advice already given on the lens correction options and how to go about that.
Having dealt with similar patients since these sorts of implants became popular (almost all of which eventually...
Agreed on the hyperopes favouring soft design bit, that's been true across the board for all manufacturers and designs.
Regarding the CL wearers thing, doesn't seem like a price point factor......
So, my trusty old Heine streak retinoscope has died after 10ish years of use. Got it at a decent price back then by sharing a group purchase with a group of optometry students, but current prices are...
Sounds like a plan, and if all else fails, maybe reconfirm the axis changes (since she's after all a keratoconus patient) :)
Personally, for all higher minus cases passing through my dispense, if...
IIRC, prior to free form designs, when it was all molded front surface progressives, then the location of the PRP was more relevant for various reasons, including pantoscopic tilt calculations etc as...
So, my Zeiss rep visited, polite as always, and due to some recent increased turnaround times for edging jobs by my usual Essilor/Hoya labs, I'm taking a second look at the Zeiss progressive lens...
Also, just noticed something that may be related:
Am unfamiliar with this particular variant of Varilux Physio (since locally here it's just the default Varilux Physio and the Varilux Physio Fit...
Unsure about how the Rx compensation on this particular Varilux Physio design is done, is it possible the sizable axis changes could have led to this patient feedback?
Also, given the high Rx, any...
W.r.t the OP: IMHO Eyezen lenses are as good as any other free form anti-fatigue by a competent lens lab, just take note of the specific addition powers available and the 4 drop (different to say,...
So, with a pleasant year end (belated Merry Christmas and a Happy New Year to all) behind me, and the dust settling from the usual colourful state of affairs called annual close of business... :)
...
For segmented multifocals I'd agree, that's also how I was taught to verify them, convex side facing down. Reading distance and near Rx separately, then deducting the difference to get the add.
...
Seconded (though from your informative posts over the years, this is hardly a surprise!) :nerd:
Blended lenticulars are something I have almost always failed to switch existing conventional...
Might be a regional/geographic variation in product availability, but as far as my local reps tell me, Essilor/Nikon lenses in Southeast Asia all have the progressive optics on the back surface, with...
Late to the game as always but as an optometrist who has happily dispensed many pairs of Varilux S (2015 - 2018) and X (2018 - present), with mostly good results, here's my observations on these two...
I once asked a senior lab tech this question (a gentleman from a machinist background who worked production for many years, and whose optical knowledge, while formidable, was largely self taught...
Thanks all for the responses! Been overwhelmingly busy the last... days, a happy problem to have.
Now, back on topic:
@ Robert - Most helpful, that's where I saw the source of my confusion, the...
Maybe I'm overthinking this one, but here goes!
So I was having a pleasant catch-up with a gentleman who works for Hoya, and we ended up discussing that golden oldie, the Hoya ID. Specifically,...
Have two pairs as follows in my personal Rx:
1.60 Transitions Xtractive with Silver Mirror coating
1.60 Sensity Shine with Silver Mirror coating
Both pairs have the base photochromic colour as...
Having dispensed thousands of poly lenses, from stock to premium free form designs, I have not noticed significantly more complaints than I get with any other lens material.
I believe it's because...
