All our lens availability guides from a variety of manufacturers treat the sph as the max available power. The cyl tends to just be the max cylinder power that can be surfaced, rather than showing...

I'm wearing the individual 3 and I barely notice that the corridor even exists, it just all feels like good lens. And I have difficult eyes!

Guess whose vision has changed yet again!

I'm losing my mind with this.

Migraines are gone at least but now I'm R: -2.50DS L: -4.75DS / -0.50DC x 167

Using trial lenses to cancel out the rx until you are left with plano, and work backwards so you know the power of the original lens (e.g. +1.00D lens is neutralised by a -1.00D trial lens), all...

Read through a bit of this and on the very first page was struck by the fact that some people don't know how to do hand neutralisation?
That blows my mind.
I had an exam on hand neutralisation...

Agree with drk, maybe also measure canthus to canthus between eyes just to verify your other measurements.

I just wondered if anyone had any random but interesting (and potentially not even useful beyond entertainment) optical facts, be it lenses, frames. or equipment?

I love a bit of random trivia...

I find that so strange. This course is a(n interesting) nightmare, and while some of it is stuff I will just never need, so much of it is intensive knowledge that I need every single day. The idea...

So what qualifications are actually required to be licensed in the US? Here in the UK I am halfway through a three year degree to be able to call myself a Dispensing Optician.

We have about 15 patients per clinic. We have two clinics a day minimum, but usually have three, so around 45 patients a day, not counting the contact lens clinic which is separate.
However we are...

Everything I read here makes me think that to a lot of the US an 'optician' is what the UK would call an optical assistant. Are qualifications and registration/licenses not a hard requirement be...

From what I've read on this forum, a lot of problems can be solved with Dawn... Shame we don't have it in the UK, although actually I think its the same as UK's Fairy liquid? :biggrin:

I think we have about 10 different options for progressives, single vision, and occupationals. And by that I mean we have about ten different options for each type. Lots of range for whatever the...

Well the handwriting isn't fantastic but it looks like both right and left eyes are now DS.
So you are no longer prescribed any correction for astigmatism, and thus don't have a value for an axis

It's always quiet this time of year for us. The Friday before Christmas we had a double clinic and a grand total of seven appointments, one of which was a recheck. The year I first started, I spent...

Polaris?

Out of curiosity I've just calculated exactly how many frames my branch has.
1268 across the board
264 of those are our own corporate brand
132 are kids frames
204 are sunglasses
The rest are...

In my practice we have 'optical consultants' that handle a lot of that. Dispensing Opticians do too but we're outnumbered by the non-qualified (but highly experienced) staff.

This sounds fascinating. I did know that we only really see a tiny percent of what there is but it sounds like there is so much more to learn here. Alas, it seems the video isn't available in England.

We don't even have music - apparently it's not clinical enough.

Yeah its amazing how different it feels. I don't think I realised just how much I was straining until I'm suddenly not.

UPDATE!
The varifocals seem fantastic. My eyes feel less strained and I haven't had an eye-based headache in the week I've been wearing them. It's still the high rx, with a +1.00 add, but its been...

Deepest point of the eye wire, also known as lowest tangent. It can also be measured to below HCL (horizontal centre line) but the obviously isn't one of the options.

I feel you on that. It's interesting how things change and how they stay the same. I was just shy of five when this thread started lol.

To be fair it's actually pretty good. I was skeptical myself at first, but it's helped out some genuinely lovely patients and it's no fuss for them. They come in and say "it's broken!" We say "Ok you...
