They would have pre-dated the use in the US of metric sizes I seem to remember that the larger (temple) screw would be the equalivant of 1.37mm.

CaliforniaCareForce.org can use them - we do clinics with refractions, new frames and new lenses (unlike Lion's which use donated, used glasses that approximate the patient's Rx). Our next clinic is...
Total minus is similar, but wild axis changes, especially OD. Posture changes produce angle changes which simulate cylinder axis changes.
If the old axes were wrong, and the new ones correct,...
on the subject of "spot heating" - when I do clinics for CaliforniaCareForce.org (sorry, I had to sneak in a promo) I have only a hot air blower but I rigged a very small funnel upside down over the...
get a salt pan and a spoon - it worked great for the 50 years that I dispensed - you have to dissolve the salt out of the nooks and crannies, but you're going to wash the lenses anyway, right?
to make it simple - the image moves toward the apex of the prism, not the base
Sorry if this is too late to help - Suspension Eyewear
As suggested above, some lab experience, and solid classroom learning-BUT-may not be realistic in a business where someone is the receptionist one day and the contact lens fitter the next (I have...
Steve, thank you for keeping OptiCampus and its wonderfully useful calculators available. Even in retirement, I find ways to steer new Opticians to them.
I didn't know of your relationship with...
ANOTHER BUMP
We at californiacareforce.org have our 2023 clinic schedule at last, and would like to cajole you into joining us - we need ophthalmic pros of all
persuasions, in particular...
Remember Suspension Eyewear? A rimless front with nylon monofilament lines reaching back to hooks (a bit like cable-conversion tips) around the ears.
I think I still have one somewhere, and I'll bet...
I agree, once surgery becomes indicated, it's too late to use contacts to experiment and choose an IOL.
Has anyone here had patients who were successful with monovision contacts but not monovision...
Years ago, knowing that IOL's were in my future, I tried (for a reasonable period, not just a day or two) both monovision contacts and multifocal (simultaneous vision) contacts. I had had patients...
You are a hyperope and/or presbyope. You cannot read without your reading Rx. You are wearing a virtual reality device. The display shows a distant landscape, but the image is in fact a few cm from...
Also, make any bends in the pad arm with a round-post plier - if you use an ordinary snipe-nose with square-edged jaws, you'll get a sharply kinked bend, which will weaken the metal
Why not just replace the hinge? You may need to use visible rivets the old-fashioned way, but you can adapt (machine and drill) a hinge from a junk frame to match and
hammer it into place. Or is it...
Wasn't this a King Crimson song ?
First of all, congratulations on your success - and yes, take the advanced just for fun.
Second, I'm one of those people who nitpick about grammar and misused apostrophes, and 12th diopters when...
A/R doesn't add anything positive to night vision, it just aims to reduce some of the negatives of having lenses in front of your eyes.
A/R purports to enable transmission rates of 99% or so - no...
[QUOTE=IIxIPariahIxII; I feel like 8/10 times it's something with the glasses, not the RX.
It's almost never the refraction. I worked my last couple of years for an MD/OD practice. Their patients...
Just getting the power and PD correct is the easy part - no report of that sort can grade fit and adjustment, proper choice of lens type, instruction and expectation management, and the...
I don't believe anyone is allergic to gold (I don't mean 14K, alloyed gold) and very few to silver (again, pure silver). An artist supply store would have 24K gold and silver foil - wrap that around...
BUMP AGAIN
We have our biggest clinic (finally!) scheduled for Coachella March 25,26,27. The fun actually begins on Wednesday and Thursday with set-up; putting out frames, arranging tables,...
And dengue fever and the yaws are natural.
Sure, it's natural, but is it organic?
