Hello and welcome to the clinic. So we have our patient seated here, we're going to be taking some
technical measurements uh concerning the face, for bespoke spectacles or just for some general asmr,
or to just discover the patient's configurations.
Don't worry about your induced parallax the patient and eye are on eye level and we're both
square on there. We're going to be using this ruler here, we have the pointer there,
cursor here, some technical scales here and here, a little scale there and protractor scale here and
the apical radii scale there. So I'll try and utilize the full features of this ruler here
today on the patient. So the first measurement is an interpupillary distance one. Okay madam
we're going to measure from the centre of this pupil to this one as you're looking into my eye.
Okay I'll rest this here, there we go heads steady, looking into my left eye, right eye
left and right. Looks to be 59 millimetres there thank you.
Just try a monocular measurement, left here
Just utilize the other side there. Super. Looking into my left eye, that's approximately
29 millimetres there, okay, so the full distance and the monocular ones there. Okay moving on.
Okay let's ensure that the scale is set up correctly there. This is a DBR measurement,
distance between rims, I'm going to do it at 10 millimetres below the crest
and 50 millimetres below the crest. Let's start at 10.
Going to place this here madam.
Just bring this in for you until you have just slight contact
at the side there. Just measuring off that scale there
and then just at 15 below.
There we go. That's an interesting measurement it's based on the shape there, your nose goes in,
so that's actually a little bit less than at 10 millimetres below the crest.
Okay I shall record that and move on to the next measurement.
Okay move the cursor. I'm going to do something called crest height now
Start here, align this part with the centre of the pupil and we'll measure down to the lower
lid. Just look it into my right eye. Alignment is there, nicely on the crest
and it looks to be about nine millimetres
and one at five to get 14 mil there.
That's for the left. Switching for the right now, just looking into my
left eye now
and the reading on the scale here is about nine plus five, fourteen mil. Super.
Okay, apical radius time. We're looking for a snug fit
on the bridge there. Start high, work our way down
still too big, eight, yeah slightly too big with an eight, seven
it's fairly good, let's go to a six
seems to be a little bit more snug on the six. Just double checking the five, that's too narrow.
Okay so six seems good, seven a little bit too big so I, think we're going to go between the two
that's 6.5 mil with the apical radius.
Okay madam, turn to your right, going to judge the bridge projection, looking at the eyelashes,
they are behind the crest there.
Positive on the right side and turn this way. Checking here and a positive on the left side.
Okay
we need to bring the cursor into play now
I'm going to ask you to lean forward
to about there and place this on the crest there
bring the cursor forward until we just miss the eyelashes there
okay, lovely, I'll record that
okay, back to your square position, facing me dead on
okay we're going to be utilizing the pointer now
this measurement is the frontal angle, the right side and left the longest line
right in the centre here, I'm going to bring the pointer
to about there, where we have initial contact. Going to read from the protractor scale,
so the frontal angle on the right side is just shy of 20 degrees
on the left side
okay a little bit narrower there, just around
12 to 13 degrees on the left
Same principle, pointer on this marking here
forward a little bit this measurement is known as the splay angle, that's splay
yeah we're going to come from an angle here bring the pointer in, just missing lashes
to there, using the protractor scale 20 degrees on the right side
for the left side
just miss lashes a little bit and we have about 22 to 23 degrees on the left
Looking to the right side there, length to bend and angle of side measurement now
okay iIm going to place this just above the ear there, to mimic the frame angle,
just bring this in here, so you want a square angle there, just missing the lashes. I'm going
to take the measurement to about there, 100 millimetres and the angle created here reads as
eight degrees, sorry 18 degrees madam, beg your pardon, um
let's try length to tangent while you're looking that way
downward angle of drop
30 degrees okay
okay two two right side measurements on the left side now, repeating what we've just done
about there
20 degrees
thank you
and length to tangent
and we have about 23 degrees there. Okay facing me, square up
I'm going to measure your head width now
I have to bring the second rule into play as a marker. Just relax.
Square on there
it's about 133 mil
and for the temple width now, similar principle
should be less than head width, 110 mil
okay madam. I see you've selected some beautiful frames, which you're going to order with your
bespoke measurements. Let's have a look at the stock frame on you. It's a lovely choice,
two-tone colour, full plastic, little comfortable little projections there.
We can have a look at the length to bend once the frame is on
Okay. so they're going to be sitting about there aren't they madam?
Okay, I'm going to take some measurements for the bifocal now the frame is in place
It's called the segment height, going to utilize this scale here. Okay, just keep your head steady,
looking into my left eye there. From the lower lid we go, to the bottom of the frame
11 millimetres on the right. Looking into my right eye, lower lid to bottom of the frame
there, 12 millimetres. Let's utilise this scale here.
This is the segment top position,
to align these nicely there in the centre of the pupil. Looking into my right eye
two millimetres below horizontal centre line
looking into my left eye. Same thing on the right side
reading of three millimetre below HCL
another pupillary distance measurement with those on
looking into my left eye
and the right eye, left and right. Thank you. Okay, turn to your right side
Going to measure the length to bend measurement there
and we will when your frames return, adjust the length to bend,
so have a little bit more snug fit behind the ear there,
that will avoid any excess rubbing against the mastoid processor. Okay to the right side we go
let's have a look at the length to bend on this side
Okay let's record it and again, on your bespoke spectacles we'll have to bring the
angle around here, the bend for a more comfortable fit.
So I think that's all the measurements madam, we'll give you a call once those
bespoke spectacles have arrived. They'll come back with the prescription in place,
so you have an optimum fitting frame and optimum vision. Thank you for coming in today.
