hello there, welcome to the clinic, so today I'm going to take a full range of measurements
for your bespoke spectacles, just looking straight ahead, I want to start off with a
simple cover test
just ensure there's no strabismus
and checking if there's a phoria
all right let's just repeat that at near, looking at the tip of the pen please
very good
right let's start with some bridge measurements, i'm going to incorporate this element and
this element using the scales here and on the reverse there
okay just relax yourself
just bring the cursor in there
and review the measurements
and for the other side, relax
lovely I just want to repeat this measurement but a little higher up on the horizontal centre
line, keep relaxing
okay a good range of measurements there
let's take some angular measurements using this scale here and the integrated cursor
for the other side
so we're looking at about 20 degrees for the frontal angle.
reverse things, rest is just on the bridge here, it's known as the spley angle
that's 20 degrees on the right
and on the left
approximately 17 degrees there
just rotating the cursor
so we want a little transparent element there, the transparent element is going to rest on
the front
bring it so we just almost make eyelash contact
good
looks like a positive two there, let's just have a look at the eyelash projections
and for the left
yes we have positive projection there right and left, now let's switch rulers, this one
here is actually going to measure eyelash projections on each side
focusing on the upper longest element
looking at about seven millimetres
and for the left
lash projections
again looking about seven millimetres there so fairly long lashes, thank you.
okay we have this scale here some more nasal little measurements.
this is known as the apical radius, looking for a very snug fit, not too loose, and not
too tight, okay if you're ready
that's a seven, to the six a little tight, that's seven
eight slightly loose.
I'm going to take that as seven millimetres there
let's remove this
okay this part here, this part, just going to rest on the bridge of the nose, I'm going
to check the crest height.
That's within normal range.
and for this side
it's about seven millimetres there thank you
right, so we're going to use this device here, I'm going to check the distance between the
pupils, the inter-pupillary distance.
Just looking straight
let me double check that for you
about 66 millimetres there
right switching rulers again, this one here I'm going to use the uppermost scale to double
check the inter-pupillary distance again
66 again, now I'm going to take one at a time using these scales here for the monocular
pupillary distance measurement
33 and 33 so nice and symmetrical there.
okay take some side measurements now
check the angle of side
on the right there
good
angle of side on the left
lovely
check the length to tangent on the right
and length to tangent on the left
I have the length there, now I'm just going to take the angular measurement just behind
the ear
good 20 degrees there
and on the left side, what do we have there?
just over 20 degrees we'll call that 22
okay we're going to incorporate both of these measuring devices now.
I'm going to take head width measurement, again just relax
I'm going to go to
both sides there
and just repeat
130 millimetres
let's use the shorter end of the cursor
to take a temple width measurement
here, just relax
okay 120 millimetres there
right I have some tape here, let's just measure the head height
that's in inches, now for centimetres please
okay let's take some diagonal measurements
okay and just the head circumference, forehead level
66 centimetres there marvellous
right let's have a look what scales we have here.
I'm going to move on to the pupils.
We have this scale here for the horizontal measurements looking for any anisocoria.
let's also check the vertical pupil measurements.
I want to ensure that we have a nice round pupil rather than an oval one.
just look straight
move along the scale
so for the right six millimetres
for the left
six again
okay let's switch to the vertical scale here
and for the left
good, nice round pupils there
now let's use
maybe this scale here
to check the distance between the lids, this is the vertical palpable aperture
Ten mil on the right
and 11 mil on the left so slightly larger aperture in the left by one millimetre
right, I'm going to use this scale here to check the iris diameter
just continue looking straight for the right
12 millimetres.
And for the left
12 again, marvellous
right, I want to take some measurements
as you wear these spectacles, these are going to be your second pair, I just want to measure
where we're going to fit the bifocal segment in these.
I'm also going to check the
length to bend, so where we need to potentially adjust these so that they fit nicely on both
sides
just before we do that
let me just check the
height of the lens
31 millimetres
just confirm that's the same
that's 31 and just for the bridge measurement there
thst's18 millimetres
okay let's get these on you
let's check the inter-pupillary distance with the spectacles on
marvellous
for the near measurement, just looking at the tip of the pen
looking straight, I'm just going to mark the centre of the lens
each eye
let's have a look at that length to bend
so we need to adjust these
at around 90 millimetres
it's about the same on the left, marvellous
okay let's go back to this ruler, check the segment height on the frames, just looking
into my right eye
so the segment height is going to be
eight millimetres from the bottom.
looking into my left eye
eight millimetres on the left
now just one final measurement with the spectacles on
excellent so I have all the measurements there, I'll get your first pair of bespoke spectacles
ordered and the second pair will go off today.
I'll give you a call when those are in
