hello there welcome to the clinic.
So I want to show you some more colour vision tests that I've acquired.
This is the first one I'm going to be showing you today
usually for this test
it would be performed at 75 cm, natural lighting conditions and you'd have about five seconds
per plate to give your answer.
So the way it works is, I'll show you the plates and you're looking for an interruption
in the shape, you need to point to but without touching the page or say up down left or right
where you see the interruption there
okay just go from left to right
excellent just continue like that please
the beauty of these plates they can be rotated
again just point to or say where the interruption is there so it would work
okay if you're seeing two interruptions there, which one would you say is a colour variation
and which one is the true interruption?
and the next one
okay just keep going please
and just continue
excellent
and the next one please
Okay now the target is getting a little smaller here, on this plate
don't touch just point towards and say
okay we're on to the final one now, looking for the interruption again, in the shape
excellent that's Ohkuma's tests card or coloured efficiency there thank you.
Okay the second colour vision test is very fascinating, you actually don't have to give
me any verbal responses for your testing on this one.
here's the details of the test if you're interested
by Professor Karl Velhagen and what you're going to need
is this devils fork here.
I'd like you to hold it by the handle like this, now I'm going to show you some tumbling
E's on the plates, I would like you to match the direction
by rotating the tumbling E, to that that matches the plate please.
I'm going to give you this there thank you
Lets get to the start of the test
okay if you're ready, just match the direction of what you see
on the plate there please
excellent
okay here is plate two
good
Okay and four
marvellous
right we're on to six here
and this one please
good
Okay nine can be a little bit tricky just take your time
to orientate the tumbling E to match this on the plate please
there is ten
and eleven
and twelve please
keep going, doing very well
now we're on fourteen
and fifteen
coming towards the end here
a couple more to go.
I've got sixteen for you
that was the last one 16 plates.
that's that one completed thank you.
Let's move on to the next one
iHere's the third colour vision test I'm going to show you, quite a bit of wear and tear
to this one
it's an old piece.
So your job is to say the number that you feel you can see.
Say if there is no number there and where directed, I want you to trace the pattern
with your finger but without touching the plates.
So say numeral you see there please
and the bottom one is an example of just tracing with your finger without touching
excellent
try my level best not to touch the plates.
Let's start top left please, saying any numbers that are present
and this is the order, I want you to go bottom left next
and then we go top right
and then move to the bottom right plate please
excellent
and the one below
and now for the top right plate
okay nothing on those two?
that's normal thank you
another one of the finger tracing plates here, but now touching of the plate
and for this bottom one, which has faded a little
that's good tracing
and do you see any numerals and this one?
and any numerals are on the bottom one there?
okay your top left here
anything on the bottom one there?
thankyou, and for this one
and then we present this one
okay numeral identification again if any are present
and same there
this one do you see a particular number there
and this one just trace please with the finger but not a cheek
and for the final colour vision test, very simple this one, I'm going to use the coloured
paddles which you've seen before and enjoy very much, this distance, what colour paddle
do you see there?
and then the reverse please
and there?
and identify that one excellent
and there and there please good
I'm going to make the
paddles increasingly smaller in area
there please and identify there good
excellent
lovely
now for the smallest target, just identify the colour if possible please
thank you
excellent.
In fact just to finish off let's do one more just simply pointing to the colours I ask
for on each of the three rows
okay on the top row please, this row, please point to the red block, point to the green,
point to blue and point to Yellow
okay on the middle row identify green, red, yellow and blue
And for the final row, yellow, red, blue and green.
In fact let's just rotate.
Top row here.
I would like you to point to green
I'd like you to point to Red on this row
excellent this row blue
and then red, on the third row Point toward yellow
okay now green, blue and red and for the bottom row point to red, point to green, point to
yellow.
Marvellous, so that's all the colour vision tests I wanted to show you today, just remember
that this was just show and tell for ASMR purposes, doesn't mimic the true conditions.
Any concerns with your colour vision, you must have your eyes tested by an optometrist
thank you
