Right, okay, so we're going to do a little bit of a catch-up test, it's been a few months
since I saw your last, colour vision because
you take medication that could cause an acquired colour defect,
so we're just going to monitor things again. So I'm going to start with the Farnsworth test
Okay cover your left eye with the occluder there
Okay so do you remember this one? Yes.
You have to select a cap that you feel closely matches the colour of this one, take your time
Let's have a look at the results
Okay while you're waiting just swap the occluder to the other eye
Excellent
So that was the right eye
Perfect score
Okay just close both eyes for me now
Okay and open, the right one is occluded, just ensure it's
fully blocked there, okay same again, left eye, take your time
Excellent, happy with the responses? Yes.
Okay
Just have a look, looks good to me
Excellent, perfect score right and left on the Farnsworth
Okay leave that eye occluded, we're going to do the Ishihara test now
Okay just say the number you think you see on the page

Looks as though your colour vision is holding up, that's a good sign.
Right so we're going to do right eye City University test
I'll just have a look at the previous results
Okay we're gonna go left to right, left to right,
does one of the spots there look different in colour or do they all look the same shade?
They all look the same. What about there? The top one. Top's different there?
They all look the same. Okay. The middle one. Excellent
They all look the same, the top one, good, the top one, and the middle one. Excellent
They all look the same, the middle one, the top one, they all look the same.
The bottom one, they all look the same, the top one, the middle one. Perfect,
okay now you're going to see five spots, now your reference spot is the centre one,
pick one at the side, top, bottom, left or right that closely matches the colour of the middle
Top. Good so that was the demonstration, now for the real thing. Right, good, let's move it there

That's it. So I'm pleased to say you've passed all the colour vision tests,
each eye. Not showing any signs of an acquired colour defect, brilliant, so I'm going to
review you again in about six months, see how you're getting on, that's everything, thank you
