thanks yorkshire fella is that the exact test you had
The style of the plates were exactly the same but the numbers were different to the ones shown in that link.
It's pretty much that if you get all the answers correct in that online version then you will easily pass the booklet version.
The doctor just holds the book infront of you and flicks through the pages while you tell him/her what numbers you can see.
a 30 second test is all.
The contrast and colour saturation setting of your monitor may make some of the numbers hard to see in the online version so it's not a wholey accurate test.
I personally can see all the numbers and wiggly lines quite clearly though.
