Hmm... I was wondering why I had a hard time identifying the color blue. (Learn something new about myself every day)

Attempt 2
(I got lazy and only focused on the mistakes I made the first time)
= score of 0 in my eyes. pun fully intended.

I think the luma range of peoples monitors makes a huge difference too...

(I'm on a 21" Samsung something-or-other...)
You can also hold ctrl and scroll your mouse wheel to zoom in
Or lean back to see things as a whole.
I'm considering testing both eyes separately too.
Or not.
Probably not.
