You can’t make me. I’m never gonna.

[chenille]

I tried but have to give up. I feel let down.

Saw that on tumblr earlier; saw dude both times

[OWYAC]

I see it; it’s very faint though.

[Millie_Fink]

VERY faint for me. Some dude in a suit, maybe? Makes me wonder if my color blindness is a hindrance (let alone what the point of that meme could be).

@Millie_Fink

Some dude in a suit, maybe?

Yes, a very particular dude. Other comments hint at who.

[Docosc]

I think it’s flipping me off!

ETA: OK, I see The Fonz!

[Millie_Fink]

What is it about our eyes that this “eye test” tests?

@Docosc

I think it’s flipping me off!

I just about see a shadowy shape.
Maybe it’s a thumbs-up Fonzie?

[Heikki]

Now see it kinda. I had look at it on 3 different screens.

[kxkvi]

Discrimination of different levels of brightness?
I did some quick manipulation (greyscale then adjusting histogram for more contrast) and got this (I used spoiler; I didn’t blur it!).

I probably lost information and added & amplified noise. But I don’t see the Fonz in either this or the original.

[OhHai]

Whether your eyes have spent time calibrating your display or not?

ETA: not meant to be directed at you, personally, I just meant that it seems as much (or more) of a display test as an eye test.

Whether or not you’re terminally online.

@1000YearBan got it right.

[Docosc]

In that one I def see The Fonz! C’mon man! Winkler FTW!

(ETA: Even with the “correct” answer, I will stick with mine just 'cause it’s less cliche!)

[Dogbutler]

Spot on, Doc.
Bleedin’ obvious, really:

Sorry for the crudity of the addendum.
(First time using Inkscape).

notsomuch

[Dogbutler]

I was only joking but, shit, apart from the flick-comb, not easy to see much difference, is there?
