Can You See Two Images ?

[Alex]

Took me ages to see these....

I've seen that before. I solved it in seconds

That's weird, isn't it.
If I let my eyes sort of relax and go dreamy,  Yes, I can see two images briefly.

I can do that too.  I simply relax and don't concentrate on the image.  That allows my eyes to return to the neutral position pointing directly forward.  In other words, relax and don't even think about the image.
I'm very good at relaxing!

You have to tilt your head slightly right and squint a bit

I don't think anybody noticed. They are probably looking for 3D or something.

Defocussing certainly helps.

 I've defocussed and relaxed and gone dreamy and tilted my head to one side.

I can still only see one image.

Well done!  I must admit that I had never noticed that until your comment.
