A few years ago, these were all the rage, and I was even bought a book of them as a present, and 'saw' them all! They were great fun, harmless, and I had a sneaking, smug feeling that my eyesight was pretty damn good for that!
Nowadays, wearing glasses with all sorts of lens strengths in odd places, and a price tag of £400 a pop every couple of years, I've lost all that - until now...

Now I really can 'see' something here, I suppose it's a basic primary colour refraction element (what on earth are you on about Scrobs - Ed)? But the blue background with the red lines are definitely in 3D...
Or are they...

I'd forgotten all about autostereograms. As I remember them, I usually had to take my specs off to see what I was supposed to see. Can't see much in the graph either way. Maybe I need my old gold-rimmed specs.
It does seem to be a result of specs making it difficult, AK, your pince-nez may well solve the issue...
I found that the best way for me to see them was to look at them cross eyed rather than the looking into the distance thing.
Of course I then saw the image in-side out, What should have been nearer appeared to me as further away.
Incidentally, the cross eyed viewing trick is an excellent way of quickly doing these "Spot the Difference" puzzles. Just get images superimposed an any difference shows up as a blur.
I've just tried the crossed-eyed method, D, and I still can't get it to work!
I'll try it out on a spot the differnce when I get the paper...
