I was always in the last group. I'm curious what group those who describe the background of an LCD screen as not appearing solid might be in.
I'm obviously ignoring the 4th group of people who tended to lie about being able to see the optical illusion and then walked away.  |
I have a vague memory of the pictures you're talking about but honestly can't remember if I was able to see the illusion or not! Though I'm thinking not.
EDIT: found this article that says people with convergence issues who have difficulty merging two images into one have trouble with stereograms. I do have this difficulty - my eyes only work together properly if I am looking straight ahead. Otherwise I tend to default to my better eye and ignore the image from the other eye. So maybe I would be able to see the illusion if I looked at it from exactly the right angle....
