20% or so of people have a deficit in stereo perception and don't benefit from 3-d movies, video games and stereograms. Some of those people experience significant discomfort from 3-d media.
It is a serious problem for the 3-d cinema as it reinforces the multiple-screen business model. Having 3-d and 2-d versions of the same film in the same theater with a $3 higher ticket price on the first one appeals to the short-term greed of the exhibitor but more importantly it creates a perception of greed on the part of the moviegoer. Look closer and you realize though that showing the same movie on two screens tends to be a money loser.
One can imagine an alternate world where all movies are produced and exhibited in 3-d, where moviegoers have learned to be enthusiastic about 3-d (often it is striking in movies that are not special-effects focused), where production in 3-d is normalized, and people have a reason to go out to the cinema.
Stereoblindness, however, kills that dream and leaves us in the present where 3-d is perceived as a greedy gimmick.
