Eye problems stop 3D-movie fun

As 3D movies become more popular, it's becoming more apparent how many people have vision problems and suffer from symptoms related to depth-perception problems.

As people crowd into theaters for the latest wave of 3D movies, everyone seems to be oohing and ahhing over the visual feast provided by Hollywood's improved 3D technology.

Millions of people have vision problems that keep them from enjoying such 3D movies as Avatar and Toy Story 3, estimates the American Optometric Association. And as many as 56% of people between 18 and 38 years of age suffer from symptoms related to depth-perception problems.

  • Amblyopia, or lazy eye, which occurs when one eye does not see as well as the other. "Because of that difference between the two eyes, the ability to see 3D is greatly reduced or absent," Maino said.
  • Strabismus, or crossed eyes, in which the eyes do not line up in the same direction when focusing. Ultimately, a person with strabismus begins to suffer from double vision or loses the ability to see in 3D.
  • Convergence insufficiency, in which the eyes are incapable of turning toward each other to fix on the same distance.
