My boyfriend has had vertigo for two weeks now. it's seems to started after seeing a 3d movie. he gets dizzy and nauseous when he sees busy patterns. ?

Vertigo can be: due to ear infection or perhaps an eye issue since your boyfriend responds negatively to busy patterns. Start w/his family doc who may refer to an eye doc if necessary. Peace and good health.

See eye doctor : Two weeks is too long to still have symptoms. To see a 3D movie,U need good stereopsis or depth perception to enjoy it. If he watched it in 2D, or had one eye closed, he would not have such a large disparity between the angles of the picture relative to his angle of viewing not matching w/ poor fusion.This may have to do with his alignment of both eyes not integrating the images/patterns well.
