People who are thinking about purchasing a new 3D television might want to get their eyes checked first.

Doctors at Northwestern University and the University of Rochester warn some people may experience severe headaches.

The technology has seen a surge of support lately, from the success of the Avatar movie to the unveiling of new three-dimensional television sets.

Still, even medical experts admit no official studies have been done to determine just how common headaches are when watching 3D.
