Avatar in 3D might cause visual problems in some people

3D movies are making a huge comeback these days. Moviegoers flocked to the blockbuster "Avatar" and were dazzled by the 3D images. However, for a small percentage of people, 3D movies can be a real headache. About 5 to 10 percent of people don't have true depth perception and even more have trouble with their binocular vision. These are needed to see the 3D images in movies. Strabismus and amblyopia are both eye conditions which can cause the person to experience eyestrain which can in turn lead to a headache. Strabismus is the professional term used when the eyes don't align properly when focusing. Amblyopia? is the loss or lack of development of clear central vision in one eye, even when using eyeglasses or contact lenses. Even people who struggle to keep their eyes lined up and moving together will have trouble processing the 3D images. People who have experienced trouble when viewing 3D images should consult their eye care professional and have an eye exam and have their stereoscopic vision assessed. Elise Ervin Staff Writer
