If 3D movies cause eye strain or discomfort, you may have a vision problem.<\/b><\/h2>\n

3D movies are becoming all the rage lately. Hollywood puts out more and more new 3D offerings in theaters every year, and an increasing number of television shows allow for 3D viewing as well.<\/p>\n

But if the 3D experience makes you feel sick or causes headaches, or if you simply can\u2019t see the 3D effect, this could be a sign of undiagnosed vision problems.<\/b><\/p>\n

Fortunately your local eye doctor can help.<\/p>\n

Binocular vision is vital to see 3D<\/b><\/h2>\n

The reason that 3D television and movie experiences work – or don\u2019t – is because of a process known as binocular vision<\/a>.<\/p>\n

In a healthy visual system, both your eyes are properly in sync, moving in unison to look at a certain object or point in space. Each eye sends visual information back to the brain, where it is interpreted.<\/p>\n

The two eyes working together and being in slightly different positions is vital for the brain to create 3D images.<\/p>\n

Binocular vision simply means the brain is using both eyes at the same time – which is essential for us to see clear and single 3D images of the world around us.<\/b><\/p>\n

3D shows and movies use two cameras, just like our two eyes, to create a double image on the screen, which allows your brain to perceive the movie in three dimensions.<\/p>\n

Back when 3D was first introduced, this was done by separating images into green and red wavelengths and having audiences wear red\/green glasses.<\/p>\n

These days the 3D is more realistic as the camera techniques use polarized light to separate two sets of images. Movie viewers use polarized glasses<\/a>, which look like regular sunglasses, to see the 3D effect.<\/p>\n

Why can 3D movies cause problems?<\/b><\/h2>\n

If you experience eye strain or headaches from 3D viewings, or simply<\/b> cannot see the 3D images, you may have a binocular vision problem<\/b>.<\/p>\n

The most common symptoms of discomfort that people report during or after watching a 3D movie or TV show are headaches, blurry vision, fatigue and nausea. In some instances, the show or movie doesn\u2019t appear in 3D to them at all.<\/p>\n

When the brain cannot combine the images from the two eyes, it works harder to try to create a single, clear and comfortable image – causing eye strain and other symptoms.<\/p>\n
