Many of us suffer from mild to extreme discomfort after watching 3D content. More recently, these ill effects were further corroborated by online findings conducted by the American Association of Optometrists. Yes, experiencing 3D content may result in blurred vision, nausea and other health-related symptoms. Call it an open secret. For the money makers, this does not bode well for the entertainment industry who have been investing vast amounts of money in 3D tech.

Essentially, stereoscopy works by hoodwinking the brain into perceiving 3D depth by combining images with two different perspectives. On the other hand, our eyes are designed to track and focus on approaching moving objects as well. Since 3D visuals aren't getting any closer technically, our brains have to work doubly hard to override the sensory impulse, which in turn, may cause queasiness at some level.
