With 3D enjoying an unprecedented popular resurgence — thanks to movies like James Cameron’s Avatar, and recent breakthroughs in home 3D technology like 3D TV, 3D Blu-ray, and even 3D Gaming systems like the Nintendo 3DS — there is still one rather glaring downside to the revolution.
For many people, the need for 3D glasses to enjoy it can be a real deal breaker. Although they are getting better, 3D glasses can still be both uncomfortable and expensive (especially if you have lots of friends and family).
Fortunately, there now exists technology that allows for consumers to enjoy 3D TV without glasses. Breakthroughs in 3D TV center on parallax barrier and lenticular lens technology, and use what is called autostereoscopy (or autostereoscopic screens).
Although 3D TV without glasses is still a rather young science — with Toshiba introducing the first 3D TV without glasses model only late last year — further breakthroughs (including holographic technology) are widely expected. Currently, the main drawback to 3D TV without glasses is the need to sit directly front and center of the set to get the full-on effect.
