A great white shark in your face, a Formula 1 race happening all around you. When you wear 3D spectacles to watch 3D movies on TV or a big movie screen, it's as if the action on the screen is going on right there in the room with you. It's an amazing visual experience, but just how does it work?
The human eye is perfectly designed for 3D vision. The distance between our eyes, about six and a half centimetres, plays a crucial role here. 3D movies work based on the biological fact that our two eyes see different images. We cannot see three-dimensionally with just one eye. Our brain has to put the two images together before we can see one three-dimensional image. This is how we are able to perceive depth and distances from different perspectives.
3D films on television or the big movie screen attempt to trick our mind by imitating the sophisticated technology of our pair of eyes. This only works if the cameras record two parallel images at a distance of exactly 6.5 centimetres apart. This might sound complicated, but it's actually technology that's been around for 150 years. Such images are also called stereoscopic photos. 3D movies are the next logical advancement in this technology. To get the most enjoyment out of 3D movies, you need 3D viewing media such as spectacles with red/green lenses, 3D televisions with 3D spectacles or video spectacles. A few companies have already introduced 3D televisions that don't require spectacles, but according to experts, this technology is not yet fully developed. Current models only work for one person sitting at a very specific angle to the TV. But in a few years, who knows...
cinemizers by ZEISS are unique 3D spectacles. They simulate a movie screen at a distance of two metres away. This movie screen effect is made possible by small LED monitors inside the spectacles. The frames include headphones for movie sound. A unique feature of these 3D spectacles is that they are also suitable for people who wear spectacles. The prescription strength of an in-built lens can be adjusted from -5 to +2 within the 3D spectacles. Versions are available for the iPod, iPhone, some mobile phones and PlayStation 3 gaming consoles. cinemizers can also be used with your home DVD Blu-ray player.
For those with highly impaired vision, these spectacles can also be worn under the cinemizer as long as it is comfortable for the user.
