3D

[naushaad]

Could someone please tell me why we need special expensive glasses to watch 3D movies on plasmas and LEd's at home but the more simple glasses when at the cinema? Just wondering.

Thanks

It's much easier and cheaper for manufacturers to use active shutter glasses as that way they only need to adapt their current panels rather than design new panels capable of retaining the polarisation of the light. I believe LG is planning to releasing panels that work with passive glasses though.

They are welcome to develop a tv that works with passive glasses.
Will I now jump at 3D.
No...

In the cinema special projectors are used that polarises (circular polarisation) the images for each eye. That's why passive filter glasses are used in the cinema. Currently no commercial (for home use) display devices support the polarisation of light. Hence the need for active shutters to block the image to each eye in synch with the screen.

Also, 3D is bad for you... youngsters especially with the development or vision.

TV is bad for youngsters, period.

3D is bad for them physically. Up to the age of about 11, your eyes learn to adjust focus and alignment in step with each other, so that you see a single image (collimated) and a focused one. It becomes hard-wired in your brain. When you watch 3d, the eye does not adjust its focus and alignment in step, and it really badly affects the hard-wired ability to learn this. THe remedial eye exercises that many kids do as part of OT are designed to correct a lack of this ability. The main symptom is an inability to read - the eye can't track the lines on a page and stay focused at the same time. Beyond 11 it's not correctable.

So anyone with kids under 12 - PLEASE stay away from 3D television. The odd 3D movie won't hurt them. (Source: New Scientist)

If you give people the information on a page on ave, they retain 85%, make a movie with the info, they retain 35% of the info, put it on a screen, they retain 3% of it....

flickering /bright light is a warning signal to our Limbic system (primitive brain), The limbic system overrides the frontal brain (it shuts off), and once in a while there is a flashy thing usually in an ad... they are made that way to trigger an assessment... and then the limbic system causes the heart rate to increase  and release cortisol a stress hormone, as this happens the frontal lobes wake up to assess the situation, and tell the limbic brain, there's no danger. So whatever happens there is no danger. Also because the Frontal lobe is "switched off" so much more frequently than without TV, the development required by the brain does not happen.
