I see that those are only "Passive" glasses, I would want "Active/Shutter" glasses which would no doubt cost significantly more.Hmm - £80 from here: http://www.uksportseyewear.co.uk/product.php/200/3d-prescription-glasses-passive-polarized-polarised
I think I'll give that miss for now, and stick with the double glazing.

I think that I will pass on 3D for the time being.
3D TV is currently not very user friendly for prescription glasses wearers, there doesn't seem to be much mention made of prescription 3D glasses being available, let alone what they would cost.
I too used to be a PO Engineer, but never worked on telex or data stuff. I do remember early facsimile machines, where the sender wrapped an A4 sheet on a drum and the receiver had some paper which I think was electro sensitive and was scratched by a stylus. They were on the ends of ICI and BP private circuits which way back in the sixties cost or tens of thousands of pounds per year to rent. Something which now can be done for a few quid a month via the WWW.Used to work with post office CCITT V21 300 baud Full duplex and CCITT V23 1200 / 75 Baud half duplex modems, Happy days ! !
