The real question is do they really work, and if so how? I'm not aware of any technology that is capable of converting infra-red to visible light except with a significant input of power, which is obviously not available in the case of contact lenses.
Ive said "I discovered at an early age that all I've ever wanted to do is design" and even for Apple haters his designs have done more for personal computer design than the mainstream PC manufacturers could imagine, taking the PC from the geek den into the living room of even the most painfully trendy fashionista."

Hopefully gas station pumps can continue to ask for a ZIP rather than a PIN. Just a personal preference.
That is really annoying for those who don' t live in the USA so have no zip code. It means two extra trips to the booth to get your credit card read and approved, and then debited with the actual amount of gas used. Almost all other countries use a PIN number (typically 4 digits) to approve credit card purchases done by machine but machines in the USA don't seem to be able to read them. I can't wait for the USA to catch up with the rest of the world.
But I suppose one can't expect any more of the only part of the world not to use International Standard road signs, A4 paper, 00 as the international dialling prefix, 230/240 volt mains, and metric units.
