A secret agent needs to be descreet at all times. These night vision contact lenses look just like ordinary lenses but have a special luminent coating reactant to light which makes your surroundings look much clearer. The fact that you arnt carrying a huge pair of goggles dosent advertise the fact your working for the enemy. You could also try to make a pair of thermal imaging lenses.-- BIG BAD PETE, Sep 17 2001 "Special luminent coating?" Blah. Magic.-- jutta, Sep 17 2001 I suppose it could be feasible that the lenses act like those reactive glasses lenses - but by blocking out all light other than infra red - however since we don't see in that spectrum anyway they would just make the spy blind.-- fridge duck, Jan 19 2005 What do you mean "special spy equipment", I'm just playing face ludo.-- wagster, Jan 19 2005 // however since we don't see in that spectrum anyway they would just make the spy blind.//
Unless..... The electronic equipment usually utilised in the goggles to do all the technical jiggery pokery is minituarised and installed into the users head - they could then receive a signal from the contact lense, convert it and pump it straight into the brain...-- RichieRich, Jan 19 2005 random, halfbakery
