Safety warning (sorry)

[klishnor.livejournal.com]

Please, whatever you do, don't wear them whilst driving. They may darken in five seconds or so, but they can take twenty minutes to return to clear at room temperature (information obtained from some very small print at the bottom of an advert for the British version)

Imagine the effect of driving along a brightly sunlit road and entering a tunnel or underground carpark.

When the first version of these (under the tradename Reactolite) went on sale, the road safety types went crazy about this as the adverts showed them being used by drivers.
