Subject: Stop digital cameras from taking photos?

Interesting article on C|NET:
http://news.com.com/Crave+privacy+New+tech+knocks+out+digital+cameras/2100-7337_3-5869832.html?tag=nefd.lede

Reading about the way this putative technology works is to wonder how anyone 
wearing spectacles is going to be able to cope.  IIR(ead)C, the response is 
generated because of a reflection from a lens.  Therefore all lenses will 
extract a response.  Spectacles, all cameras, etc.  Why pick on digital?  Apart 
from for fun, of course.


Answering myself, it's because digital lenses have some "coating" that puts them "in 
a class of their own".  So that's all cobblers, then.

My glasses have a coating too -- looks a lot like the ones on my camera lenses.
