I like the juxtaposition of two of the articles in David Pogue's NYT "Circuits" online column today... The article is about iris scanners, not retina scanners, and it doesn't mention the effects of glasses on it. I'd guess that conventional eyeglasses would interfere with its effectiveness, because they magnify or shrink the image and may distort it in other ways, but perhaps the scanners already need to rescale to adapt to different camera angles and distances. ----------- 6.
