can they be seen by the eye focusing at infinity? —Preceding unsigned comment added by 96.224.69.65 (talk) 02:52, 14 September 2009 (UTC)

  • Highly unlikely. The magnification of the bokode depends on the focal length of the imaging device (in this case the eyeball). Our eye has a focal length of around 17 mm; the distance between the pupil and the optic nerve. Given the 5mm focal length of the lenslet this would result in a magnification of around 3.5x. But if the features of the bokode are but a mere 25 micrometers wide, then even with this magnification it would be incredibly hard to see something smaller than 0.1 mm wide. So, you would be able to see the bokode somewhat, but probably not be able to make out the detail within unless you approached it very closely. -24.202.1.39 (talk) 05:10, 1 October 2009 (UTC)
