Scanning laser ophthalmoscopy

[anhinga_anhinga]

Now the eye exam can be made without eye drops which dilate the pupils, so one can read or drive afterwards. Another good thing is that the resulting pictures are stored, so it is possible to track the changes over the years.

And the pictures are pretty cool and resemble some of pictures obtained from space telescopes, which is not so surprising, since the same methods of adaptive optics are used:

There still were couple of downsides. My vision care insurance would pay for the dilation, but would not cover these photos, so it was $39. And I did not get the e-mail with those photos (at least, not yet).

easy to abuse them?

Many commercially available iris recognition systems are easily fooled by presenting a high-quality photograph of a face instead of a real face, which makes such devices unsuitable for unsupervised applications, such as door access-control systems.

Retinal scan is much harder to fake, if I recall.
