So what do you folks think about iris scanners on phones? Safe or not?

[J Dubbs]

So would you guys and gals be comfortable having your eyes scanned multiple times a day for the rest of your life to unlock your phone? Would you be worried about possible eye issues like cancers/cataracts etc down the road?

It's basically an IR camera... nothing to worry about.

It's not really "scanning" anything; it's basically a camera coupled with a weak IR sensor that tries to figure out when there is a face in front of the phone. From a health perspective, it's probably much safer than the eye tracking sensors also used in phones. Which is to say, approximately 0% of people will have negative impacts from that and those that would, are merely compounding the impacts of looking at the screen that much. Looking at the screen all day is WAY worse for your eyes than anything this camera will do.

Not concerned. Used it on the Lumia 950 and it's kind of cool, if not fickle too.

I set up the Iris Scanner on my new Note 7 today and I was surprised by how FAST it was, but I thought to myself "It is no faster than the fingerprint scanner". So I just turned it off.
