Can I use the iris scanner to unlock my Samsung Galaxy device if I wear glasses?

Will the iris scanner work when I am wearing glasses or contact lenses?

The device may not recognise your irises if you are wearing glasses, sunglasses or contact lenses. The light reflected on the glass may interfere with the sensor leading to the device to not recognise your iris.

You will need to remove any glasses or contact lenses before registering your irises.


I'm going to have laser surgery. Will the iris scanner still recognise my irises?

If you have undergone laser-assisted vision surgery, the refraction of light to your eyes will change because of a change in your cornea. You will need to re-register your irises on the device before using the iris scanner.


What if I have conjunctivitis or a similar medical condition relating to my eyes? Will the scanner still work?

Eye diseases should not disrupt the scanner unless your eyes are severely swollen.
