[Galaxy S8/S8+] Will iris scan work with glasses, sunglasses or contact lens?
When you are wearing glasses with a strong prescription glasses, sunglasses,
color contact lenses, or circular contact lenses, the device may not recognize your irises.
If you are wearing those lenses, remove them before registering your irises.
And, when wearing glasses, the light reflected from glass surface can interfere the sensor,
leading to failure in recognition in some cases. If it is the case, taking glasses off
or adjusting the angle of sight is recommended to get it done.
