    SO Face ID had been working like a charm all day.. last night, I take out my contact lenses (7X power, pretty strong) and Face ID stops working for me? Is that subtle change enough for it to get confused? I put my contacts back in this AM and Face ID is back to normal?

    Anyone else experiencing this?

    No. It isn’t a retinal scanner and it is designed to ignore glasses, etc.

    Maybe your contacts "light up" under infra red? Do you or a friend have a cheap night vision security camera around with infra red illumination? Take a look at yourself with the contacts on with that.

    Try rescanning your face with the contacts out and then put them back. Maybe that will work.

    I switch between contacts and glasses and happened to be wearing glasses yesterday. I took them off to set up Face ID and unlocking has worked with and without wearing them. I’ve yet to put in my contacts.

    Yes exact same experience. Put my contacts back in and it works every time. Take them out and it works maybe 1/5 times.

    Opposite experience. Works for me every time with or without contacts. With glasses (black framed). Even worked this morning in the dark.

    My Face ID didn’t work for me late last night/this morning either. Contacts off/glasses on. My husband says it’s probably my “I just woke up look” that scared the phone.

    Same issue. Contact lenses 8.5X power. Even when I set up without contacts it works with contacts but not when I take them out.

    I wonder if this is relative to a specific brand of contact lenses that may have an unusual coating?

    Can you all please post up your contact lens brand/type?

    I wear Acuvue Vita and the Face ID works well with or with out contacts in. When I wear my glasses, face ID works 9/10 times.

    Update: Just got my brand new glasses and Face ID works with them! :)

    Crap, of course that's my brand and type. My X doesn't arrive for another week so this is concerning.

    There is an option in Face ID settings that doesn't require the phone to check your eyes to unlock. I think it's called 'facial awareness' or something. Can you turn that off and see if it solves your problem?

    I have a feeling it might have to do with the power of our prescription vs the brand of contacts. I’m a over 10x. My husband is a 3x and has no problem.

    Can you try to turn off the "attention awareness" option in Face ID settings and see if that solves the problem? I believe that's a setting that ignores the eyes completely in the process.

    How close were you holding the phone?

    FaceID doesn't work well when it's too close to your face as I found out last night.

    I just tried this, took out my contacts --6.75 power in both eyes - and put on my glasses. And Face ID is working fine. Maybe mine aren’t strong enough? Mine are Alcon Air Optix Day & Night

    That’s a good point. When I take my contacts out at night I’m literally an inch from the phone just because I am blind without them. LOL.

    I turned off require attention for Face ID and it did not work. I tried holding the phone at different distances from my face (2 inches to 36 inches) and nothing worked.

    Huh. Set up with contacts, no issues with or without. Also use glasses and no issues with them either
