Are Iris Scanning and Face ID Safe For Your Eyes?

[@janelee4484]

Very informative, Dr Ankit. Can you do a similar video on microwave ovens? Some believe that microwave can cause cancer. I'd like to know if research bears this out. Thanks.

[@DocUnlock]

Thank you for the question! Just like infrared, microwaves are also classified as non-ionizing radiation. In fact, the energy of microwaves is lower than infrared and visible light (i.e. microwaves have lower frequency than both visible and infrared light). When absorbed, the main effect of microwaves is that it causes vibration in molecules. This leads to friction and therefore the production of heat - a property that we use to heat up our food! Non-ionizing radiation like microwaves, infrared and visible light, cannot cause cancer. Research also shows that there is no detrimental health issues associated with microwaved food. Also, you may find the following resources helpful if you would like to read further: www.arpansa.gov.au/understanding-radiation/radiation-sources/more-radiation-sources/microwave-ovens www.icnirp.org/en/frequencies/high-frequency/index.html

[@mikerupertus2326]

I am pretty sure that the inside walls of the microwave ovens reflect the waves around so they don't get out, nothing to worry about here

[@DocUnlock]

Yup that's right Mike. Here's a direct quote from the World Health Organization on this point: "The design of microwave ovens ensures that the microwaves are contained within the oven and can only be present when the oven is switched on and the door is shut. Leakage around and through the glass door is limited by design to a level well below that recommended by international standards." www.who.int/peh-emf/publications/facts/info_microwaves/en/

But surely, apple would not have released it if there were concerns that usually go with Laser - burn spots on the retina. 2. I'm a doc too. Love the way you developed a video to explain how cataracts happen with Infra-red. It was amazing. I'd like to do something myself for my patients. Are you able to share how you developed that video.

[@ethnvine]

I used to feel red eyes, headache and dizziness with S9+ Iris scanner. I thought this was due to COVID-19 however, the condition persisted even after several weeks after recovery. So I just guessed this could be due to Iris Scanner and disabled it. The symptoms disappeared after 1.5 days. Splashing cold water on closed eyes also helps. I used to unlock around 50 times per day with about 2 to 4 seconds of exposure everytime, which is not good in the long run.After several years I am sure there will be several reported cases.

[@drcringe7873]

I have a question: shouldnt infrared exposure berättar more dangerous than microwave exposure since infrared has higher frequenscy?

[@amarg1650]

The Problem is that Face ID is ALWAYS ON. You can easily check it with another Phones Camera (because humans cant see it), also when Face ID is turned off and while browsing the Apps the Beam still lits every 5 seconds. This is scary and questionable, also its on when the screen is off ! Apple devices are DEFINATELY DAMAGING THE EYES

Can Face ID infrared be a trigger for people with photosensitive epilepsy, and should they avoid using it?

[@DocUnlock]

Hi Tracey, this is a great question! The disclaimer for Samsung Iris Scan says "Anyone who experiences dizziness, seizures, loss of awareness, blackouts, or other symptoms related to an epileptic condition, should see a doctor before using iris recognition". Photosensitive epilepsy is generally associated with visible light rather than infrared. In an article, red-blue flashes from the Pokeman cartoon were reported to trigger seizure like events in 685 children (www.ncbi.nlm.nih.gov/pubmed?term=16146439). I haven't seen any reports of infrared causing seizures. I think that's because visible light triggers the occipital lobe of the brain (the part that processes vision), but infrared is invisible to us, so it doesn't activate the brain. Having said that, if I had photosensitive epilepsy, I would take the conservative approach and not use Face ID. The convenience just wouldn't be worth the risk of having a seizure (even if that risk is very small)! This is a great question and would be worth asking your Neurologist. He/She will be able to guide you more specifically about your situation. In the meantime, this is a good resource if you are looking for more information about photosensitive epilepsy: www.epilepsy.com/learn/triggers-seizures/photosensitivity-and-seizures

Thank you for your infos, very useful..... My question is: is a camera wich sends infrared emissions to your face and eyes for a twelve hour shift to monitore if your eyes close then sends you vibrations so you don't fall asleep while driving your truck can be harmfull to your eyes ? Would you know wich study to read about the subject (specific to twelve hour exposure) ? Thank you very much for your time !

[@DocUnlock]

Hi Jimi, great question! The health effects of infrared ultimately depends on the amount of exposure to the eye (more formally known as the radiance dose). There are a number of factors that influences radiance dose, and one of them is time. The longer the duration of exposure, the more dose your eye will receive. So if you have an infrared device monitoring your eye for 12 hours, then your eye will receive more dose than if you only wore that device for 10 minutes. However, if the dose of infrared from such a device is still below the international exposure limits, then it should be safe to use. I have two suggestions for you if you want to investigate further: 1) You may wish to read the full guidelines on limits of infrared exposure here: www.icnirp.org/en/frequencies/infrared/index.html The guidelines are quite technical but provide a very comprehensive overview of the health effects of infrared including how radiance dose is calculated and the exposure limits. 2) You may wish to contact the manufacturer of the monitoring device and ask them whether the device has been certified against international standards Hope this helps! Let me know if you have any further questions :)

[@YouGotPropofol]

Amount of exposure: If apple is going to use face-id in ALL its products from here on out, including its iMacs and Macbooks which is coming., then I do believe your will be getting TONS of exposure daily. How many times do you look at your phone per day? It also illuminates while you are using the phone just to check it's you. You are going to use these Apple FaceID products for the next 10 years non stop every day and not worry about the 'amount of exposure'? Anyone that does that is a braver man than me.

[@oohlongjonson]

All over the world trucking companies are installing so-called "Driver Fatigue Monitoring Systems" which uses 850 nanometers wavelength. With IR light source positioned 40cm away from your face, at a rate 8-12 hours a day.. there will be a lot of blind truck drivers in the next few years..

If you do feel something, you can try turning off Face ID and see if that helps. Also, the Animoji feature uses the infrared TrueDepth camera system too. You may want to try turning that off as well.

DocUnlock Thanks for the suggestion, I've tried that before, but it's too complicated to type the code everytime, so I have to turn it on. Plus I'm not sure that's the only reason, the screen is not as great as apple claimed, the color, the night shift is not as natural as some android phone, it's too yellow, and I have to "reduce white point" to relax my eyes, I don't know, maybe it's too "liquid " to me...

[@DocUnlock]

Hi Brendan, in situations like your own, it is always tricky to pin down the exact cause of eye strain. The approach here would be a process of elimination - trying to address each possible cause one by one and see which one makes a difference. You've already turned off Face ID which is a good start. Here are some other things you can do if turning off Face ID doesn't help: 1. Turn off Animoji feature - the Animoji feature also uses the infrared system to detect your face 2. Turn down screen brightness - high brightness may cause your eyes to squint (even without you being conscious of it. This can lead to eye strain. 3. Try using a blue light filter - reducing blue light from screens can reduce eye strain for some people. I think iOS 9.3 onwards has a built in blue light filter called 'Night Shift'. You can try turning this feature on all the time (ie not just for night time use). It would be great if you let us know what happens. It can help other people who may also be experiencing the same problem :)

There are rumours that Samsung flagships in 2019 may not include iris scanning - we'll have to wait and see if this is true. On the other hand, it is predicted that the 2019 iPhone line up will have upgraded Face ID features: 9to5mac.com/2018/11/01/upgraded-face-id-coming-to-2019-iphones-new-ipads-to-arrive-late-next-year-or-early-2020-says-kuo/ Either way, it will be interesting to see what happens :)

So using my iPhone Face ID everyday won’t harm me in the long run?

Recently, infrared temperature devices are being used to supposedly combat the “dangerous🙄” Corona virus spread ( I say supposedly because I think there’s a psychological reason).... Do you think, know or have any opinion on it affecting the pineal gland? Thank you for the great videos!

[@hmhm4861]

Soooo, is it safe or not????

[@flaco.antonio]

Fahd Boufoul It’s safe but soon our future will have Face ID or Body id to unlock every technology in our lives that’s why we should get out more and put our technology off sometimes and I live in modern house so idk what to do 😂
