BlueCruise, Glasses, and Nightime.

So now that it’s getting dark earlier I have learned that I can’t get the nanny cam to stop kicking BC off. Yes, I have a high prescription, I even have prisms.

During the day I can wear my shades and use BC all day, but at night as soon as the sun goes down every couple second….watch the road. I thought maybe polarized lenses were what helped, but the yellow tinted glasses don’t seem to help. If I get wearing gray tinted shades at night it’s fine…except then I am wearing dark tinted glasses at night.

Anyone else have a similar problem and been able to overcome it? Or is just this another category of how screwed up my vision is.

Sadly makes BC 100% unusable once the sun goes down.

Without tilting your head, can you see the bar behind the steering wheel where the camera is? On one of my pairs of glasses the frames can block that bar which triggers the nag.

Yeah I can see the bar pretty easily. And if I put shades over the glasses…no nag (well at least a reasonable workable amount of nag).

Have tried adjust the seat/wheel all over the place. My guess would be reflections of lights come into the lenses and prisms cause that light (and potentially the IR from the camera) to scatter everywhere. My theory is polarization cuts the amount of light coming in enough for the camera to detect my eyeballs…cutting light it great in the day, not the best idea at night sadly.

Do you have an anti-reflective coating on your glasses? The combination of prisms, reflections, and strong prescription may confuse the camera.

Yeah AR coating on the lens.

Yeah AR coating on the lens.

I suspect that is the issue. The eye camera use IR which is probably reflected by your lenses.

hmm driving without an AR coating would kinda suck. Guess I could at least wear the yellow tint polarized lenses.

I was wondering what would happen if you put a polarized sheet on the nanny camera itself but I suppose that wouldn’t help the IR beam correctly.

Take a picture of your face with the flash turned on from the same angle as the nanny cam, and I think you'll see the problem.

You might need to get a pair of driving glasses that does not have as strong of a reading prescription. Lenses should be single vision or a minimal varifocal to minimize reflections inside the lens.

Sadly I have the same issues with single vision. Prisms might be the bigger issue, or the strabismus.

It would be interesting to know if you have the same problem using facial recognition on your phone. I would think the same problem would prevent you from unlocking your phone. At least for iOS you have to be looking at the phone to unlock it. If it can’t see your eyes it won’t unlock. Sorry just curious no solution for the BC.

Generally not a problem on iPhone, but I assume that is using a RGB camera. I have no issues seeing my eyes on say my phones front facing camera.

iPhone uses True Depth camera IR camera. It projects thousands of IR dots on your face and takes an IR image of those dots then compares it to the logged map. Not sure how the car camera works but maybe they should look into this tech.

You can setup the iPhone to not be as sensitive to the eye area - alternate appearance, don't require attention for Face ID, etc. Nothing you can really do with BC as it strictly checks your eyes.

I’ve had similar problems since day 1. One thing I’ve found that helps is to slightly tilt my glasses down (so that the ear pieces are slightly above my ears). It’s obviously awkward and dorky but it seems to help with the nanny cam.

One theory I had was this may change the angle of the light being reflected back off of the screens on my glasses which may have been confusing the camera.

Could be. Another thing I should mention is there might be a software update for the eye tracker that improves performance in difficult scenarios such as yours. If you send your VIN to me or the guys in the update check topic, they can let you know if you have a CMR update available, which could help.
