For people wondering about eye-ball tracking on an ad-focused implementation of this, I’m curious how long it’ll be till glasses wearers can get a coating to block it. My glasses already come with coatings for various other things (UV, anti-reflective, scratch resistance, anti-fog, blue-blocking, mirroring, etc) Some already cause issues with eye-scanning. Eg FaceID on iOS doesn’t always work with polarizing lenses. I’d love an extra privacy-focused “screw up facial recognition/eye scanning tech” option.
