This is just a 1% solution, which may be enough to defeat mass data collection as long as it remains niche. For a bigger effect, carry light strong enough to saturate even a HDR camera.

If you remember the old (VHS) Macrovision, it used a pulsing contrast to mess up automatic gain control circuits. A good way to defeat this is by putting a POT on the AGC so you can tune it manually.
A way to apply this to the glasses: put a IR strobe on. Pulse it at .5s, with a .05s IR led on time.
You should be able to get away with this using an array of IRleds, battery, and a 555 timer.
