2023-05-07 (Su) Privacy Glasses COMPLETED

Years ago, I saw someone wearing Reflectacles, and the idea struck me as brilliant. I was concerned with the overuse of facial recognition, and I always thought it was worth implementing, but I didn't wear glasses, so it never seemed practical. Now that I have eyewear for long-distance help, I decided to build myself a pair.

I ordered a pair of chunky red glasses and 3M retroreflective tape. I remembered how well the tape performed in my RemoteFinishLine project. My tools were some non-stick scissors and a scalpel.
Materials

First, I removed the lenses, then applied a band of tape across the top of the glasses. I trimmed away the excess because I would not let it reduce my vision field. The best method was to make relief cuts with the scissors and then trim away the flaps with the scalpel. I followed the frames as closely as possible.
Lenses out, tape on

I added small strips of reflective tape to the frames at the sides and bottom because a strip across the top was not enough to obscure my face from an IR camera. I didn't put tape anywhere it could touch my skin because the sharp edges would irritate me in a hurry.
Ragged edges but effective reflectors

I took several test images, but the first one showed that the forehead band was probably not enough to fool a camera. I was pleased with how well the band reflected the IR emissions.
Not enough coverage

After I added the side and bottom strips to my glasses, I retested them. The best evidence was that the background appeared darker than the first picture because the camera required a faster shutter speed to keep from oversaturating the image with all the reflected light. Success!
Highly effective head-on

Angled pictures showed that the tape was still effective, and hopefully, the position would render a camera unable to identify me.
Excellent reflection at a steep angle

The best shots were when I held the camera further than arm's length. I was delighted that so much was obscured by the tape, and it's a passive countermeasure, so I don't need to maintain batteries or sensors.
Who's that?
