WTF, X-ray.. sunglasses?

[PokieMon]

Out with friends over lunch the other day, and I realized that one of the girls, who was in the direct sun, had a black blouse on that was very slightly sheer. After a while, I realized that I could just barely see though it and see what she was wearing underneath. Nothing terribly erotic, just a spaghetti strap camisole, but I still find that kind of peak under the covers so to speak incredibly hot (more so when its intentional, which this wasn't, but still..). When a shadow covered her for a minute, the blouse was opaque. Then here's where things took a turn for the weird, I took off my sunglasses for a bit, and poof, the blouse was opaque black, even though she was still in the sun. Put them on, slightly sheer, sunglasses off, opaque as can be. By now I'm thinking WTF, X-ray sunglasses? Completely destroyed my concentration for the rest of the afternoon.

Has anyone else ever had any kind of similar experience?


Actually, sounds like an interesting premise for a story.. maybe I'll write one around it someday.

Not X-rays (no ionizing radiation), not magic, merely polarization and a bit of optical filtering, or lack thereof. Most sunglasses and digital cameras are built to filter-out infrared (IR) light. tweak the filtering, polarize the passed light, and you get exactly the effect you reported.

I've used infrared-pass filters on digital cameras in daylight to penetrate many thin fabrics, especially sheer black. Some Sony camcorders and superzooms infamously had such natural-light IR-pass filtering. My little old DSC-V20 has a crippled version of that (which I defeated, heh heh).

A guy replaces his sunglass lenses with gel IR filters. Or he puts a glass IR filter on his dSLR's fast telephoto lens. He heads out to see more than human eyes normally notice.
