Mother bought a pair of “light therapy” glasses many years ago from a Russian quack site. It was basically a pair of blacked-out safety glasses with ~8 LEDs for each eye and a button cell to power it all. All circuitry and wires fully exposed and visible. You’d set your program and it would cycle through different colors for a predetermined time. Also came with a knock-off Chinese iPod and some gas-station headphones, preloaded with “relaxing sounds from nature.” You were expected to lay there for 30 minutes with your eyes closed as it did its thing. This cost around 600€ in 2019. What an absolute scam.
