Infrared Goggles an Urban Armoury Series

The objective of Infrared goggles is to protect privacy of a private citizen in this social media frenzied world where one could be accidentally included in the massive occurrence of picture and video taking in public places and then sharing on social media.

True, one could argue that why not wear a sunglasses or oversized sunnies? The matter of discussion here is for the private citizen to remain connected and socially included in the community, maintaining eye contact with another human being during a conversation while being shielded from preying lenses. On the contrary, sunglasses abstracted such functions and hence the less emphatic approach. The crux of this i'ble is based on the concept of human eyes are incapable of perceiving infrared light at the spectrum of 700nm to 1000nm, while modern lenses and picture taking devices are able to captured it. More details here https://www.eyespypro.com/pages/Understanding-IR-Illuminiation.html While wearing this Infrared Goggles, the humans engaged in the conversation will be oblivious to the urban armour, but image acquisition devices will perceived light. It is very simple to construct Infrared Googles. One would need some Infrared LED strip, a clear type eye protection PPE, some hot glue, and adequate power supply. In this i'ble, an 850nm Infrared LED strip is used with a 59mm clear type eye protection PPE. power supply is LiFePO4 battery pack that supplies 12V with a capacity of 2800mAH.
