Are glasses that detect and flash for cigarette smoke feasible?

Question

I’ve been thinking about a wearable that could make cigarette smoke more visible in public settings. Imagine glasses that flash lights whenever they detect cigarette smoke. The goal isn’t for the wearer to detect cigarette smoke—they can already smell it—but to alert others that there’s secondhand smoke in the area and show smokers how far their smoke travels, making the invisible visible.

The concept of glasses that flash lights when detecting cigarette smoke is an innovative approach to raising awareness about secondhand smoke. To make this idea feasible, the glasses would need to be equipped with a reliable smoke detection sensor, likely using a gas sensor that can identify the chemicals present in cigarette smoke. The device would also need to be calibrated to avoid false positives from other sources of smoke or particles. Additionally, the visual alert system should be designed to be noticeable but not distracting or obtrusive.
