Eyewatch

Imagine you could save your friend Tom from dying of an opioid overdose. Thousands of people lose their loved ones to opioids every year without even realizing the existence of their painkiller habit. What if Tom were next? Luckily, every opioid user (including Tom) has a tell: their pupils get too constricted to appear red in flash photos. Eyewatch uses Google Photos's image recognition to detect opioid users (like Tom) in your pictures and give you advice about you can get them to see a doctor.
