It was an extreme close-up of:

The Bright Basics Clip-On LED Glasses Light! Clip them on any pair of glasses and wherever you look, you have light. They’re from Audro Products (I’ve bought a lot of their stuff over the years) and two of them is about $15.00. I didn’t see them on Amazon when I looked on May 1st, but they are on the company website
