Review on Protective Blue Light Blocking Glasses: 5 Pack Round Frame Spring Hinge Readers - Stylish Eyewear for Women and Men (1.75x, Assorted Colors) by Rachel Harris

Perfect for the moment. Inexpensive, accurate, light, spring hinges, excellent packaging. They fit my face and don't put too much pressure on my head. What I really liked is that the power of the glasses in diopters was stamped on the frame. The only problem was that I needed glasses to read the rating label. The blue light filter is real. I don't know if blue light filters are important. With the included blue light test kit, I can test other glasses for their ability to filter out blue light. If only for a different reason, this kit is useful in that it includes a tiny flashlight.
