The Duncan Blue Light Reader
The Duncan Blue Light Reader is a sleek, minimalistic full-frame square style that has patented lens technology that helps filter blue-violet light.*
This reader also has an anti-reflective lens technology to improve clarity.
Sunlight is the main source of blue light, and not just outside, but windows let blue light through, too. Artificial sources, including household lights and digital screens, are also sources of blue light.
