Keep your eyes fresh while looking stylish in the Jasper Blue Light Reader. This fully magnified reader has patented lens technology that helps filter blue-violet light.*

This style has an anti-reflective lens technology to improve clarity. 

The lenses are scratch and impact-resistant.

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.
