YES. Please click here to see our AVN testing document from an independent lab. AVN stands for "anti visual noise" - that is what most eye care professionals call blue light glasses. This testing document shows the percentage of blue light that penetrated ("transmitted") through the lens in testing depending on the wavelength. The most harmful wavelengths of light are below 420nm which our lenses blocked over 80%. Let us know if you would like clarification on how to read the chart.
