Foster Grant’s blue light glasses and readers for women feature a patented lens technology that helps filter blue-violet light* from the sun, as well as artificial sources, including digital devices. Blue light glasses have no magnification while blue light readers have a reader strength in the lens.
Additional women’s blue light reading glasses styles are available at Readers.com® in our family of brands.
*Filters at least 30% of blue-violet light. The percentage refers to the average amount of blue-violet light (between 400-455nm as stated by ISO TR 20772:2018) filtered as measured in 5 nm increments. Covered under U.S. Pat. No. 8,360,574. Other U.S. and foreign patents pending.
