Men's Blue Light Glasses and Readers
Foster Grant’s blue light glasses and reading glasses feature a patented lens technology that helps filter at least 30% of blue-violet light* from the sun and digital devices. Choose from blue light glasses with no magnification or blue light readers that have a reader strength in the lens.
*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.
