Portable Blue Light Glasses
Now you can filter blue-violet light from the sun and digital devices wherever you go with our range of portable blue light glasses. Just like their more standard-sized counterparts, Foster Grant® To-Go Blue Light Glasses help to filter up to 30% of blue-violet light.* But they do so with designs that allow them to fold up flat for discreet and ultra-compact carrying when you’re on-the-go.
*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.
