Portable Blue Light Glasses
Just like their more standard-sized counterparts, Foster Grant® To-Go Blue Light Glasses help filter blue-violet light* from the sun, as well as artificial sources, including digital devices. But they do so with a design that allows them to fold up flat for discreet and ultra-compact carrying when you’re on-the-go.
*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.
