We're exposed to blue light everywhere from digital screens, artificial light, as well as sunlight and UV rays, which can harm your eyes and make them feel tired, dry, or irritated. With Zenni Blokz, you can prevent these negative symptoms and block both UV and high energy visible blue light to ensure a better night sleep.
The blue light laser pen featured in this video emits 405 ± 10 nm blue light to help illustrate the blue-light-blocking qualities of Blokz.
