What is blue light?

Blue light refers to visible light between 400 and 500 nanometers (nm) in wavelength. We find it everywhere around us, produced both naturally and artificially. It's emitted by the sun, but also by street lights, our smartphones, and laptops. In the day time and in moderation, blue light is fine. As the day turns into the night, it becomes problematic, however, as we are overexposed to it (relative to how humans adapted over thousands of years). Recent studies show that blue light can thus cause eyestrain and disrupt our sleep quality.

The Night Owl Advantage  

Night Owl Glasses offer a solution to this problem, providing a protective lens that blocks out blue light and prevents it from reaching your eyes in large quantities. Our glasses reduce the intensity of blue light, helping you to improve your sleep quality and reduce eyestrain.
