Blue Light Lens Technology

What is blue light?

Blue light is light that is between 400 and 500 nanometres (nm) in wavelength. We find it everywhere around us, produced naturally and artificially. It's emitted by the sun, but also by street lights, our smartphones, and laptops. Ultimately, in moderation, like other forms of light, it's fine. However, recent studies have shown that blue light is more likely than light at higher wavelengths to cause eyestrain. In the day time and in moderation, this may not be problematic. As the day turns into the night, this becomes a problem though, both for our eyes and for our sleep quality.

What can you do?

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