The Role of Blue Light
You may have heard the term “blue light” used before, especially when shopping for new glasses, but what is it, and what does it actually do to your eyes?
Blue light is a specific wavelength of visible light we’re exposed to every single day. We get most of our blue light from the sun, and our brain interprets this light as a sign to be awake, alert, and active. Smaller amounts of blue light are also emitted from our screens. However, overexposure to blue light can cause symptoms that could affect our vision and overall health.
Studies have shown that too much blue light exposure before bed can disrupt our circadian rhythm, affecting our ability to sleep.
We recommend wearing blue light protection when working with digital devices for long periods and sunglasses when you are outside on sunny days. If you’re having trouble sleeping, try limiting your device use before going to bed.
