Chances are, you’re reading this on your phone. If not, then a laptop, tablet, or even desktop computer. What we can guarantee is that you aren’t reading this off of a piece of paper. For better or worse, we live in a highly digitized world, and that means plenty of excess blue light reaching our eyes. Let’s explore why blue light may be a big deal, and one of the ways we can combat its effects — with blue light-protected contact lenses!
What is Blue Light?
Blue light refers to the portion of the visible light spectrum with shorter wavelengths and higher energy levels. It is part of the electromagnetic spectrum and is characterized by its blue color.
Keep in mind that blue light itself isn’t inherently harmful. You can spend a day out in the sun without worrying about your eyes being overwhelmed by blue light. But like all things, moderation is key. And thanks to all of our digital devices, we’re getting more blue light than our eyes have bargained for, and crucially, we’re not receiving it when we expect to.
Blue light plays an essential role in regulating our circadian rhythm, also known as our sleep-wake cycle. Exposure to natural blue light during the day helps to keep us alert, improves mood, and enhances cognitive function.
Blue light exposure can negatively affect our sleep because we are often on our devices late into the night, filling our eyes with blue light, right up until we go to sleep. This often leads to poorer sleep quality.
What Can You Do To Block Blue Light?
Thankfully, there are solutions. While less screen time late at night is strongly recommended, for some of us it is unavoidable. In that case, we offer specially-designed contact lenses with blue light protection.
These lenses are specifically made to filter out blue light, protecting your sleep cycle. If you wear prescription glasses or contact lenses, ask your doctor about blue light-protected contact lenses, to see if they are a good choice for you.
