If you’re someone who stares at a computer screen for 8+ hours a day, you’re probably familiar with that frazzled feeling your eyes get after you shut it down for the day. Your pupils are strained, your retinas hurt and you might even be seeing spots when you close your eyes!
You might think closing your eyes and rubbing your temples is all you can do in the way of eye care in Cape Cod, but what you might not realize is that the problem runs deeper than just a long day at work.
This feeling is becoming more and more prominent in today’s technologically-driven world and it’s called “digital eye strain.” Digital eye strain can be caused by looking at any electronic device screen: be it a computer, television, tablet or even a smartphone. And, more importantly, what’s causing digital eye strain is something called “blue light.”
What makes blue light so special, as opposed to any other color in the spectrum of light? Simple: blue has the shortest wavelength—meaning it produces a much higher amount of energy. Moreover, blue light is right next to ultraviolet light on the spectrum of light! Throughout the day, while we’re staring at a screen, the energy that blue light produces is bombarding our eyes, slowly wearing them down until they hurt!
Blue light is particularly detrimental because of how it affects our eyes. Blue light penetrates deep into our eyes to directly affect the back of your eye, where light is processed into electrical impulses that are translated by our brain. In particular, blue light wrecks havoc on our choroids, retinas, fovea and, most importantly, our optic nerves. This is why we often get headaches and tension behind our eyes: because the parts of our eyes that process light are being fried by high concentrations of blue light!
At this point you’re probably asking yourself, “what can I do to prevent eye damage from blue light?” It’s not like you can stop using a computer at your job or ask someone to print off all the pictures on their phone for you to look at! Don’t worry: there are ways to reduce blue light damage without removing electronic screens from your life. To combat blue light, you’re going to need to take into account preventative eye care in Cape Cod:
- Give your eyes a break every hour or so. It’s recommended that you get up and move around for five minutes every 45 minutes of sitting anyway, so giving your eyes a rest is also a good idea throughout the day.
- If you work third shift or find yourself in a dark room looking at a bright screen, invest in a pair of computer glasses. These glasses actually work to filter out blue light, protecting your eyes from blue light waves.
- There are a variety of computer programs out there designed to help filter blue light by substituting warmer light, such as orange. Installing these and setting them to run at appropriate times of the day (sundown and evening) can mitigate the amount of blue light you’re exposed to.
If you continue to find that your eyes are strained and you’re suffering from frequent headaches and tension due to digital eye strain, consult with your eye doctor about what you can do to help alleviate the effects of blue light in your life!
