If you work an office job, chances are you spend a lot of time staring at your computer screen. Computer screens, office lights and even the sun, project visible and invisible light rays that can have a range of effect on our eyes. However, one light ray that seems to be in the spotlight a lot lately is blue light.
Blue light is on the more powerful end of the light spectrum, so it’s light waves are a lot shorter. You’ve probably heard blue light can be bad for your eyes and overall health. While precautionary measures are recommended, not all exposure to blue light is bad. You may also be wondering if you should be wearing blue light blocking glasses while working on your computer. Keep reading to find out more about blue light and how to keep your eyes protected from harmful light rays.
Blue light can be found almost anywhere. One of the benefits of blue light is that your body uses it to regulate its circadian rhythm.
Your circadian rhythm is your body’s natural sleep and wake cycles. When your body is exposed to blue light, it sends signals to your body to stay awake. Because of this, exposure to blue light can boost your alertness, heighten your reaction times and elevate your mood and overall well-being.
However, this isn’t always a good thing. If you’re watching TV, spending time on your laptop or smartphone before bed, it could hinder the quality of your sleep.
In addition to affecting your natural sleep and wake cycles, blue light can negatively affect your eyesight. Because blue light is among the shortest of light waves, the light waves flicker more easily compared to longer, weaker light waves. This flickering creates a glare that can reduce visual contrast, and affect the sharpness and clarity of your eyesight.
Additionally, it can cause eye strain, blurred vision and headaches. In extreme cases, too much blue light can even lead to permanent eye damage and vision loss.
So, with all this talk of blue light, you may be wondering how you can protect your eyes and body from overexposure to its harmful rays.

They can be worn at work, or before bed to reduce the negative effects of blue light on your eyes and help you sleep better.
