Blue light is all around you as well as other colored visible light. The sun is glowing blue. The same goes for fluorescent and incandescent lamps. Humans are exposed to more blue light than ever before because devices that rely on light-emitting diode (LED) technology are becoming more popular. Your computer screens, laptop, iPad, TVs, mobile phones, and tablets all use LED technology, which carries large amounts of blue light.
*Disclaimer: Harmful blue-violet light is between 415-455nm.

While high-quality blue light blocking glasses can reduce the exposure of your eyes here are a few more ways by which you can limit your exposure to the harmful rays emitted by digital devices.
When you are using your phone or computer screen, take a break after every 20 minutes and look at an object placed 20 feet away for 20 seconds.
Eye drops like artificial tears and an indoor humidifier is good ways to prevent your eyes from becoming too dry and irritated while using the blue light-emitting device.
Long-term squinting of the screen is not recommended for overall eye health. If you wear eyeglasses for vision correction, make sure you are wearing prescription eyeglasses for the distance between your eyes and the screen (ideally arm length). Most of the glass is contained for long-distance use.
It is recommended to set the screen to a warm tone “overnight” setting to reduce the risk of eye strain and sleep disturbance. You can purchase a blue light filtering screen to bypass your computer's screen while you work at night. Filters can block glare on the screen. Also, source shows that it blocks 30-60% of blue light, but it's unclear whether it can block blue light and help maintain the sleep-wake cycle in people who use backlit screens before bedtime.
