Prevention of Blue Light Damage From Mobile Devices

Have you ever seen the visible light spectrum? The colors range from purple, blue, green, indigo, violet, orange, yellow, and red. These are also the colors sunlight is made up of. When they are combined, it becomes the white light we are able to see. Each light on the visible light spectrum has a different energy and wavelength. For instance, rays that are on the red end of the visible spectrum have longer wavelengths and less energy while waves on the blue side have shorter wavelengths and more energy. Keep reading to see how you are exposed to blue light more often than you probably think.


What is blue light?

Blue light is a range of the visible light spectrum that has a wavelength between 400-495 nanometers. The short wavelengths contain higher concentrations of energy than light with longer wavelengths (i.e. white light). Sometimes, the visible light that our eyes can perceive contains blue light rays which, in turn, exposes our eyes to a higher amount of the short, highly-energized wavelengths we previously mentioned. When you stare at a screen for multiple hours, whether it is a cell phone, desktop screen, television, or tablet, you are being exposed to blue light. Blue light exposure from screens can be small in comparison to the amount you’re exposed to from the sun. However, there is concern that long-term exposure can affect your eyes because of the close proximity of the screens and the length of time a person spends looking at them.


How Can I Protect My Eyes from Blue Light?

If you are constantly exposed to blue light from using your smart phones, a tablet, or a computer, there are a few measures you can take to decrease the exposure, those are:

  • The usage of filters. Screen filters are available for smart phones, tablets, and computers. They help decrease the amount of blue light given off from these devices that could potentially harm our eyes.
  • Decrease the amount of time spent looking at the screen or give yourself “screen breaks”.
  • Purchase computer glasses. Computer glasses are made with yellow-tinted lenses and help ease eye strain by increasing the contrast.
  • Use anti-reflective lenses to reduce glare and increase contrast. They also block blue light from the sun and digital devices.
