Not for the sake of anti-blue light

Prolonged viewing of electronic screens can lead to Computer Vision Syndrome (CVS)

Electronic screens produce electromagnetic waves from 380 nanometers (ultraviolet) to 750 nanometers of visible light.
Screens also emit a small amount of blue light with wavelengths between about 440 nanometers and 500 nanometers. This blue light wavelength can cause eye strain and visual discomfort during the use of electronic devices. As a result, some screen protection technologies, such as blue light filters or rare earth coatings, are designed to mitigate this potential discomfort.
Of course Computer Vision Syndrome (CVS) is primarily caused by prolonged viewing of electronic screens

The solutions are:

  1. Follow the 20-20-20 Rule: Take a 20-second break to look at something 20 feet away every 20 minutes of screen time.
  2. Proper Lighting: Ensure appropriate lighting in the environment to reduce glare and eyestrain.
  3. Ergonomic Setup: Maintain a comfortable viewing distance and angle, and use ergonomic furniture.
  4. Blue Light Filters: Consider using blue light filters or screen protectors to reduce exposure.
  5. Regular Eye Exams: Regular eye examinations can detect and address vision issues.

So refracting away blue light is the reason why you need to use electronic devices for long periods of time and forget to take breaks to reduce some of the digital strain on your eyes.
We use rare earths to coat cell phone screen protectors, which not only don't distort the color of the screen, but also have improved the quality and reduce the discomfort of digital fatigue.
