Blue light blocking lenses
What’s wrong with blue light?
White light is made up all the other colours from Red to Blue. Blue light, however, packs more of a punch in terms of energy, and this can pose a problem in two ways:
- It can cause dry, strained, and fatigued eyes, even leading to headaches.
- The blue light signals your brain that it’s still daytime. This pushes back your sleep cycle making you feel tired and unrested in the morning.
But isn’t blue light natural? Why is it a problem all of a sudden?
Technology. Technology and bad habits.
We are increasingly attached to our digital devices–both for leisure and for work. This high-energy blue light from our phones, computers and tablets is more than our eyes are accustomed to. We are also using these devices closer to our bedtime.
By using a coating that filters out some of the high-energy blue light, you reduce the cumulative effects and return your blue absorption to normal levels.
- Avoid using digital devices at least 1 hour before bedtime.
- The 20/20/20 Rule: When using your phone, tablet or computer, every 20 minutes look 20 feet away for 20 seconds. This relaxes your eyes and reminds you to blink. (We blink 60% less when looking at screens!)
- Consider installing f.lux on your computer–a lightweight program that gradually shifts your computer screen to redder tones as the day progresses. Your computer mimics what happens in the natural sky (ie. less blue light closer to bed… which is what your eyes expect).
