It’s coming from your smart phone, your light bulbs, and your LED TV: Toxic. Artificial. Damaging. Blue Light.

Made popular by so-called “biohackers,” blue-blocking glasses have become wildly popular for combating the truly damaging light source.  But is it enough?

In this article I’m discussing exactly why blue-blockers aren’t enough for protecting yourself against toxic lighting at home.

While I do think that blue-blocking glasses can be helpful in protecting yourself from the damaging effects of blue light, I worry that blue blockers lull people into a false sense of assurance that their household lighting and EMF problems are solved.

As humans, our internal clock – or circadian rhythm – is set by morning sunlight exposure and nighttime darkness.  Once set, this internal clock regulates our hormones, metabolism, sleep quality, as well as growth and repair.  Exposure to artificial blue lights after dark signals to your brain that it is solar noon, halting the production of melatonin and drastically reducing sleep quality.

In general, the human system responds [to light cues] in a systematic and predictable manner: light just before habitual bedtime or in the first half of habitual sleep shifts circadian rhythms later (phase delay), while light during the second half of habitual sleep or just after waking shifts circadian rhythms earlier (phase advance).”


I do believe that blue blocking glasses have an important role in a healthy home, but I feel like they are only a partial solution to the problem of toxic blue light.  So in this brief article, I will elaborate on 4 reasons that blue-blocking glasses aren’t enough.


1. Unless you’re wearing blue-blocking goggles, blue light still gets into your eye

As photons of toxic blue light bounce around your home, they are able to bypass the glasses – hitting receptors in your eyes from the top, bottom, and sides of the glasses.  The idea of maximizing ocular coverage is difficult because it must be balanced with high style to gain market acceptance.  I mean, no one wants to wear a pair of amber-colored goggles out on the town.

While some companies, such as Ra Optics (Thutmose is their fullest coverage frame at this time), provide stylish wrap-around styles, no traditional frame will protect your eyes 100%.  Because of this, it becomes even more important to reduce the toxic blue lighting that you are exposed to, especially in your own home.


2. Blue-blockers don’t protect your skin or vital organs from the effects of blue light

Many people don’t know that both the eyes and the skin are capable of sensing light (photoreceptive).  So for the exact same reasons that you want to protect your eyes with blue-blockers, you need to be protecting your skin against circadian-disrupting blue light.

As you read this sentence, I want you to notice where your neck is in relationship to the device you are reading from.  For most of us, sitting at a laptop or looking down over our phones is the perfect angle for blue light hit your neck and important organs just under the skin such as your thyroid gland.  Have you ever considered that thyroid problems could be linked to your exposure to junk lighting?  Blue-blockers can’t protect you from that.


3. You are probably still bathing in dangerous electromagnetic radiation

Do you know what always accompanies toxic blue light?  Man-made radiation, also called non-native electromagnetic frequencies (nnEMF).  So even if you are protecting your eyes from certain wavelengths of blue light, you must also consider the damaging effects of EMF coming from those same devices.

For instance, as long as your “smart” TV is plugged in, it is constantly bombarding everyone in the room with dangerous microwave radiation.   As nighttime is the time for your body to rest and recover, it is also the most important time to minimize the electromagnetic noise that exists in your home.  This, of course, cannot be done with blue-blocking glasses.

4. What about when they are off?

Imagine you wake up in the middle of the night to #1 and the LED street lamp coming through your blinds gives you just enough light to make it to the loo without turning on the lights.  Oops.   You just turned off melatonin production.

Here’s another example: To me, the most inconvenient time to wear blue-blockers is in the shower – where they quickly get soaked and must be removed to wash my face.  So either I can shower with my eyes closed, shower in the dark, or shower normally under CFL bathroom lights and turn off melatonin production.

The point is, there are times in the evening that your glasses will be off.  And unless you have addressed the toxic lighting situation in your home, blue-blockers can’t protect you.


5. Blue-blockers don’t address blue light addiction

Flickering blue light releases dopamine in the brain, creating a chemical response and activating the addiction pathways.  That’s right.  I’m suggesting that the only reason you’ve even read this far is because you are addicted to blue light.

I know it may not be what you want to hear, but perhaps the reason why you want so badly for glasses to “give you permission” to binge on Westworld all night long is because you are addicted to screens.


How to Protect Yourself from Blue Light Toxicity

  • Ideally, limit your screen use to daylight hours, taking it farther by balancing the harsh blues with red incandescent bulbs in front of you while on screens
  • Create a home and sleep environment that is free from all artificial light (this may require black-out curtains and LED indicator light covers)
  • In the evening, light your home with a nontoxic 100% beeswax candle, the best choice for indoor air quality concerns
  • If you must be exposed to blue light in the evening, wear blue-blocking glasses (I recommend Ra Optics) and keep as much of your skin covered as possible
  • Reduce nnEMF in the home by eliminating Bluetooth, wireless, and “smart” devices and unplugging electronics when not in use
  • Use screen filtering software such as Iris , CF.lumen, or f.lux
