Welcome to the modern world, where we stare at tiny suns (aka screens) all day, tell ourselves it’s “productivity,” and then wonder why we’re exhausted, anxious, and inflamed.
Most people know screens are bad for their eyes — but very few understand the mechanism, and it starts with what blue light is and how it interacts with the cells responsible for your body's energy production.
Back in 2016, some “experts” were claiming artificial blue light was basically harmless. Dr. Jack Kruse, neurosurgeon and full-time light whisperer, called B.S. And now, the research has caught up.
According to Dr. Kruse in HYPOXIA #15, the blue light blasting from your phone, tablet, and overhead LEDs isn’t just annoying—it causes irreversible hypoxia in all your cells.
The visible symptoms — eye strain, headaches, poor sleep — are covered in our post on Computer Vision Syndrome, but the cellular damage described in this article is the root cause.
That’s right. Your mitochondria (those tiny energy factories you keep hearing about) are being suffocated. But hey, at least you look great in that ring light.
Readers who want the full protective picture — including which wavelengths are most dangerous and how to block them — should read our complete guide to blue and green light blocking glasses.
In a 2018 study Kruse cites, artificial blue light was shown to cause serious retinal damage. That’s not a tinfoil hat opinion—that’s peer-reviewed reality. And the effects aren’t limited to your eyes. Once you trash your retina’s ability to signal time and light correctly, your entire hormonal system starts glitching like a broken iPhone.
“The retina is the most powerful circadian signaling device humans possess, and blue light destroys it.”
— Dr. Jack Kruse, HYPOXIA #15
Just think of blue light like sugar for your eyeballs—except instead of a cavity, you get mitochondrial failure and brain fog.
The headaches many screen users experience daily are a direct manifestation of mitochondrial stress — our post on whether blue light glasses help with headaches connects this science to the symptom.
Green light operates by the same harmful mechanism — our guide to green light blocking glasses explains the full-spectrum threat most people are still unaware of.
Children's mitochondria are more susceptible to oxidative stress from light exposure — our guide to blue light glasses for kids explains what parents can do about it right now.
Dr. Kruse doesn’t mince words:
“The wrong light at the wrong time = chronic disease.”

Blue light exposure—especially after sunset—suppresses melatonin, disrupts dopamine, messes with leptin, and flips your circadian rhythm upside down. And if you’re wondering why your mood is trash, your sleep sucks, and your energy tank is always on empty... look no further than the glowing rectangle in your hand.
Because giving up electricity entirely might be a bit extreme.
Block 100% of artificial blue light after sunset so your brain can finally get the memo: it’s bedtime. Not casino o’clock.
First light of day should hit your eyes from the sun, not your Instagram feed. Natural blue light in the morning = serotonin and cortisol production. Artificial blue light at night = depression and belly fat.
Red light doesn’t confuse your circadian rhythm. It soothes it. Pro tip: replace every LED in your bedroom and bathroom with red or amber bulbs.
“We don’t need more food gurus. We need light gurus.”
