This isn't about emotions and it's not about how you feel. Scientifically speaking: you're sensitive.
The cells and tissue that form your physical body are altered by the modern world all around us. We already accept this as factual when it comes to the foods we eat and the air we breathe but what about the effects of exposure radiation, consistent light pollution, and high energy blue light? Culturally and socially we're obsessed with screens. But as with all obsessions, there's an underbelly of side effects: our beloved tech is almost certainly having an impact on our overall health.
Part 1. Not To Be Dramatic, But Your Tech Is Aging You.
Light emissions from tech devices like your smartphone, laptop, and tablet are harming us in more ways than one. The easiest way to make sense of this information is to understand the way devices (like the one you're reading this on right now) produces a type of "polution" that directly impacts our bodies natural rhythms and optimal functions. Blue Light is powerful and penetrates through your cornea, past your lenses, and into your retina with the ability to cause dysfunction within each layer of your eyeball.
Part 2. Blue Light Is The Only B*tch In The Room
What's the official definition of Blue light? Here's the Wikipedia definition since we know you're going to Google anyways:
Blue light or high energy visible (HEV) light, is a range of the visible light spectrum, defined as having a wavelength between 400−495 nm. This short wavelength means that blue light is a type of high-energy visible light, defined as having a wavelength between 400 and 450 nm. FYI: high-energy visible light (HEV light) is high-frequency, high-energy light in the violet/blue band from 400 to 450 nm in the visible spectrum.
The cornea is positioned at the front end of the eyeball and is the first "filter" that light passes through when being processed by your eyeballs. Ocular inflammation is the technical term given to that feeling of dry eyes or frantically blinking while trying to read a label or something that's not digitized. Some more not great news: like the rays from the sun, Blue Light may increase the development of cataracts which is altogether unsexy to talk about —and all the more reason to never take your sunglasses off (even at night).
Part 3. Preventing Cellular Damage Is The Most Effective Way To Slow Down Aging
We're super protective of our dermis bc that's where collagen and elastin are created. Just like UVA and UVB rays, Blue Light is also associated with premature aging. A study published in the Journal of Investigative Dermatology found that exposure to blue light resulted in more redness, swelling and pigment production than UVA. And these changes lasted up to two weeks from a single blue light exposure, compared to the damage done by the UVA that faded within a few days. While blue light has not been shown to cause skin cancers, it does lead to overproduction of pigmentation which causes hyperpigmentation. Blue Light can penetrate deeper into the skin all the way to our dermis.
Part 4. Unfiltered Tech Is Gross
To preserve your visual abilities aka maintaining the ability to see things it's advisable to filter as much Blue Light as possible before it reaches your cornea. Blue light has been shown to increase reactive oxygen production in corneal. Blue light irradiation also has been shown to significantly inhibit cell activity within your cornea. Both aforementioned conditions are measured in what we call "dose time" AKA how long will you continue to look at the light source without adding a protective barrier and the study for both can be found here.
There's actually a pretty good argument for taking a digital detox. There have been several studies conducted that highlight the impact of screen reading on an individual's visual acuity. Seriously, check your screentime right now and buy yourself an overpriced superfood smoothie if it's under 4 hours. Staring at your screen can lead to the occurrence and development of poor eyesight and the higher incidence of nearsightedness correlates with the increase in the length of unfiltered dose time.
Part 5. Blue Light and your Beauty Sleep
Numerous studies have shown that blue light can regulate the body clock and promote alertness, memory, and cognition. The main mechanism is that blue light stimulates the secretion of melatonin which can increase or decrease cortisol expression depending on the time of day and regulate your circadian rhythm. When we're exposed to or consuming Blue Light in excess (especially at night when melatonin production peaks) it stimulates the brain, inhibits melatonin secretion, and increase corticosteroid production, thereby destroying hormonal secretion and directly affecting sleep quality.
Your eyes filter light. You're made of energy. Human beings are the original robots. Block Blue Light: Save face IRL filters create a crystal clear barrier between your eyes and your tech.
