Blue light exposure at night

In today's fast-paced, tech-driven world, we're constantly surrounded by screens and artificial lights.

Although these advancements have revolutionized our daily lives, they've also introduced a new set of challenges for our health that our species has never faced.

One of the most significant of these challenges is the exposure to blue light.

So… what exactly is blue light?

And why is it a concern?

Let's dive deep into the science and discover what we can do to protect ourselves from the damaging blue light that is rampant in our modern environments.

The Problem with Blue Light

Why Block Blue Light?

Our bodies operate on a natural rhythm known as the circadian rhythm. This internal clock synchronizes our biological processes with the day-night cycle, ensuring that we're alert during the day and restful at night.

For millennia, this rhythm has been consistent, with our bodies relying on the natural light of the sun to regulate our internal processes.

The sun lets our biology know when it’s time to start activating our metabolism, and producing the key hormones and neurotransmitters that we need to function at our best.

However, the advent of artificial light has disrupted this natural rhythm. And comes with a significant cost to our health, well-being, and general mood. By extending our waking hours past sunset and spending more time indoors away from natural sunlight, we've introduced two main detrimental effects:

Blue light exposure at night

Daytime Dissonance

Artificial light sources during the day cannot properly mimic the sun's full spectrum of light. They are static, meaning that they do not change in light quality as the sun does throughout the day.

Additionally, they emit light that is very different from the sun (i.e., harmful).

Artificial light stimulates our hormonal system to keep us awake and active in our hyper-productive society.

But it doesn't provide the full spectrum of wavelengths necessary to power healthy cellular activity.

Ultimately, this leads to an energy imbalance in our cells, and in turn, inflammation.

This negative effect is most profound in our retina, which is completely exposed and very sensitive to all light due to its high energy consumption.

Evening Exposure

Artificial light exposure after sunset tricks our brain into thinking it's still daytime, even if we are far away from natural sunlight. This deception prevents our body from producing melatonin, a crucial antioxidant responsible for sleep regulation, anti-aging, cancer prevention, and many other surprising benefits.

As we’ve all felt after a night of poor sleep, reduced sleep quality and duration can lead to immediate consequences to our well-being—emotional volatility, brain fog, lack of focus, and much more.

Additionally, the research shows that a reduction in sleep quality or duration can lead to severe long-term health issues.

This is why it’s essential that we do not disrupt our body's production of melatonin; instead, we should be actively seeking the best lifestyle modifications and products to enhance it.

So, what is the best solution to protect us restore our body’s natural rhythms and protect us from health issues caused by the unavoidable blue light in our modern world?

⭐⭐⭐⭐⭐ A Game-Changer For Restful Sleep

Ra Optics Blue Light Blocking glasses have been a complete game-changer for my sleep. As someone who spends long hours in front of screens, I was skeptical at first. But after trying them out, I am amazed at the results. These glasses have drastically improved the quality of my sleep by reducing my exposure to blue light. I fall asleep faster, and wake up feeling more refreshed and energized. They are comfortable to wear and the clarity of the lenses is exceptional. If you're looking for a simple and effective solution to improve your sleep, I highly recommend giving Ra Optics a try.


I have been wearing 'blue light reading glasses' at night for years as I spend a lot of time on my computer. I don't sleep well and when I started wearing them the first night, I started to get tired much earlier in the evening. It has made a difference to me in relaxation and calming down in the hours we we are supposed to!!! Thank you Ra Optics. Much love. - Christine C.
