What is Blue Light?

Blue Light: A Real Problem or Just Hype?

In recent years, "blue light" has become one of the most talked-about digital "boogeymen." Some say it seriously impacts sleep and well-being, while others dismiss it as just another modern fad. But what is the truth?

What exactly is blue light?

Blue light isn’t a mysterious new phenomenon. It’s a natural part of sunlight. During the day, it’s actually beneficial: it helps us stay awake, regulates our circadian rhythm, and supports focus.

The problem starts when we receive this light in the evening from artificial sources: phones, tablets, computers, and LED lights. These screens send a signal to our bodies that "it’s still daytime," which can easily disrupt the natural process of falling asleep.

Myths worth clearing up:

• "Blue light is harmful on its own." No, it isn't. The blue component of sunlight is natural. The issue is when and how much of it we get.

• "If you don't wear prescription glasses, you don't need a filter." Often, those who don't wear prescription glasses are the most exposed to digital light. Their eyes have zero protection.

• "Headaches are definitely caused by blue light." Not every headache is the screen's fault. However, consciously managing evening light exposure is a key part of a more balanced daily routine.

Why wear blue light blocking glasses?

Not because we are "sick." But because we want to prevent disruptive effects rather than treat them later. It’s like sunscreen: we don’t put it on because our skin is already burning, we apply it so it won’t burn.

Lumeresta glasses are designed for those who don’t want to give up their evening screen time but still value a restful night's sleep. This isn't a medical device or a miracle cure—it’s simply a smart step toward a more conscious evening routine.
