Please note: Absorption vs. Reflection

Nowadays, we spend a large part of our day behind screens... at the office, at home, on the road, and even just before bedtime. All that screen use means we are constantly exposed to artificial blue light. The consequences of this are increasingly well documented: tired eyes, disturbed sleep, and adverse effects on our biological clock and therefore our hormones.

It's no surprise that blue light glasses are becoming increasingly popular. But here's where many people go wrong: not all blue light glasses offer the same level of protection. On the contrary, most glasses on the market use a simple coating that only reflects a fraction of the blue light. At Alina, we believe that's not enough. We develop glasses that do what they promise: protect. And that starts with understanding the difference between reflection and absorption.

Absorption versus reflection: a fundamental difference

Blue light glasses can work in two ways: by reflection or by absorption. The technology used largely determines how effective the glasses are.

Reflection: superficial protection

Many cheaper blue light glasses use a blue reflective coating. That sounds logical, as the blue light is supposedly reflected back. In reality, however, the effect is limited:

• Only 10 to 20 percent of the blue light is actually reflected.

• Light that falls directly on the glass still reaches the eye.

• The coating may become damaged or worn over time.

• Reflection depends on the angle at which the light enters.
  

In other words: a reflective coating offers only partial and inconsistent protection, and often loses its effectiveness as the glasses age.

Absorption: protection from the core

At Alina, we have consciously chosen a different approach. Our glasses are designed toabsorb blue light rather than reflect it. The technology is in the lens, not on the lens. This offers a number of major advantages:

• Harmful blue light is absorbed and neutralized (converted into heat) immediately. Don't worry, you will never feel this heat.

• The effect is constant, regardless of the angle of incident light.
  

• The filtering is durable. It remains effective even after intensive use.

Our technology, tailored to the time of day

We offer two types of glasses, each optimized for a different use:

Evening glasses: Our glasses with red lenses absorb virtually the entire blue light spectrum (380–520 nm). The lenses are infused with pigments that absorb light and convert it into harmless heat. This makes these glasses ideal for use in the evening, in low light conditions, or before bedtime. They help support your natural sleep rhythm by not disrupting melatonin production.

Day glasses: For daytime use, our transparent (light yellow) glasses offer an excellent balance between protection and aesthetics. Although they appear colorless, they contain an advanced pigment layer that specifically absorbs harmful high-energy blue light (380–455 nm). Without visible coloring and without distorting your color perception. Ideal for people who work in front of a screen for long periods of time.

Your eyes deserve better

At a time when we are exposed to screen light for hours every day, investing in effective blue light glasses is not an unnecessary luxury. The difference between reflection and absorption is not just technical: it has direct consequences for your health, your sleep, and your productivity. Cheap solutions may seem attractive, but they rarely offer the protection they promise.

At Alina, we combine advanced technology with thoughtful design. Because we believe that your body deserves to be properly protected, not only today, but also in the long term.
