How to recognize high-quality blue light glasses!

Why artificial light after sunset should be taken seriously and how to protect yourself optimally

Artificial light after sunset has a greater impact on our health than many people realize. The blue light emitted by artificial light sources can disrupt your biological clock and suppress the production of melatonin, the sleep hormone. This can lead to sleep problems, reduced energy, and even long-term health issues. That's why it's essential to wear the right type of glasses that effectively block blue light. But how important is this really? Very important! Even small differences in the quality of your glasses can have a big impact on your protection. In this article, we explain why this is the case and how you can protect yourself optimally.

The difference between 98% and 99.9% blocking

At first glance, blue light filter glasses that block 98% of blue light seem almost as effective as glasses that block 99.9%. But in practice, that difference is huge. Even a small percentage of blue light reaching your eyes can activate your melanopsin receptors. These receptors, located in the center at the bottom of your retina, are particularly sensitive to blue light coming from above. This is the type of light you normally receive from the sun during the day. When these receptors are activated by artificial light, your body continues to think it is daytime, which negatively affects your sleep quality and overall health.

Glasses that block 99.9% of blue light therefore offer much better protection than glasses that only block 98%. The difference may seem small, but in terms of effectiveness, it is crucial. If you are serious about avoiding artificial light after sunset, you might as well throw glasses that block 98% in the trash. That is how important it is when it comes to artificial light and your health.

Alina glasses are specially designed to block the entire blue light spectrum (380-520 nm) with an effectiveness of 99.93%. 

Stray light

Another frequently asked question is whether glasses must be completely sealed to be effective. The idea is that no artificial light rays should reach your eyes. Although this sounds ideal in theory, it is not necessary in practice. Even with glasses that do not seal completely, you can still protect your eyes from the harmful effects of artificial light.

Stray light is light that reaches your eyes indirectly, for example through reflections or light entering from the side. Although this light is not completely blocked by glasses that do not seal completely, it has a minimal impact on your melanopsin receptors. These receptors are mainly activated by light that enters your eyes directly from above, such as sunlight during the day. Stray light plays a much smaller role in this and has little effect on the effectiveness of the glasses.

Fully enclosed glasses can be useful in specific situations, such as when you are in an environment with extremely bright artificial light. But for most people, this is not necessary. As long as your glasses effectively block direct blue light, you are well protected.

How do you know if your glasses really work?

With so many different brands and claims on the market, it is important to know whether your glasses actually do what the manufacturer promises. A reliable manufacturer will not hesitate to share spectrophotometric data showing how much light the glasses actually block. Some suppliers publish this data on their website, while others make it available on request. Transparency is key here.

Alina glasses have been tested and proven effective. They block 99.93% of blue light and 98% of some green light (380-550). This means that with our glasses, you are assured of the highest quality and protection.

Conclusion: choose quality and protection

When it comes to artificial light after sunset, it's important not to compromise. Only glasses that block 99.9% of blue light offer the protection you need to optimize your sleep and health. Our glasses are specially designed to provide you with this protection, so you can enjoy your evening with peace of mind, without worrying about the impact of artificial light.

Don't worry about stray light or glasses that don't fit snugly. The most important thing is that you wear glasses that block almost all blue light. Our glasses offer exactly that: almost complete blocking of blue light and even some of the green light. This provides sufficient protection for your eyes and your biological clock, even if some indirect light reaches your eyes. Choose quality and effectiveness, and you can enjoy your evenings with peace of mind, without the harmful effects of artificial light.
