Here's how to recognize high-quality blue light blocking glasses!

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

After sunset, artificial light has a greater impact on our health than many people realize. The blue light emitted by artificial light sources can disrupt our biological clock and slow down the production of melatonin, the sleep hormone. This can lead to sleep disorders, low energy levels, and even long-term health problems. It is therefore essential to wear suitable glasses that effectively block blue light. But how do you go about it? With great precision! Even small differences in the quality of your glasses can have a significant impact on your protection. In this article, we explain why and how to protect yourself in the best possible way.

The difference between 98% and 99.9% blocking

At first glance, blue light filtering glasses that block 98% of blue light seem almost as effective as those that block 99.9%. But in practice, the difference is considerable. Even a small percentage of blue light reaching your eyes can activate your melanopsin receptors. These receptors, located in the center of the 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 believe that it is daytime, which affects the quality of your sleep and your overall health.

Glasses that block 99.9% of blue light therefore offer much better protection than those that only block 98%. The difference may seem minimal, but it is crucial in terms of effectiveness. If you really want to avoid artificial light after sunset, you might as well throw away your 98% blocking glasses. That's how important artificial light is to your health.

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

Stray light

Another frequently asked question is whether the glasses must be completely light-tight to be effective. The idea is that no artificial light should reach the eyes. While this may seem ideal in theory, in practice it is not necessary. Even with glasses that are not completely light-tight, it is possible to effectively protect your eyes from the harmful effects of artificial light.

Stray light is light that reaches your eyes indirectly, for example through reflection or lateral radiation. Even though glasses that do not completely block this light do not block it entirely, its impact on melanopsin receptors is minimal. These receptors are mainly activated by light that enters your eyes directly, such as sunlight during the day. Stray light plays a much smaller role and has very little effect on the effectiveness of the glasses.

Completely opaque glasses can be useful in certain situations, such as in an environment with very bright artificial lighting. But for most people, this is not necessary. As long as your glasses effectively block direct blue light, you are well protected.

How can you tell if your glasses are really working?

Given the multitude of brands and claims on the market, it is essential to check whether your glasses actually deliver on their promises. A reputable manufacturer will not hesitate to share spectrophotometric data indicating the level of light filtration. Some suppliers publish this data on their website, while others make it available upon request. Transparency is paramount.

Alina glasses have been tested and proven to be effective. They block 99.93% of blue light and 98% of certain wavelengths of green light (380-550 nm). With our glasses, you benefit from optimal protection and quality.

Conclusion: prioritize quality and protection

After sunset, when exposed to artificial light, it is essential not to compromise. Only glasses that block 99.9% of blue light offer you the protection you need for optimal sleep and health. Our glasses are specially designed to offer you this protection, allowing you to enjoy a peaceful evening without worrying about the effects of artificial light.

Don't worry about stray light or glasses that don't completely block light. The key is to wear glasses that block almost all blue light. Our glasses offer precisely that: almost total blocking of blue light and even some green light. They therefore provide optimal protection for your eyes and your biological clock, even if a little indirect light reaches your eyes. Choose quality and effectiveness, and enjoy your evenings in complete peace of mind, protected from the harmful effects of artificial light.
