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

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 body clock and suppress the production of melatonin, the sleep hormone. This can lead to sleep problems, decreased energy, and even long-term health problems. Therefore, it's essential to wear the right type of glasses that effectively block blue light. But how precise is this? Very precise! Even small differences in the quality of your glasses can have a significant impact on your protection. In this article, we explain why this is the case and how you can optimally protect yourself.

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 glasses that block 99.9%. But in practice, the difference is enormous. Even a small percentage of blue light reaching your eyes can activate your melanopsin receptors. These receptors, located at the bottom center 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's daytime, negatively impacting your sleep quality and overall health.

Glasses that block 99.9% of blue light therefore offer much better protection than glasses that block only 98%. The difference may seem small, but in terms of effectiveness, it's crucial. Glasses that block 98% might as well be thrown in the trash if you're serious about avoiding artificial light after sunset. This is how critical it is when it comes to artificial light and your health.

The 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 need to be completely sealed to be effective. The idea is that no artificial light should reach your eyes. While this sounds ideal in theory, in practice it's not necessary. Even with glasses that don't completely seal, you can still effectively protect your eyes from the harmful effects of artificial light.

Stray light is the light that reaches your eyes indirectly, for example, through reflections or light entering from the side. While this light isn't completely blocked by glasses that don't fully block out light, it has minimal impact on your melanopsin receptors. These receptors are primarily 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 impact on the effectiveness of the glasses.

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

How do you know if your glasses actually work?

With so many different brands and claims on the market, it's important to know if your glasses actually do what the manufacturer promises. A reputable manufacturer will not hesitate to share spectrophotometric data that shows how much light the glasses actually block. Some suppliers publish this data on their websites, while others make it available upon 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 offer this protection, so you can spend the evening with peace of mind without worrying about the impact of artificial light.

Don't worry about stray light or glasses that don't completely block out light. The most important thing is that you wear glasses that block almost all blue light. Our glasses offer just that: almost complete blockage of blue light and even some green light. This provides sufficient protection for your eyes and your body 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.
