Miksi sinivalon filtteröinti illalla on tärkeää?

Exposure to blue light in the evening is a growing phenomenon. This exposure has numerous adverse effects, including on health and efficiency. In this blog, we will discuss the reasons why blue light glasses are especially important at night and how they can help improve both your sleep quality and your overall well-being.

What is a blue light?

Blue light is part of the visible spectrum of light emitted by digital devices, especially computers, tablets and smartphones. While blue light itself is a natural phenomenon, excessive exposure to blue light from digital sources, especially before bedtime, can be harmful. Blue light determines a person's circadian rhythm, as the body starts producing melatonin in the evening when blue light no longer reaches the eyes. Studies have shown that blue light can disrupt sleep patterns and cause eye strain, which can lead to more serious visual problems in the long term.

Why is it important to filter blue light at night?

Blue light penetrates deep into the structures of the eye and interferes with the production of melatonin, the so-called 'sleep hormone'. This process can disrupt the body's natural circadian rhythm, which can lead to sleep disturbances and reduced sleep quality. If you use digital devices in the evening before going to bed, you should definitely wear blue glasses. The glasses filter out some of this harmful light, helping your body to maintain normal melatonin levels.

Normal melatonin production promotes faster falling asleep and deeper sleep. In today's world, where sleep is often disrupted by stress and rush, wearing blue glasses can be an effective way to ensure you get the most out of every moment of rest. In this way, blue glasses not only improve immediate eye health by reducing strain, but also support wider health and wellbeing.

How do blue lenses work?

Blue light is known for its ability to disrupt sleep patterns and cause eye strain, which is why filtering it is important, especially at night. Blue light glasses are specifically designed to prevent blue light from entering the eyes. The lenses in these glasses are usually lightly pigmented, which helps filter out harmful light. They can be either completely clear or tinted, depending on the level of filtering the user needs. Oscar Blue offers both clear and "enhanced" lenses. Enhanced lenses are tinted orange and filter blue light better than the standard models.

As well as improving sleep quality, blue glasses can help reduce eye strain caused by staring at a screen. By wearing blue lenses regularly, especially in the evening before bedtime, you can help your body prepare for rest and promote natural melatonin production, which is essential for good sleep. This is particularly important for people who spend much of their day exposed to blue light from digital screens.

Who needs blue light lenses?

While filtering blue light during the evening is beneficial for everyone, it is particularly important for the following groups:

  1. Office workers: if you spend most of your day at a computer or other digital device, blue light lenses can help reduce eye fatigue and improve concentration.
  2. Night workers: those who work mainly at night spend a lot of time in artificial lighting and possibly at a display terminal. Blue light glasses are particularly useful in this situation.
  3. Students: Students who spend long hours studying on digital devices can use blue lenses to protect their vision and improve sleep quality.
  4. Gamers: Intensive staring at a screen while gaming can cause significant eye strain, which is why blue lenses are popular among gamers. For more information on the use of blue glasses in gaming, click here.

Summary

Filtering blue light during the evening is a simple but effective way to promote health and well-being. Blue glasses offer a simple solution that helps both to improve sleep quality and to reduce eye strain. If you spend a significant amount of time on digital devices, consider getting blue glasses at least for evening use.
