North Ray blue light glasses vs. FL-41; why is North Ray a better choice?

The harmful effects of artificial light are an increasingly significant problem in today's digital world. Many people suffer from headaches, eye strain and poor sleep quality due to constant staring at screens. FL-41 lenses have been a well-known solution, especially for those suffering from migraines and light sensitivity, but North Ray lenses offer even more comprehensive protection against the harmful effects of artificial light. In this comparison, we will go through why North Ray is the better choice.

Feature FL-41 lenses North Ray lenses Migraine and photosensitivity management Filters out certain wavelengths to reduce migraine attacks Works perfectly as migraine glasses + filters out the harmful effects of artificial light to a greater extent Filterable light Some blue (480–520 nm) and some green light Artificial blue light from the entire blue light spectrum (380–500 nm) + an optimal proportion of green light, completely blocking the most harmful blue light peak (450 nm) Main purpose of use Reducing migraines and photosensitivity Migraine management + extensive body and eye protection from artificial light and circadian rhythm optimization Protection from screen light & LED lights Good, but not particularly designed Optimized for long-term use under artificial light Lens color Rose red/purple Yellow/orange, which mimics the spectrum of natural light Display clarity May distort color gamut Adapts color tones to match natural light without disturbing color distortion Filtration for day and evening needs No separate optimization for different times of day Lenses optimized separately for day and evening use Eye comfort during long-term use Relieves photosensitivity Reduces eye strain, protects sleep quality and prevents long-term light damage

Why are North Ray lenses better than FL-41?

✅ Migraine glasses + wider protection

North Ray's blue light glasses work just as well in migraine management as FL-41 lenses, but also offer very comprehensive and science-based protection against other harmful effects of artificial light.

✅ Wider light filtering

FL-41 only focuses on a specific narrow wavelength range, while North Ray's blue light glasses filter a wider range of blue light (380-500 nm) and also optimize the proportion of green light. In addition, North Ray lenses completely block the most harmful blue light peak (450 nm), which is associated with the greatest symptoms of eye strain, migraines and headaches.

✅ Supports natural circadian rhythm

North Ray lenses not only provide protection during the day, but also in the evening, helping to regulate melatonin production and improve sleep quality.

✅ Better comfort

FL-41 lenses can distort colors, while North Ray adapts color tones to match natural light without disturbing color shift.

✅ Designed for long-term use

FL-41 was developed primarily for migraine sufferers, but North Ray's blue light glasses are aimed at anyone who wants to protect themselves from the burdensome effects of artificial light, excessive glare, and the many other side effects of artificial light beyond just migraines.

User survey results – 100% felt they benefited from North Ray lenses

We conducted our own user study of chronic migraine sufferers, and the results speak for themselves: 100% of those surveyed felt they benefited from North Ray's blue light glasses . This further confirms the effectiveness of North Ray lenses in managing migraine and artificial light-induced symptoms.

The effects of artificial light on headaches and migraines – A research-based review

Artificial blue light, mainly produced by LED and display technologies, has been linked to headaches, eye strain, and poor sleep quality.

🔬 Studies show:

• Blue light (400–500 nm) activates retinal ganglion cells, which can trigger migraine attacks and increase photosensitivity (A. Noseda et al., 2016).
• Prolonged exposure to screens can cause digital eye strain syndrome, which includes headaches, dry eyes, and difficulty concentrating (Sheppard & Wolffsohn, 2018).
• The impact of artificial light on circadian rhythms is significant: in the evening, blue light reduces melatonin production, which can lead to sleep problems and further increase the risk of migraines (Chang et al., 2015).

North Ray lenses are designed to protect the eyes from these very effects, offering comprehensive protection for anyone who spends time in artificial light every day.

FL-41 or North Ray? The choice shouldn't be difficult

North Ray lenses offer everything that FL-41 lenses do – and much more. If you want lenses that not only relieve migraines, but also protect your eyes and support your well-being every day, North Ray is clearly the better choice.
