Lab results you can trust
Most people choose blue light glasses to ease eye strain, headaches and the sleep problems that come with too much screen time. But if the glasses don’t actually block the harmful light, you’re not really protected.
Nattelyst glasses are documented to block almost all harmful blue light and UV — so your eyes get a rest, your sleep is less disturbed, and you protect your vision long-term.
It’s not just something we say — it’s tested and proven.

Watch out for big promises
Plenty of brands claim their glasses block 90–100% of blue light. But very few actually test them — and many block far less than they promise. At Nattelyst we don’t guess. We have independent labs document exactly what our glasses do, against the European Standard (EN/ISO 12312-1:2015), the Australian/New Zealand Standard (AS/NZS 1067:2016), and the American Standard (ANSI Z80.3-2015).
The results speak for themselves:
Elegant glasses against blue light
OBSIDIAN are our elegant, timeless blue light glasses, designed to protect your eyes from the harmful blue light coming off electronic screens.
If you spend hours in front of a screen, blue light glasses are worth considering. The harmful blue light those screens emit can cause eye strain, headaches and disrupt your sleep. With OBSIDIAN you protect your eyes effectively and avoid those negative effects.
It’s also really important to avoid blue light right before bed. The usual advice is to step away from screens a couple of hours before sleep — but if you’re still on the computer or phone late at night, picking up a pair of OBSIDIAN blue light glasses is a great way to protect your eyes and fall asleep more easily.
Only orange lenses block visible blue light
Visible blue light (380–500 nm) is light your eye can actually see. Blocking it requires an orange tint that absorbs the blue wavelengths — which is why lenses that genuinely block blue light are orange or amber.
UV light is something else. It strains and can damage the eyes, and clear lenses can block it effectively. Blue light from screens, however, affects the body’s sleep rhythm and can delay melatonin production. Blocking that requires filtering visible light.
Worth knowing: clear lenses that claim to block up to 98% blue light are usually only tested for UV — not for the visible blue light coming off screens.

Our results
The graph compares Nattelyst’s 98% glasses with typical untested blue-light glasses and ordinary clear lenses. Plenty of brands promise high blocking without any documentation — the graph clearly shows the difference once you actually measure the effect. Our glasses block almost all blue light, while untested products only stop a fraction — and ordinary lenses block almost nothing at all. If you want to avoid sleep disruption, headaches or eye fatigue, lab-tested glasses like these are the safe choice.
🎁 Free glasses case
When you shop with Nattelyst there’s always a free glasses case included. The case protects against scratches and bumps, so you can confidently take them in your bag, on a trip, or keep them by the bed.
It’s our way of saying thank you — and making sure your glasses stay looking good and working well for a long time. All you need to do is choose your glasses; we’ll handle the rest.

30% Glasses
Lets most blue light through. Perfect for daytime use, when you want to reduce eye strain without changing how colours look.
98% Glasses
Blocks almost all blue light in the 380–500 nm range. The slightly orange tint in the lens is what makes such high blocking possible — making them ideal for evening hours when you're winding down and preparing for sleep.
