Kronveil x0-1
Unisex$200.00 $99.00 USD
Engineered for screen-heavy workers who refuse to let their nights pay for their days.
Without Protection
Most blue light glasses block the wrong light.
The 415-455nm range is the part of blue light that disrupts your sleep, strains your eyes, and triggers headaches. Most blue light lenses barely touch it. The X0-1 blocks 99% of it, plus the short-wavelength green light your brain also responds to after dark.

KRONVEIL X0-1
99%
Blocked at 415-455nm.
X0-1 lens with dip-dye filtration built into the polymer itself, not a surface coating. |
CLEAR "BLUE LIGHT" LENSES
~15%
A cosmetic coating on basic polycarbonate.
Barely filters the wavelengths that actually keep you awake at night. |
|
Better Sleep
Blocks the light that tells your brain to stay awake. Wear them 2 hours before bed and your body can actually wind down.
|
Less Eye Strain
Cuts the harshest light your eyes deal with on screens. Less squinting, less dryness, less of that burning feeling by 6pm.
|
|
Fewer Headaches
Screen migraines start with high-energy light hitting your eyes for hours. The X0-1 takes that load off before it builds.
|
Sharper Focus
When your eyes aren't fighting the light, your concentration holds longer. The kind of improvement you feel by the end of a work session.

Blue Light Filtration — 415–455nm
With X0-1 Lens Protection
March 18, 2026
Sleep changed within a week
I've tried four different blue light glasses over the past two years. These are the first ones where I actually noticed a difference. Falling asleep faster and waking up without that groggy fog. The build quality is serious too — solid acetate, no creaking.

Finally, ones that actually work
I sit in front of screens 10+ hours a day for work. Used to get brutal headaches by 4pm. Two weeks in with these and the headaches have basically stopped. The case and packaging feel premium too — nice touch.

Great lens, slightly tight fit
The filtration is genuinely impressive — I tested with a spectrometer at work. Only knock is the frame feels slightly narrow on wider faces. After a few days it loosened up. Would still recommend.

Zero eye strain after long sessions
I code for 8-10 hours a day. By evening my eyes used to burn. These completely fixed it. The lenses are crystal clear too — no yellow tint like cheap pairs. Worth every dollar.

Good glasses, slow delivery
The glasses themselves are solid — well built, nice lens. But it took almost three weeks to arrive in Melbourne. For the price point I expected faster shipping. Glasses are great though once they arrived.

Headaches gone completely
I was skeptical about blue light glasses in general. My optometrist actually suggested I try a pair that blocks the 415-455nm range specifically. These do exactly that. Headaches from screen time are gone. Convinced.

Scandinavian winters need these
During dark Swedish winters I'm on screens constantly. These have made a noticeable difference in my sleep cycle. The design is clean and minimal — exactly my taste. The case is beautiful too.

Too expensive for what it is
The glasses work fine and the build is decent, but I don't think they justify the price. You can find similar filtration specs for half the cost. The packaging is nice but I'd rather save the money.

Very good quality, clear lenses
Most blue light glasses have an obvious yellow cast. These are nearly perfectly clear. Build quality is excellent — the hinges feel like they'll last years. Only wish the temple arms were slightly longer.

Exceptional craftsmanship
The build on these is something else. Solid hinges, no flex, the acetate feels premium. I've worn them daily for a month and they still look brand new. Light enough to forget you're wearing them.
January 18, 2026
Fall asleep faster every night
I put these on two hours before bed as recommended. Within the first week I noticed I was falling asleep 20-30 minutes faster. No more lying in bed staring at the ceiling. Game changer for me.
January 12, 2026
Didn't notice any difference
Wore them for three weeks straight and honestly didn't feel any change in eye strain or sleep. Maybe it works for others but not for me. Build quality is fine but returning them.

Worth every cent
Full day of coding with eyes feeling completely fresh by evening. I've never had that experience before. The unboxing experience is premium — magnetic case, microfiber cloth, everything feels intentional.

Stylish and functional
These look good enough to wear outside, not just at a desk. The frame design is understated and elegant. Filtration works well — tested it with my phone's blue light at night. Slight pressure on the nose bridge after 6+ hours.

Bought two more for gifts
Got these for myself and immediately ordered two more as Christmas gifts. Everyone loves them. The packaging alone makes it feel like a proper luxury gift. The filtration is the real deal — my mum said her migraines have reduced.
