The best glasses
I can really recommend the Hevo Sleep Lens! I sleep so well when I wear them in the evening. I've tried other evening glasses, but none have worked as well.

FRAME MATERIAL
Acetate
A premium, plant-based material made from renewable cotton and wood pulp. Itโs hypoallergenic, lightweight and durable โ and holds rich, glossy colour far better than cheap injection-moulded plastic. Itโs the material of choice for high-end eyewear.
LENS MATERIAL
Polycarbonate
Lightweight, ultra-durable, and impact-resistant. Polycarbonate lenses are up to 30% thinner and significantly lighter than standard plastic lenses, making them ideal for all-day comfort. They offer built-in 100% UV protection and high shatter resistance.
FRAME DIMENSIONS
- Ion: 47-19-150
- Ceres: 47-19-150
- Helios: 44-19-150
Fit might vary from different models but the acetate usually shapes after hour head when wearing.
EVENING STARTS AT THE EYE
There is an exact moment every evening when the body is ready to switch. The problem is that screens and indoor lighting delay it. Blue and green-adjacent wavelengths hit the retina and keep the brain in daytime mode โ melatonin is suppressed, cortical arousal stays elevated and the autonomic nervous system resists the parasympathetic shift. Sleep is postponed. This is not a habit issue. It is physiology.
HEVO manages the signal at the source. The lens absorbs 99% of blue light and blocks 100% of UV within tested ranges, with strong attenuation of transmission between 500 and 560 nanometres. That is sufficient to give the brain the night signal it needs: melanopic stimulation drops, wakefulness-driving input is removed and the warmer wavelengths that remain allow normal vision without interfering with wind-down.
The frame is built for consistent performance in evening environments. The full-size lenses reduce peripheral light entry from mixed indoor sources. Acetate temples hold alignment stable during extended wear. Optical-grade polycarbonate at 2.0 mm delivers uniform spectral blocking across the entire visual field โ not just straight ahead. Filtering values are laboratory verified and the glasses meet international optical standards.
Put them on from dusk to bedtime. That is all it takes to stop working against your own recovery.
MELATONIN DOES NOT RELEASE ON ITS OWN
The body produces melatonin when the eye's photoreceptors stop signalling daylight. The cells that control this โ intrinsically photosensitive retinal ganglion cells โ respond primarily to blue and green-adjacent light and signal directly to the suprachiasmatic nucleus. As long as those wavelengths are active, release is suppressed. Screens and indoor LED lighting are strong enough to hold the system in daytime mode well into the evening. Repeated over time, this strains nocturnal recovery and destabilises hormonal and metabolic regulation.
HEVO breaks that signal at the eye. The red lens absorbs 99% of blue light and strongly attenuates the adjacent green spectrum that drives circadian activation. When melanopic stimulation drops, the brain permits evening physiology โ neural activation decreases, the autonomic nervous system shifts toward parasympathetic recovery and the body begins its nocturnal sequence without competing signals.
The result shows in how you fall asleep and how you wake up. Sleep onset is faster when circadian timing is not being worked against. Sleep becomes more restorative when the system does not need to compensate for delayed release. This is not a placebo effect from darker lenses โ it is specificity. The lens removes the wavelengths that interfere. Everything else is left intact.
SLEEP QUALITY IS AN INPUT, NOT AN OUTCOME
Most people treat sleep as something that either happens or does not. In reality, the quality of the night is determined by what happens in the hours before it. Artificial light in the evening inhibits melatonin production, keeps cortical arousal elevated and delays the point at which the body can begin repairing tissue, regulating hormones and restoring energy. The effect is cumulative. A delayed sleep onset one night compounds the previous one. Recovery does not fail dramatically โ it erodes gradually.
HEVO addresses this at the only step that is actually controllable: light exposure before sleep. Through selective filtering of the wavelengths that drive circadian activation, the lens allows melatonin release to follow its natural curve. The body receives its signal on time. Sleep onset moves earlier. Sleep goes deeper and the body's repair sequences are more fully completed.
This is not about overhauling routines. It is about removing a specific obstacle. Evening screen use does not need to stop โ but its circadian cost can be eliminated. HEVO is built for that: uniform spectral blocking, stable fit and verified filtering values that actually deliver what the lens promises. Better recovery does not begin in bed. It begins at the light.
When light wavelengths between 400 and 550 nanometers (blue and green spectrums) hit the eye, specialized photoreceptors called ipRGCs alert the suprachiasmatic nucleusโthe central driver of your internal body clock.
This neural pathway halts melatonin release and pushes back your body's sleep schedule. Filtering out these specific wavelengths with red-tinted lenses blocks this disruption, allowing natural melatonin production to begin on time rather than being delayed by up to an hour and a half.

Really stylish blue light glassesโฆ
Really stylish blue light glasses with a clear effect! Definitely worth the price of around 1,000 SEK.
Nailed the price-quality - in love!
Honestly first thinking they were expensive. But in the end Lovely glasses, premium quality as expected and great filtering!!! The yellow ones using during daytime are great and the red ones before going to bed (when sun's almost gone). Really sets you in the mood to go to sleep - love them!!!
Very happy with the glasses andโฆ
Very happy with the glasses and the support I got, but above all with the effect on my sleep and recovery. Highly recommend!
I was sceptical whether they reallyโฆ
I was sceptical whether they would really improve my sleep, but after trying them for a few weeks now I really feel a big difference. Good quality glasses and great service!
sooo nice specs
they work well, you fall asleep sooo much easier โ if you struggle to fall asleep on time, buy these!
Bought one pair and ended up ordering moreโฆ
Bought one pair of glasses and ended up ordering several more afterwards. I'm very sensitive to blue light and these glasses were 10/10.
And what customer service โ it's rare to get such quick help and answers from an online store.
Super happy and can warmly recommend these glasses.

Really impressed
Really impressed โ they filter out blue light and I notice a clear difference in both eye strain and sleep quality. They sit comfortably on the nose and feel well made. Highly recommended!
what are you waiting for.. order
I've long been looking for glasses that would protect my eyes from blue light, since I sit in front of the computer quite a lot now that I'm studying. That in turn had triggered more migraine attacks and so on. After finding HEVO I ordered a pair, and the glasses deliver not only on materials but on looks too. They feel solid and they're worth the money. But most important of all: they've been so good and gentle on my eyes. I don't want to take them off, and my husband practically wants to wear them all the time, so he got a pair too, with the same lenses in the same model. We chose the ones with yellow lenses since you can wear them anywhere all day. If my eyes are tired one morning, they stay on from morning to evening. Warmly recommended โ I don't regret it for a second.

Strained eyes are a thing of the past! I work a lot and for long hours, which meant putting up with plenty of tension headaches and tired eyes. Not anymore!
Trusted by those who value rest
Elite athletes obsess over every variable โ training load, nutrition, recovery. Sleep is no different. HEVO exists for those who refuse to leave any edge on the table.

Same light. Two very different problems
The same light tells your body it is still midday
Wavelengths around 480 nm hit the receptors in your eye that set your body clock. They read that light as morning and hold melatonin back โ so at 23:00 at night your body is still running on daylight instructions, and sleep arrives late.
We recommend Sleep Lens or Relax Lens
In the afternoon your eyes have done 8h at 40 cm.
Screen light is blue-weighted and it never lets up โ as bright at nine in the morning as at four in the afternoon. Your eyes hold one focal distance for hours and blink about half as often as they should. The ache that shows up mid-afternoon is the bill for it. Use Focus Lens to filter out the right wavelengths.
We recommend Focus Lens
Why HEVO?
Most blue-light glasses hand you one filter and expect it to be right at nine in the morning and at eleven at night. The light changes across the day. The lens should too.
