FRAME MATERIAL
Acetate
A premium, plant-based material made from renewable cotton and wood pulp. It’s hypoallergenic, lightweight and durable — and holds rich, glossy colour far better than cheap injection-moulded plastic. It’s 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.
BUILT FOR THE SCREEN DAY
Long screen sessions keep your eyes locked at one distance under bright, blue-heavy light. That is when eyes start to feel dry, heavy and strained, and focus begins to slip in the afternoon. Focus Lens is made for those hours.
The yellow-tinted lens filters 84% of blue light – the shortest, harshest wavelengths from screens and LED lighting – and lets the rest of the spectrum through. It cuts the glare without distorting colour, so your monitor still looks like your monitor.
A DAYTIME LENS, NOT A SLEEP LENS
Focus Lens is deliberately lighter than Relax and Sleep. During the day you want light to keep you alert; the goal is to take the edge off the screen, not to tell your body it is night. When evening comes, switch to Relax Lens or Sleep Lens.
THE FRAME
Acetate frames that hold their alignment through a full workday, and 2.0 mm optical-grade polycarbonate lenses that filter evenly across the whole field of view – not just straight ahead.
Blue light sits at the short, high-energy end of the visible spectrum, roughly 400–500 nanometres. Screens and LED lighting emit a strong peak around 450 nm. Some of that light during the day helps keep you alert – but hours of close screen work under it are commonly linked to digital eye strain: tired, dry or heavy-feeling eyes and headaches.
Focus Lens filters 84% of blue light and leaves the rest of the spectrum in place. That reduces screen glare without dimming your day. In the evening the body needs a stronger filter to let melatonin release on time – that is what Relax Lens (97%) and Sleep Lens (99%) are made for.
We offer free shipping on all glasses with 3-6 days delivery time. Delivery time vary depending on country. ReturnsWe offer 30 days return. Cost of return for EU orders is €9 and International orders is $20.

What happens in your first 7 nights.
Day 1–3You actually wind down
- Sleep Lens on 1–2 h before bed
- Screens and lamps feel softer
- You fall asleep without tossing and turning
Day 5Tired at the right time
- Your body finds its rhythm
- You get tired around the same time every evening
- Mornings feel easier
Day 7You've become someone who winds down
- Focus Lens at the computer, Sleep Lens in the evening
- You notice the difference when you're not wearing them
Experiences vary from person to person.
Isn't it just placebo?
Fair question – which is why it has been tested against placebo.
- Columbia University, 2018: with blue-light-blocking glasses, people with sleep problems slept about 30 min longer on average than with clear placebo glasses.
- Burkhart & Phelps, 2009: better sleep and mood than with glasses that didn't stop blue light.
- Gooley et al., 2011: ordinary room light before bed shortens the body's melatonin period by about 90 min.
Clear blue light lenses filter too little to make that difference. Sleep Lens filters up to 99% – and you test it yourself for 30 nights.
I already use Night Shift. Do I need this?
Night Shift and similar night modes only remove about 30% of blue light – not even enough for the screen you're looking at. And the ceiling light, the TV and the rest of the room still shine as usual. Sleep Lens filters up to 99% of blue light from everything you see.
Which two pairs should I choose?
Focus for the screen during the day and Sleep for the evening is the most common pick. Relax suits the early evening hours.
What if they don't work for me?
You have 30 nights. If winding down doesn't feel easier, send them back.

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 – it's rare to get such quick help and answers from an online store.
Super happy and can warmly recommend these glasses.

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 – 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 — 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 — 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 — 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.
