Not sure? Our 30-day return policy has you covered.
- Clean lenses with a microfibre cloth only
- Rinse with lukewarm water if heavily soiled — never use paper towels or clothing
- Store in the case when not in use
- Avoid direct sunlight or high heat (e.g. car dashboards)
- Keep away from chemical cleaners, perfumes, and hairspray
Blue and green light in the 380–550nm range is what your brain uses to determine whether it is day or night. After dark, every screen you look at — your phone, laptop, TV — pumps this light straight into your retina.
- Blue light after dark suppresses melatonin production by up to 90 minutes
- This delays your circadian clock — you feel tired but wired, unable to switch off
- Crimson lenses block 99% of these wavelengths — the most effective barrier available in a wearable lens
- Wear them 2 hours before bed. Most users notice a difference within the first week.
This is not a placebo. Sleep is the foundation of everything — energy, mood, recovery, focus. These glasses protect it.
We stand behind every pair we ship. Here is what that means in practice:
- 30-day returns — if it is not right for you, send it back. No questions, no hassle.
- Quality checked — every frame is inspected before it leaves. If something is wrong, we make it right.
- Built to last —TR90 frames are flexible and resilient — not the kind of glasses that snap at the hinge after a month.
- Real support — if you have a problem, you are talking to a person, not a bot.
We think Nisalume is one of the best blue light glasses available at any price. We are confident enough to back that up.
The Nisalume Effect
Better sleep changes everything.
One pair of Nisalume glasses triggers a cascade — from how your body recovers to how your skin looks in the morning.
Physical Recovery
Deep sleep is when growth hormone peaks — rebuilding muscle, repairing tissue, and making last night's workout actually count.
Skin & Hair Regeneration
Melatonin is your body's most powerful antioxidant. Deep sleep drives collagen production, cell turnover, and hair follicle regeneration — the anti-aging protocol no cream replicates.
Immune Defence
Immune cells multiply during sleep. Quality sleep cuts sick days, accelerates healing, and keeps your defences sharp year-round.
Metabolism & Hormones
Poor sleep spikes cortisol and hunger hormones. Protect your sleep and you protect body composition, energy balance, and hormonal health.
Cardiovascular Health
Deep sleep lowers blood pressure, reduces inflammation markers, and gives your heart the nightly reset it depends on to perform at its best.
Mood & Mental Clarity
Sleep consolidates memory, regulates emotion, and sharpens focus. The most underrated performance tool isn't a supplement — it's a night of actual sleep.
For Your Skin
Sleep is the original beauty treatment.
While you sleep, your body produces melatonin — the most potent antioxidant it makes — alongside collagen that keeps skin firm and growth factors that reverse daily damage. Blue light at night shuts this process down early. Nisalume brings it back.
- Collagen production & skin firmness
- Reduced oxidative stress & cellular aging
- Hair follicle regeneration
- Reduced under-eye darkness & puffiness
- Improved skin hydration overnight
Nisalume doesn't just protect your eyes. We protect the hours your body needs to rebuild, regenerate, and perform. That starts with sleep.

What people are saying
★★★★★
"Complete sceptic. Put these on 3 nights in a row expecting nothing. I don't know what to tell you other than I actually fell asleep. Like, quickly. I've told 5 people about them since."
★★★★★
"I game until 1-2am. Started wearing these from 10pm. Within a week I was sleeping like a normal person again. No other changes. Just the glasses."
★★★★★
"Tried melatonin. Tried magnesium. Tried every sleep spray. None of it stuck. Wear these from 8pm watching TV and I'm actually tired by 10:30. I feel like an idiot for not trying this sooner."
★★★★★
"Night shift nurse. Sleep has always been a disaster. Tried a cheap pair from Amazon first, did nothing. These actually work. The lens is dark for a reason."
★★★★★
"My sleep therapist told me to get blue light glasses. Bought a cheap pair first — waste of money. These are what she was talking about. Noticeably different within 4 days."
★★★★★
"Got these for my partner as a joke gift. He texted me 5 days later saying he felt like a different person. We both have a pair now. Least funny joke I've ever made."
Simple by design
How it works
01
Put them on after sunset
Slip them on 2–3 hours before your intended bedtime. You don't have to change anything else about your evening — continue watching TV, scrolling, gaming, working.
02
99%of blue light is blocked
Thecrimsonlens filters the exact wavelengths (450–550nm) your brain uses to stay alert at night. Every screen you look at becomes safe for your circadian clock.
03
Melatonin rises. Sleep comes naturally.
Without the blue light signal keeping it suppressed, your body starts producing melatonin on schedule. You feel genuinely tired at the right time. You fall asleep faster. You sleep deeper.
Backed by research
The science behind blue light
In 2001, researchers at Harvard Medical School identified that light in the 460–480nm wavelength range — peak blue light — is the primary suppressor of melatonin production in the human brain. This research, expanded across studies in the Journal of Pineal Research and Applied Physiology, formed the basis of what we now understand about blue light and circadian rhythm disruption.
When you look at a phone, laptop, or TV after dark, you're exposing your retina to thousands of lux of blue light at exactly the wavelengths your brain uses to determine whether it's day or night. The suprachiasmatic nucleus — your internal clock — reads this signal and suppresses melatonin accordingly. The result: you feel wired even when you're physically exhausted. Sleep onset is delayed. Sleep quality suffers.
A 2014 study published in Proceedings of the National Academy of Sciences found that individuals who used light-emitting devices before bed took longer to fall asleep, had less REM sleep, and showed measurably lower alertness the following morning compared to those who read printed books under ambient light.
The Nisalume Night lens blocks99% of blue and green light in the 450–550nm range— directly targeting the mechanism behind evening melatonin suppression. This is not a placebo. The wavelengths are specific. The blocking is measurable. The effect on sleep is well-documented.

Questions answered
Everything you need to know
Do blue light blocking glasses actually work for sleep?
Yes — but the lens matters enormously. Clear "blue light glasses" with a thin coating block maybe 5–15% of blue light. That's not enough to meaningfully affect melatonin. The Nisalume Night uses a purpose-tinted lens that blocks99%of blueand greenlight in the 450–550nm range. This is the threshold where melatonin suppression actually changes. The tint exists for a reason — and it works.
How quickly will I notice a difference?
Most customers notice something within the first 3–7 nights — falling asleep faster, feeling genuinely tired at their normal bedtime, or waking up more rested. Some notice on night one. Give it at least a full week of consistent use before drawing conclusions. Your circadian rhythm needs time to recalibrate, especially if it has been disrupted for months or years.
Will everything look red through the lenses?
Yes — the crimson lens creates a warm red tint on everything you look at. This is by design and is exactly what makes it effective. Screens become noticeably dimmer and warmer-coloured. Most people adapt within a few minutes and find it actually feels more relaxing to look at than a regular bright screen.
Crimson or Amber — which should I choose?
Crimson (99%) is maximum protection — best for serious sleep issues, late-night gamers, high screen-time evenings, or anyone who wants the strongest possible melatonin protection. Amber (90%) is the gentler option — better for first-timers, casual evening TV, reading, or anyone who prefers a softer tint. Both work. Crimson works harder.
Can I wear these for gaming?
Yes — they're ideal for late-night gaming. Gaming monitors emit extremely high blue light levels, and gaming until midnight is one of the biggest sleep disruptors. Put them on before your session starts. Your performance won't suffer — and your sleep after the session will be significantly better than without them.
Are these only for nighttime use?
Yes — the tinted lens is designed for evening and night use only. Wearing them during the day would interfere with your daytime alertness, which relies on blue light exposure to regulate your waking state. For daytime screen protection, see the Nisalume Slim or Classic range — clear lenses, built for all-day wear.
What if they don't fit or work for me?
30-day returns, no questions asked. If they're not right for any reason — fit, feel, or you just don't notice a difference — send them back for a full refund. We're confident enough in the product to not need a complicated policy.
What's included in the box?
Your Nisalume Night glasses come with a protective hard case. Store them in the case when not wearing — the lens tint is durable but standard care habits keep them in perfect condition.

The science
Your brain thinks
it's still 2pm.
Every screen you look at after dark floods your retina with blue and green light — the exact wavelengths your brain uses to stay awake. Your melatonin gets suppressed. You lie in bed exhausted but wired. These glasses break that cycle.
- Blue light after dark delays melatonin by up to 90 minutes
- Your circadian clock gets pushed back — sleep quality suffers
- Two hours before bed is all it takes to protect it
The result
Wake up like
you actually slept.
Less tossing. Less lying awake with a racing mind. More of those mornings where you open your eyes and actually feel ready. That is what consistently protected melatonin does over time. It is a small habit with a real impact.
- Fall asleep faster — actually tired at bedtime
- Deeper, more restful sleep
- Better energy, mood, and focus the next day
Complete Your Eye Protection
Protect your eyes all day, every day.
Screens don't stop at sunset — and neither should eye protection. Add a daytime pair to complete your routine.

Customer Reviews
What people are saying
"Was sceptical, but my sleep has genuinely improved. I wear them from about 7pm and fall asleep so much easier. Super lightweight too -- barely notice them on."
"Honestly the best purchase I've made this year. Bought these and the Black ones. The packaging is beautiful and the glasses feel premium. Would recommend to anyone."
FAQ
Common questions
Yes. Our lenses have an anti-blue light coating that filters HEV blue light in the 380–500nm range — the wavelengths most associated with eye strain, disrupted sleep, and digital fatigue. The lenses look clear, so you won't notice any yellow or orange tint.
Barely, if at all. Unlike amber-tinted blue light glasses, Nisalume lenses are virtually clear. There's a very subtle shift in how warm colours appear, but for most people working on screens, it's not noticeable.
No — Nisalume glasses have non-prescription (plano) lenses. They're designed for people who don't need corrective lenses but want the benefits of blue light filtering. If you have a prescription, speak to your optometrist about adding a blue light coating to your regular lenses.
Absolutely — that is the idea. Our frames are designed for extended wear, and the lightweight construction keeps them comfortable even after hours on. Most daytime customers wear them throughout their workday. Night glasses are designed to be worn in the 2–3 hours before bed.
Both offer the same blue light blocking protection — the difference is purely the frame style. The Slim range features a sleek browline silhouette with a metal bridge. The Classic range features a round acetate frame — a bolder, more vintage-inspired shape. It comes down to personal style. Many of our customers own both.
We offer free returns within 30 days of delivery. If you're not completely happy, contact us at hello@nisalume.com and we'll sort it out — no questions asked. Items must be in original condition with packaging.
