Complete Blue Light Protection

Blocks 99.9% of blue and over 97% of green light (up to 600nm)

Built for Night - Sunset to Sunrise

Engineered for evenings, late nights, and pre-dawn hours

Fall Asleep Faster & Sleep Deeper

Wear 2 hours before bed for deeper, more restorative sleep

Description

Horizon Night+ features our most advanced lens, engineered to block the specific wavelengths of artificial light that interfere with sleep after sunset.

By suppressing 99.9% of blue light and over 97% of green light (up to 600nm), Night+ allows your brain to recognise true night-time conditions. This supports your body’s natural wind-down process, helping you fall asleep more easily and experience deeper, more restorative sleep.

Designed for use 2–3 hours before bed, Night+ is ideal for indoor lighting, evening screen use, shift work, travel, or any environment where artificial light extends past sunset.

Built not just to reduce light, but to protect your sleep rhythm.

Frame Details

Bold and confident, Horizon redefines contemporary edge with a striking geometric silhouette and architectural bridge. Crafted from durable, lightweight acetate, its oversized proportions and commanding shape are both modern and timeless. A statement piece that doesn’t ask for attention - it holds it.

The Science

Artificial light after sunset does more than stimulate the eye - it influences circadian timing. The wavelengths most responsible for suppressing melatonin fall within the blue and green spectrum (approximately 380–600nm).

Most night-time lenses focus primarily on blue light reduction.

Night+ is engineered to go further.

By suppressing 99.9% of blue light and over 97% of green light across this range, Night+ delivers full-spectrum post-sunset filtration. This reduces the light signals that delay natural melatonin onset and shift your internal clock later.

The deep red tint is not aesthetic - it is calibrated to minimise stimulation while maintaining functional indoor visibility.

This is our most complete circadian lens.

Designed for environments where light hygiene is non-negotiable.

Through the Lens

This Is What Night Should Look Like

The deep red shift isn't a side effect - it's the mechanism.
Night+ removes 99.9% of blue and over 97% ofgreen light, leaving only the wavelengths your brain associates with darkness. What may look intense initially, is exactly what your biology has been waiting for - Biological Darkness.

The world doesn't disappear. Your screen still works. You can still work. Your conversations still happen.

But for the first time after sunset, your brain finally gets the signal that it's night.

Atlas yellows actually look unreal and can be worn all day in office or at home because everything still looks so crisp through them. They’re comfortable af and look better than my Dr Franklins and Raybans so I even wear them out unless I need my actual sunnies.

Horizon Night pair do an insane job too.

Game changers! I thought it would blur my screens/make everything mono colour but it literally makes everything so crisp. Got horizon Night to go with them and they are unreal too.

Unless I’m needing my ACTUAL sun glasses, these will replace my fashionable pairs of raybans and Dr Franklins for the forseeable future. Fit so well on the face unlike most my other sunnies that I need to take off to every now and then.

Wouldn’t bother buying from any other company if blue light blocking & all day comfort with style is what you’re after.

Lightweight, great fit, and super comfy. Good for those like me with a narrow face and don’t want to feel like you’re wearing costume glasses

My eyes INSTANTLY felt less strained. As someone who is constantly in front of a screen I was actually shocked how my eyes felt as soon as I put on these glasses. I am so excited to see long term affects as in this short while I already can focus better and my eyes don't feel sore. On an aesthetics level, i am obsessed with the branding . The quality of these feel beautiful as well- they feel solid and not cheap. Highly recommend if you're someone who is in front of a screen a lot.

These Horizon Night Red glasses are fantastic, beautifully made and very stylish (they even make this old bloke look cool!). Since I started wearing them, I fall asleep much faster once I’m in bed. They’ve become part of my nightly routine, and I wouldn’t be without them. Highly recommend!

I've been wearing the Alba - Night Red blue light blocking glasses for a few weeks now, and I've noticed a significant improvement in my sleep quality. Wearing them in the evening has helped reduce the overhead lights and my screen time's impact on my sleep + they’re comfortable to wear and stylish too! Couldn’t recommend more😊

The Mechanism

Protect your sleep

Your brain uses light to tell the time. Not a clock on the wall. The light coming through your eyes.

When you look at a screen after dark, your brain reads that light as daylight. So it holds back the sleep hormone (melatonin), keeps your stress hormone (cortisol) running, and waits for the light to change. It does not matter how tired you feel. Until the signal changes, your body stays in daytime mode.

Night+ removes that signal. Your brain gets the cue it has been waiting for, and the process of winding down can finally begin.

The 2 Hour Protocol

Wear 2 hours before bed for deeper, more restorative sleep

our body begins preparing for sleep long before you close your eyes.

Around 2 hours before your natural sleep time, melatonin starts to rise, your core body temperature drops, and cortisol begins to fall. This is your biology's most important window. Artificial light during these hours does not just delay sleep onset. It disrupts the entire cascade: compressing deep sleep, delaying growth hormone release, and leaving your cortisol running when it should already be winding down.

Worn during these 2 hours, Night+ removes the wavelengths your body is most sensitive to, so the process your biology has already started can continue uninterrupted.

See the full article - Why the 2 hours before bed matter most

Beyond Any amber lense

Our most advanced lens. Blocks both blue and green light.

Most people know blue light affects sleep. Fewer know that melatonin suppression does not stop there.

Green wavelengths, up to 600nm, are equally capable of telling your brain it is still daytime. Night+ filters 99.9% of blue light and over 97% of melatonin-suppressing green wavelengths up to 600nm, independent spectrometer verified. The most comprehensive spectral coverage in the Balterra lens system, and the most complete filter available for the hours before bed.

The Right Light at the right time

When to Wear

Designed for Sunset to Sunrise

Our red Night+ lenses are designed for moments when any artificial light exposure can delay melatonin and disrupt deep rest.

Wear them from sunset to sunrise, including the early hours of the morning if you wake before daylight. Whether you’re winding down at night or navigating artificial light before dawn, these lenses shield your rhythm when it matters most.

Wear them:
– During your nighttime routine under indoor lighting
– While watching TV, scrolling, or reading at night
– In the early morning before sunrise
– During sleep interruptions (e.g. caring for a newborn)
– While travelling across time zones or on night shifts
– In any artificial light setting after sunset

Not for use during the day or outdoors.

For earlier evening wind-downs, choose our Amber Night Lens. For daytime protection, explore the Yellow Daylight Lens.

Frequently asked questions
When Do I wear my Balterra Blue Light Blocking Glasses

Use Daytime lenses during the day in indoor or screen-heavy environments to reduce eye strain and support focus. Switch to Night (Amber) in low‑light evening settings—dim lamps, or go Night+ (Red) under intense artificial light—TV's, phones, LEDs, or overheads—for complete circadian protection.
Can I wear my Balterra Glasses All Day

Yes — when indoors and exposed to artificial light. Our lenses are designed to support your circadian rhythm by filtering overstimulating blue light from screens and LEDs.

However, they’re not intended for natural sunlight. For best results, wear them inside — and let real daylight reach your eyes when outdoors.
When will I get my order?

Orders are typically processed within 1–2 business days. Once dispatched, you’ll receive a confirmation email with tracking details so you can follow your delivery in real time.

Please note: during peak periods or product launches, dispatch may take slightly longer — but we always aim to get your order to you as quickly as possible.
Can I wear Balterra glasses with contact lenses or prescriptions?

Absolutely. Our non-prescription glasses are perfect for contact lens wearers. If you need prescription lenses, we’re working on custom RX options — stay tuned.
What if the frames don’t suit me?

We offer a 30-Day Right Fit Guarantee. Try them on at home — if the fit isn’t quite right, return them in reasonable condition and we’ll help you find the right pair or issue a refund.
