★★★★★
"I used to get terrible screen headaches and dry eyes by 3 PM. Since wearing the Day lens, the eye soreness is entirely gone. A total lifesaver for deep work."
JASON M.
★★★★★
"My sleep schedule was wrecked. Staring at laptops late meant I couldn't switch off at night. The Night lens physically calms my brain down. I fall asleep instantly now."
SARAH T.
★★★★★
"The two-step approach just makes sense. No more tension headaches during the day, and my circadian rhythm is finally back on track. Deep, restorative sleep."

Designed for screen-life
made for screens, meetings, and the hours after both
Study
Finals week. Ten tabs open. Amber keeps the screen strain out of your cram session so your eyes last as long as your notes do.
Work
Back-to-back Zooms and a deadline that won’t move. Amber cuts the glare so you’re still sharp at 5pm, not running on screen-fried autopilot.
Gaming
Ranked at midnight. Red blocks the blue light so a late session doesn’t wreck tomorrow’s energy. Play hard, sleep harder.
Wind down
Couch, Netflix, doom-scrolling the group chat. Red shifts the light so your evening screen time doesn’t push your bedtime back an hour.
Deep focus
Midway through a project that finally clicked. Amber keeps the monitor comfortable so flow state doesn’t end with a headache.
Relax
Instagram in bed “for five minutes.” Red keeps it sleep-friendly so your feed doesn’t steal your first hour of rest.
After Bed
11pm reply-all that couldn’t wait. Red protects your rhythm when you’re back on a screen past lights out.
Recovery
Session done. Cooling down with your phone while the body rebuilds. Amber softens the screen so your eyes get the same rest your muscles do.
Travel
Red-eye to Melbourne. Cabin glare and jet lag fighting for your attention. Amber takes the edge off so your eyes land fresher than your luggage.

"Honestly grabbed these because I was getting headaches from latenight screen sessions. I've been wearing the red pair after 8pm for about three weeks now and yeah, I'm falling asleep way quicker, I didn't change anything else."

"Had a pair of cheap blue light glasses before that did nothing. These actually feel different the night lens especially. It's like turning the harshness down on everything in the room, not just the screen. Really solid for the price."

TOP GLASSES
"I game most nights til midnight and these are the first blue light glasses that don't make everything look like garbage. Red lens colour shift is there obviously but you stop noticing after ten minutes. Build quality is legit too."

IT WORKS
"The amber ones are my daily drivers at work now. Subtle enough that nobody's asked me about them, which is what I wanted. Way less eye fatigue by the time I'm actually trying to sleep"
Good questions
BEFORE YOU BUY
Most blue light glasses are one-lens-fits-all, instead rhytm is mode-tuned built around how your light needs actually change across the day.
Day (Amber) reduces eye strain during bright-hour screen use. Night (Red) filters the spectrum that interferes with wind-down after sunset.
Day (Amber): morning through late afternoon, any time you're on screens in daylight hours.
Night (Red): after sunset. Put them on when you switch to evening mode. Whether that's work, TV, or scrolling before bed.
Night Lens is designed to support your body's natural wind-down by reducing the light spectrum that suppresses melatonin after sunset.
We don't promise outcomes. Sleep depends on your full routine. But removing a known interference is a good place to start.
Yes, that's one of the main use cases. Our lenses are designed for any screen or indoor LED light source: TVs, laptops, phones, overhead lighting.
Day (Amber) is tuned to stay clear and usable for daytime screens; colour shift is minimal.
Night (Red) is intentionally warmer. Colours will shift after sunset, that's the point. Your eyes adapt quickly.
Yes, within their intended environments. Day for daytime screens, Night for indoor use after sunset.
Avoid wearing Night for driving or any situation where accurate colour perception matters.
Dimming helps with glare, but it doesn't change the spectrum hitting your eyes. The wavelengths that affect melatonin and eye strain are still there at lower brightness.
Our lenses filters at the source, the light spectrum itself, not just the intensity.
Eye comfort is usually noticeable quickly. The wind-down benefit builds with consistency, especially if you make switching to Night part of your evening routine.
