rhtym day+ night system
The complete two-step system to eliminate daytime eye strain and optimize your deep sleep.
Your calm, engineered
Amber lenses designed for deep focus, screen comfort and sustained daytime energy.
Switch modes on purpose
Red lenses engineered to signal your brain it's time to wind down and prepare for sleep.
Light hygiene, made easy
Light shifts. Screens don't
After sunset, your screens still blast daytime-spectrum light. Light hygiene starts with recognising the mismatch.
Spectrum over brightness
Dimming helps your eyes, but it doesn't change what your brain reads. Filtering the right wavelengths is what matters.
Two modes. One system
Amber for daytime screen comfort. Red after sunset for focus, then wind-down. Match your lens to your light.
Consistency builds it
Put them on at the same time each day. Your body learns the cue. That's light hygiene: a practice, not a product.
Compliments that speak FOR THEMSELVES
Actually works
"Been wearing the red ones every night for like 2 weeks now and i genuinely fall asleep faster. didnt expect much tbh but yeah its noticeable"
Daily driver
"amber pair lives on my desk at work. eyes dont feel as wrecked by 5pm anymore. Got the night ones too but the day pair alone is worth it honestly"
Solid for the price
"Had some cheap blue light glasses before that did basically nothing. These feel like an actual product. Night lens is strong but you get used to it quick"
Girlfriend noticed first
"She said I stopped scrolling in bed as long which is probably true lol. The red lens just makes everything feel calmer at night, hard to explain but it works"
Game changer for night shifts
"I work late on my laptop most nights and my eyes used to be destroyed by midnight. These took the edge off massively. Wish I got them sooner"
Not just tinted plastic
"Ive tried like 3 different blue light glasses before and they all felt the same and these actually feel different especially the red ones, the build is way better too"
Subtle enough for work
"was worried the amber ones would look weird on zoom calls but nobody has said anything, they just look like normal glasses which is exactly what i wanted"
Sleep is better no question
"Not gonna say its magic but I track my sleep and my deep sleep went up after about a week of wearing the red pair every night. Could be placebo idk but im keeping them"
Bought the system
"Got both pairs and honestly the switch from amber to red after sunset just becomes automatic. Feels like an actual routine now not just wearing glasses"
Way more comfortable than expected
"i wear glasses all day for work so i was worried these would feel annoying on top of that. theyre super light though forgot i had them on a couple times"
The red ones are intense but good
"First time putting on the night pair I was like wow everything is red lol but after 10 mins your eyes adjust and it just feels.. easier? like less sharp, I like it"
What you should know
How are these different from regular blue light glasses?
+
Most “blue light glasses” are one-lens-fits-all. RHYTM is mode-tuned:
Day (Amber) for bright-hour screen comfort, Night (Red) for after-sunset focus → wind-down.
When should I use Day vs Night?
+
Day (Amber): late morning → afternoon → late afternoon.
Night (Red): after sunset → bedtime (focus first, wind-down after).
Do they really improve sleep?
+
RHYTM Night is designed to support wind-down by reducing harshness from screens after sunset.
We don’t promise outcomes; results depend on your routine, light environment, and screen habits.
Can I wear them while watching TV?
+
Yes. They’re designed for screens and indoor LED lighting, including TVs, laptops, and overhead lights.
Do they distort colours?
+
Day (Amber) is designed to stay usable and clear for daytime screens.
Night (Red) is intentionally warmer for after-sunset use, so colours will shift more.
Are they safe for everyday use?
+
Yes, for their intended environments.
Use Day for daytime/afternoon screens. Use Night after sunset indoors.
Avoid Night for driving or situations where accurate colour perception is critical.
Is lowering screen brightness enough?
+
Dimming helps, but it doesn’t change the spectrum you’re exposed to.
That’s why RHYTM focuses on mode-tuned filtering, not just brightness.
How long before I notice results?
+
Most people notice comfort quickly. The “routine” benefit builds when you use it consistently — especially switching to Night after sunset.
