Our biology evolved over millions of years to live in tune with the cues and rhythms of nature. In an indigenous setting, after the sun sets, the only light you would see comes from campfires, candles, and the warm glow of embers. The Nightshades recreate that same low stimulation signal in the modern world - so you can still scroll, cook, or watch TV at night without sending your circadian rhythm into chaos.
Our Nightshade lenses cut 98.5% of melanopic green and blue light from 425-570nm, the range proven to suppress melatonin and disrupt sleep — while allowing a small amount of 400-420nm violet light to pass. This violet pass-through keeps color receptors partially engaged, restoring detail and color separation for evening activities like reading, socializing, or movie-watching.
Whether you’re under harsh LED lighting, winding down from a long day of screen use, or creating a healthier nighttime environment at home, the Nightshades keep you aligned with the natural signals your body depends on - without forcing you to live in the dark.

Wear the Nightshades in the hours after sunset or whenever you’re exposed to bright indoor light and screens at night.
They’re designed to block the green and blue melanopic light that tells your brain it’s daytime, while preserving just enough violet light to keep your world from turning into a dull red haze. This makes them perfect for real-life evening activities like watching movies, going out, or winding down at home.
For best results, put them on at least 1-2 hours before bed, and pair with warm, non-melanopic lighting like deep amber or red.
For most people, the difference in sleep onset is immediate with many noticing the increased sleep pressure on the first night.
Over the first week, you may find it easier to fall asleep at a consistent time and wake up more refreshed.
With consistent use, Nightshades help your body lock into a natural rhythm, making “wired but tired” late nights a thing of the past.
The Nightshades are designed for evening use, starting 1-2 hours before bed. They block nearly all sleep-disrupting green and blue light while keeping enough violet to preserve color perception. Wear them while using screens, under bright indoor lights, or in any environment that would otherwise suppress melatonin.
Absolutely. Unlike overly aggressive orange or red lenses, the Nightshades maintain functional color vision so you can still enjoy movies, read, and handle evening work without losing detail or clarity.
No. The engineered transmission profile preserves a touch of violet light, so your vision feels more natural than with traditional blockers. You’ll get maximum melatonin protection without living in a red haze.
Yes, by blocking nearly all green and blue melanopic light at night, the Nightshades help preserve your body’s natural melatonin production. This supports an easier transition into sleep, reduces the “wired but tired” feeling, and helps keep your circadian rhythm on track for deeper, more restorative rest.
Yes. Every pair comes with a durable protective carry case to keep your lenses safe when not in use.
The Onyx and Prism frames do not have an adjustable nose bridge however the rest do.
Yes, perfectly. Using the Nightshades alongside circadian-friendly lighting creates the most complete nighttime light protection possible.
The glasses block the sleep-disrupting spectrum while the Sky Portal in Deep Amber mode or Red Portal ensures the light in your space stays biologically aligned.

"I bought several pairs of lower quality glasses—a pair for $10, which stunk; a pair for $20, which stunk a little less, etc. I should have just purchased these to start with. I use them if I am working or watching screens after dark. They are dark (as they should be), but still of high enough quality that you can see what you’re doing once your eyes have adjusted."
"The Night Shade Horizon glasses have become an easy addition to my evening routine. They're a simple reminder to slow down, reduce bright light before bed, and be more intentional about winding down."
"Styling is terrific. Functionality is superb as they let in just enough color but still deliver on the core benefit of blue-blocking. Wear these after sunset for 45-60 minutes and it becomes impossible to stay awake. Only criticism is I wish they were a little bigger in lens diameter, as more of the peripheral sneaks into my field of view, than I'd like."
"I bought these thinking I could use them when I am using my laptop at night but that is not the case, they change the colors of the screen too much to the point that I can't read some stuff. I had to change to the orange ones (the daytime) and those works much better"
"Too bad they didn’t have a little reading lens like x2. 00 strength in the bottom of lens"
"They really shield your eyes but it messes with the coloring it's hard to watch TV with. But don't let me stop you from creating a good habit of shielding your eyes at night!!! Namaste, God bless!"
"I had other red night shades but could barely see while walking these are much easier to see"
"Finally jumped on blue light blockers and these really help at night to wind down much easier before bed"
"Found them incredibly helpful for improving sleep and eye strain."
"They totally block out blue lights and focus it all on the red spectrum. Totally helps me chill 🤙✌️❣️"
