In some bitcoin circles, there’s this idea that blue light, the kind that comes from screens and other artificial sources, is considered “fiat.” The thinking is that you should block it to fix your circadian rhythm, reduce your eyes strain and sleep better. Instead, they suggest embracing natural light, which they see as the “Bitcoin” of light.
That’s where Chroma comes in. Known for their work with red light therapy and more, they created the Chroma Nightshades, glasses designed to block blue and green light effectively, all while looking good. They come in a range of styles, so you’re not stuck with just one look.
In this review, we’ll take a close look at the Chroma Nightshades to see if they’re actually worth it. I’ve been using them for quite a while now, so I’ll share whether they helped with eye strain, sleep, and overall comfort. Keep reading to find out how they performed.
What Are The Chroma Nightshades?
The Chroma Nightshades glasses are a unique type of evening eyewear built specifically to filter out the kind of light that messes with your sleep, without completely stripping the world of color. Most blue-blocking glasses turn everything into a deep, reddish haze, which can be jarring, especially if you're trying to watch a movie or get some work done. Nightshades do it differently.
They're designed to block almost all the wavelengths that disrupt melatonin production, while still letting in just a trace of violet light. That tiny sliver is enough to keep your sense of color intact, especially on screens or in harsh artificial lighting. The result? You can still see purples, blues, and other tones that would normally disappear behind a heavy red lens.
They’re also mirrored, silver, to be exact, so they look slick while they’re working in the background to protect your circadian rhythm. Whether you're finishing up late-night work, scrolling through your phone before bed, or watching something in dim lighting, Nightshades let you do it all with minimal impact on your sleep quality.
In short, they’re not just sleep-friendly, they’re life-friendly.
Chroma Nightshades Glasses Main Features
Nightshades glasses are built for people who live in the real world, not just in sleep labs. They filter out the wavelengths of blue and green light that are known to interfere with melatonin production, essentially helping your body understand it’s time to wind down, even if you’re surrounded by bright screens or LED lights. But unlike traditional orange-tinted lenses that leave you seeing the world in murky red tones, these let a sliver of violet light (400–420nm) through. That tiny detail makes a big difference, letting you maintain your sense of color in the evening without sacrificing protection.
Here’s what sets them apart:
- Melatonin Protection
Nightshades block almost all of the sleep-disrupting light range, shielding your body’s ability to produce melatonin naturally. That means better sleep, starting before your head even hits the pillow. - Reduced Sleep Latency
By filtering out the wavelengths that keep your brain stuck in “daytime mode,” Nightshades help you fall asleep faster once you do head to bed. - Color You Can Actually See
You’re not stuck in a red-tinted cave. Nightshades keep enough color perception intact for evening tasks like watching movies, reading, cooking, or chatting with others—without that weird washed-out look. - Socially Compatible
Designed for real life. These glasses don’t scream “biohacker,” so you can wear them during dinner, on video calls, or out for an evening walk without looking out of place. - Engineered Violet Pass-Through
The lenses are finely tuned to allow just the right sliver of violet light through. This keeps your color receptors partially active, which helps your eyes differentiate colors more naturally in low-light environments. - Multiple Styles, Same Protection
Whether you prefer something sleek like Onyx or a bold look like Prism or Agent, Nightshades frames come in five different styles. The filtering tech stays consistent, but the aesthetics give you flexibility. - 30-Day Satisfaction Guarantee
Not feeling it? You’ve got a full month to try them out. If they’re not a fit, just send them back for a full refund.
All in all, these are the kind of blue light blocking glasses that don’t feel like a compromise. They’re protective, functional, and wearable in real life, whether you’re winding down or just trying to survive a late shift without wrecking your sleep.
Chroma Nightshades Unboxing
The Chroma Nightshades arrived at my doorstep in a sturdy box, with the case and glasses neatly packed inside. Since they were shipped from the US and I’m based in Europe, I had to pay about 30 EUR in import taxes. Naturally, if you’re in the US, you won’t have any additional import fees.
The case stands out with the elegant Chroma logo, has a premium finish, and closes securely with a magnetic latch.
The items included in the purchase are the following:
- 1× Chroma Nightshades Glasses
- 1× Cleaning Cloth
- 1× Case
The glasses come well protected, with plastic covers on the arms and an additional one on the lenses. Once removed, the glasses were in perfect condition.
One thing I noticed right away is the excellent build quality of the glasses. Every detail is carefully designed, like the nose pads, which have a unique shape that keeps the glasses securely in place and fits all face types.
Another feature you’ll notice immediately is the outer layer, which has an “metallic” finish. It keeps the glasses looking sleek and elegant, so nobody will realize you’re wearing blue/green-light blockers. In my tests, the lenses effectively filter out blue and green light letting in just a trace of violet light, making daily screen time feel much more comfortable and relaxing.
On the sides, the glasses features the Chroma logo.
Are they really useful?
You might think that built-in filters on devices, like Night Shift on Macs, which make the screen look more orange, are enough. But they’re not. The screen still emits blue light, even if our eyes don’t notice it. That’s why a proper, physical filter is necessary. The same goes for warm white LED bulbs.
Using one makes screen time a bit easier to handle. You can dive into exciting ideas, code, or finish up work late, without further messing with your already imperfect circadian rhythm. It blocks blue light very effectively, so you do need to turn up your screen brightness to read comfortably.
