During winter, my friend in the UK uses light meter app to track lux. However, it is not accurate and very annoying to take out a phone to track it everytime, and you dont know if you receive enough light.

Therefore, I want to develop a glasses that can track Melanopic EDI (how light affects the human body clock) 24/7 to see whether you receive enough light in the day and too much light at night. My friend loves the idea. I don't know if there is enough demand for this. What do y'all think of this idea? You can also roast it. Any feedback would be appreciated. Cheers :)

Hi guys! My name is Raph. I've been deep into biohacking for about six years — cold plunge, fasting, meditation, the whole stack. Somewhere along the way I fell down the circadian science rabbit hole and haven't come back up.

One thing that bugs me: almost every blue-light blocking glass out there treats everyone the same. Same orange tint, same fixed filter, whether it's 2pm or 10pm, whether you spent the day outside or in a windowless office. Your eyes got completely different light exposure in those two scenarios, but the glasses don't care. Indoor office lighting gives you roughly 50-100x less circadian-effective light than being outside on an overcast day — so someone who worked outdoors all morning has a totally different need in the evening than someone who sat under fluorescents for 10 hours.

I used to wear blue light blockers. Most nights they make me feel tired way too early, like they're overcorrecting. Also, some nights I want to continue to work at night but minimize the disruption of the lights. I started wondering if the problem isn't blue-light blocking itself, but that it's completely one-size-fits-all.

I've been researching whether a more personalized approach to managing light exposure could actually work — something that tracks how much light you actually get during the day and blocks blue light gradually, adapting to the environment and your sleep schedule. But I genuinely don't know if people would wear something like that daily, or if fixed-tint glasses are "good enough" for most people.

A few questions for anyone who's tried to manage their light exposure:

1. Do you actually think about your light exposure during the day, or only when you're trying to fall asleep?
2. If you use blue-light glasses — what made you start, and what annoys you about them?
3. For anyone doing shift work — how are you handling the light side of things?
4. Would you want something that adapts to your actual day, or is putting on orange glasses at 8pm fine?

I keep coming back to this idea but haven't committed to building anything. I come from a UX/UI design background, not optometry or sleep science, so I'm trying to figure out if this is a real problem or just my problem. Honest "I'd never care about this" is just as useful as anything else.

Hi, I'm Raph. Six years into biohacking (cold plunge, fasting, meditation) and at some point I got pulled into circadian science. One thing kept bugging me: half the people in this sub say blue-light glasses changed their sleep, the other half say they're useless. Both camps have reasonable points. So what gives?

After months of reading papers and threads, I think the variable nobody talks about is what happened before you put the glasses on.

Research shows that people who get strong light during the day become less sensitive to blue light at night. Their circadian rhythm is already well-anchored, and their melatonin rises on its own in the evening without needing help. Throw 99% amber blockers on top of that and you're overcorrecting a system that was already winding down fine. That's the 8pm crash.

Now flip it. Someone who sat under dim fluorescents all day is actually more sensitive to evening blue light, so you'd think the glasses would help them the most. But the bigger problem is that their body never got a strong daytime signal. The whole rhythm is flat. The glasses address the nighttime end, but the root cause is what happened (or didn't happen) during the day. That's why the effect feels inconsistent or weak.

Same glasses, opposite experience. Not because the glasses are broken, but because they can't account for what your day looked like. I wore blue blockers for a while. Some nights I'd be completely done by 8pm when I still needed to work. Other nights, zero effect. It didn't click until I started paying attention to how much daylight I was actually getting. The glasses weren't the variable. My daytime light exposure was.

That's what got me wondering: what if glasses could track your light exposure throughout the day and filter gradually based on what you actually got and sleep schedule, instead of always blocking the same amount at the same time? I genuinely don't know if anyone besides me would care enough to wear something like that daily, which is why I'm asking here.

For anyone who's dealt with this:

1. Do you pay attention to your light exposure during the day, or do you only think about it around bedtime?
2. If you've used blue-light glasses, were the results consistent or all over the place? Any idea what made the difference?
3. Anyone on shift work: what are you doing about light management right now?
4. Would you want glasses that adjust based on your actual day, or is throwing on orange lenses at 8pm working fine?

My background is UX/UI design, not optometry or sleep science. I'm trying to figure out if this is a real gap or something I talked myself into. "I'd never care about this" is a completely valid answer.

I'm currently building a neurotech hardware startup in Shenzhen. We are building a 10 min mental reset button that replace 2-3 hours of sleep. I'm looking to find cognitively demanding, busy, high performing professional to interview. I DMed 300 people on Linkedin last month. The response rate is 5%.

Any tips or tricks to share? Appreciate you!

Hey guys,

I'm tinkering with a hardware idea and I want some brutal honesty before I sink money into prototyping it.

I love float tanks and meditation, but booking a tank is expensive and a hassle. I was looking for a way to replicate that deep sensory reset at home.

The idea: A neck/body floaty that has built-in bone conduction speakers designed specifically for audio entrainment (AVE/binaural beats). Because sound travels incredibly well through water and bone, it basically turns a normal pool or bathtub into a highly immersive meditation tank. It bypasses waterproof earbuds completely (which I hate because they never stay sealed).

You get the weightlessness of the water paired with the brainwave sync of the audio.

Would you actually buy something like this for recovery/relaxation? Is it too gimmicky? Tear the idea apart, I want to hear the downsides.
