I bought these for 20$

This guy actually tested these in case you wanted some sort of verification 🤟🏼
Im an optometrist
They’re all a retarded scam
The problem isn’t blue light, the problem is your phone
Grow up and control your ability to use your phone before bed instead of buying this scammy crap lol
"While light of any kind can suppress the secretion of melatonin, blue light at night does so more powerfully. Harvard researchers and their colleagues conducted an experiment comparing the effects of 6.5 hours of exposure to blue light to exposure to green light of comparable brightness. The blue light suppressed melatonin for about twice as long as the green light and shifted circadian rhythms by twice as much (3 hours vs. 1.5 hours).
In another study of blue light, researchers at the University of Toronto compared the melatonin levels of people exposed to bright indoor light who were wearing blue-light–blocking goggles to people exposed to regular dim light without wearing goggles. The fact that the levels of the hormone were about the same in the two groups strengthens the hypothesis that blue light is a potent suppressor of melatonin. It also suggests that shift workers and night owls could perhaps protect themselves if they wore eyewear that blocks blue light."
There are so many variables at play
These are low level experiments
None of them are blinded nor repeated on a large scale
There’s so many things you could justify with low level testing as such
How do you not know in the first study that it’s in fact green light that improves your circadian rhythm?
Also the fact people in the second study weren’t wearing glasses induces a placebo effect.
“The fact the levels of hormone were about the same” - what does that even mean? How is the hormone of a group measured ? Are they roughly the same age and if so, that doesn’t mean they’ve the same level of hormones
99% of research nowadays is incredibly poor. Researchers are incentivised to get valid results to get more funding…there’s never been a good study on blue light and I doubt it’s even possible to carry out in the world we live in today
Yeah but loads of folks on YouTube say it’s a thing.
I don't watch podcasts, I used a friend's pair in the gym bc the lighting there is fucking horrible & it immediately struck a nerve with me.
Especially since I use dim lighting & candles at home.
I feel you on the studies, there's definitely more to be done there.
I'm using my intuition here.
When I'm around dim lighting or even better situations when I have a stockpile of beeswax candles I fall asleep faster.
Further, if you look at the light spectrum a candle gives off versus led light bulbs or your phone / TV / computer screen you see the dicotomy quite clearly.
Lastly, increasing intensity light waves have been proven to increase cognitive function & alertness - that's not even up for discussion & obvious to anyone who has dimmers.
Conclusion: blocking light waves from entering the eyes when the sun goes down seems like a promising intervention to aid in drowsiness.
I will be trying this myself using a 20$ pair that has been proven to block blue & green light waves - mimicking candle light.
No one uses phone / TV / computer screen for its light though, there’s a compounding factor that they make people restless because they’re also relaying mentally stimulating information
I think the candlelight is a great idea ~ natural and all it does is provide light. Nothing else. No mental stimulation in the form of information from a TV or phone
If you watch enough marketing videos I’m sure the glasses will work ~ i wish you the best
You don't use lightbulbs after sunset in your house?
Or your phone?
The mentally stimulating part is definitely part of it, but not all of it.
There's also the question of how bright the screen and proximity to your face - versus ambient lighting.
Your pineal gland is definitely affected by light, just close your eyes and shine a flashlight right at your "3rd eye".
I haven't watched a single video on this btw, just used my friend's in the gym and was intrigued.
For 20$ I'm going to conduct the experiment myself.
If it improves my sleep schedule I win.
If it doesn't it costed me nothing basically.
I never said I didn’t
I recommend not but I’m a human being and as such, I do
I think candles are the actual solution to people’s problems - the ideal solution to this problem we’re discussing
I don’t think much else matters when talking about blue light and blue blockers specifically
You’re rambling into other things now like how we can detect light when our eyes are closed so I’m happy to leave it at this
