Blue/green light blocking glasses

[ThunderBird]

Anyone have recommendations for blue light and green light blocking glasses. Recently got interested in them but to me they all look like glasses with red lenses haha. Also if anyone can vouch for the efficacy and that the concept of blocking that is real and noticeable I would also like to hear about that.

I’m good with alibaba Amazon whatever just looking for the good stuff also trying to keep it around 100 bucks

Aside from helping get sleepy, I don’t reckon they’re overly effective at much.

My screens have night shift to reduce blue output in the relevant hours.

I have both of these. Really like the fit of the 1st ones but the 2nd ones are supposed to work better.

There's no clinical benefit to blue light glasses.

There's no clinical benefit to blue light glasses.

not sure where you are reading this or getting this info but there is a crap pile of papers written on blue light / green light and melatonin suppression. Also that is a extremely broad statement with not a single cited source haha.

Here you go Cochrane systematic review of 17 randomised controlled trials that recruited 619 people. https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD013244.pub2/full
Enjoy, haha

I haven’t read all of it yet but I came back here to say that it specifically says that people in these trials reported better sleep. Also it aknowlages that it has no idea what type of glasses any of these studies are using. Also you can just cherry pick whatever you want in these. I am still reading through to so I may be convinced otherwise but I can’t access like half of the studies in this thing.

Frontiers | The influence of blue light on sleep, performance and wellbeing in young adults: A systematic review

Introduction: Blue light from electronic devices has a bad reputation. It has a wavelength which may influence our circadian rhythm and cause bad sleep. But ...

This systematic review says basically the same thing that the research is a mixed bag, I do appreciate you trying to support what you are saying though. But it doesn’t at all add to what I’m looking for. Which would be a recommendation for blue/green light filtering glasses.

It’s effective at lightening your wallet. Some people report improved sleep but you could also cut screen times before bed if that’s your goal.

I'm sorry but you obviously have little or no experience of research papers. There is no cherry picking this is a Cochrane review which is the highest regarded evidence base.
To summarise for you :
The review found that blue-light filtering spectacles did not perform any better that non-blue-light filtering spectacles in reducing eye strain associated with computer use, had little or no effect on best corrected visual acuity and an inconclusive effect on sleep quality.

The high quality study found the following key findings:

• There may be no short-term advantages with using blue-light filtering lenses to reduce visual fatigue with computer use, compared to non-blue-light filtering lenses
• There is limited information about the potential effect(s) of blue-light filtering lenses on visual acuity and the effects on sleep-related measures are unclear
• Adverse events related to blue-light filtering lenses were infrequently reported, but included increased depressive symptoms, headache, discomfort wearing the glasses and lower mood.

But yes good luck in your quest to buy some anyway. However I was replying to your questioning of my statement that they have no clinical benefit.
Which they don't .

Thanks for your help, unfortunately this is still not what I’m looking for, also sorry if I upset you man. But you 100% can go through and cherry pick any research paper and interpret anything how you like. Also I don’t know why but every comment you leave I read in an old man British accent in my head and love it. Finally I’m not really on here to argue online with someone I was looking for recommendations.

But for the sake of arguing with others on the internet because it’s fun:

617 people in 17 trials is quite a small sample size. Those number make it sound big but that’s just not the case especially since this is all over the place in ages and countries the sample size is not big nor is it consistent. anyone who’s done research or taken a basic statistics class knows that. It’s not like you are chasing anything exceeding rare or dangerous in this the data set.

A majority of these studies did not focus or care about sleep. Which is what I’m focused on.

This systematic review says that they had no idea what glasses people were wearing. Which if you were trying to get good data would be the first thing you did and you would put a graph showing what wavelengths of light are filtered out that would be damning evidence.

The best conclusion you can draw from this if you actually read the paper which I’m sure you did and you drew you own informed conclusions. Would be the following: inconclusive at least in reference to sleep. The data is inconsistent and bad across the board. No fault of the paper there just isn’t enough good data.

Also no one cares what journal something is posted in, or a least shouldn’t care about that. While it may be a good start point to find reputable papers or sources the data is what matters not where it was posted if someone posted a full paper doing good science on Wikipedia it is just as valuable as being posted anywhere else.

Finally if this were to improve my sleep by 5% across a lifetime I personally would call it a win even if it was a placebo especially since it is such a small amount of money with 0 downsides. People on here buy and use things that very much could have massive downsides which ZERO evidence.

Also I hope you read my comments in a cowboy accent

Not upset, just trying to inform. Good luck in your hunt.
Go get 'em cowboy !

Yeah, that's Cochrane's goal, to uncover that.

I once came across a meta-analysis that stated that, out of 482 studies, only 5 were considered valid.

A recent review:

The only way to cut both colors is with ruby red. You won't know "for sure"(tm) until you have a spectral curve. You can test yourself with a $2 prism from AliExpress. At less than $20 a pair of glasses, they're worth a try.

Polarized glasses can significantly reduce the intensity too, but they aren't always properly aligned for screens.
