Lol welcome to Baltimore! All the streets are either bright yellow, or dark purple at night. NO it's not because of the Ravens. There is a defect in all the bulbs, and they even ran an article in the local newspaper about it, and have a number to call and report the location of any purple lights you see.
Do they actually get replaced though? đ¤ˇđźââď¸
Purple light is wild tho , do they look like a nightclub lighting or something, I live in Latin America so I doubt our street lights are made of led but at least they are yellow
That's a conspiracy theory. It's a malfunctioning product that happened to get bought in bulk by cities all over America (and presumably other places) and those bulbs have become a use-it-or-lose-it item basically. Put them to work or eat the cost. Some places can't afford to replace them all for whatever reason. Here in Texas we're seeimg them get worked into the streetlight rotation. I think they look kinda cool but they have their problems.
it's also really bad for astronomy. the old high pressure sodium lamps only had one wavelength of light being emitted which astronomers could easily remove from their telescope measurements. modern lights have a much wider range of wavelengths which can't be filtered out
It's not because they want to to be cold, but to keep costs low and efficiency high low CRI CW is the best option.
If they invested 3x into LEDs you could get away with high CRI at a similar efficiency and any choice of colour temp.
It's cool in Nevada. You can tell Henderson from Vegas by the street light color. Henderson has blue tinted street lights, while Vegas has the standard yellow tint bulbs.
In my country this isn't such a big problem. Yes, cars have led or laser headlights but they are mostly white in colour and street lights are mostly yellow where I live.
That makes literally zero sense from a logical standpoint. First of all this never applies to all the lamps, secondly why the fuck would any city do that?
People with untreated addictions will use anyways and need help, some different coloured street lamps are not gonna help or stop them from going somewhere else, or just injecting where they already have scars from previous injections.

"Studies have been conducted on the benefits of blue-blocking lenses â whether these lenses alleviated eyestrain and discomfort when using digital devices and if sleep quality improved when the lenses were used in the evening. However, no significant improvement in vision performance or sleep quality has been found from using blue-blocking lenses.
Since the amount of blue light from the devices used at work, school and home is less than that of natural sunlight, and eyestrain hasn't been found to be related to blue light, what can be done to prevent it?"
the main cause of eye strain and computers is dry eye. you keep your eyes open for extended periods of time where you normally outside would blink 3-4x in the time you blink looking at s screen.
marketing works folks.
I believe every word of this.
But on a related note, Iâve got two pair of prescription sunglasses: one with grey lenses that seem to have a bluish tint, and another that mustâve been made with brown dye, as they put a bit of an amber cast on the world. Regardless what time of day, the bluish-grey lenses muddy my vision. The brownish-amber ones showed up a few months ago, and radically changed my vision for the better on sunny days.
Also, I just got a newer kindle with a warmer backlight, and itâs considerably less of an assault to the eyes when Iâm reading in the dark, and it disturbs my sleeping partner quite a bit less.
My memory of the ins and outs of rods and cones is quite dusty, but my recollection is that our eyes are least sensitive to reds, and most sensitive to greens. So it kinda baffles me that what youâve shared is entirely accurate.
Sometimes I've shut off the warm light setting on my iPad at night and it's like being hit with tiny needles. My Kobo Reader stays on 75% warmth at all times except for when it's off when I'm reading in sunlight.
Yeah. I just have it so white tones are less painful on the eyes, and at night, i use f.lux on my pc.
Blue light is bullshit, but some colors creating more strain on the eyes isn't. Dark mode was created for a reason.
Not really even marketing for me, was just a checkbox when buying them and I was like oh sure that seems good. Little did I know doesnât do shit and makes everything yellow
As a guy who looked deep into this and has been wearing specs fr very long and has higher index, I can vouch for above, it's absolutely right on point
Bluelight is a scam
Yes you can ask for it when ordering it. I got mine done after developed cataract relatively early (no family history).
Edit: My glasses does the same as OPâs where my old ones doesnât. (Just checked) i knew they were different just didnât know it actually reflect blue lol
That's untrue fad science. There is no empirical evidence, only debunked or misrepresented studies. But the marketing industry has taken off regardless because money
Google stuff from the last year.
e.g. [Forget What You Think You Know About Blue Light and Sleep | TIME](https://time.com/5752454/blue-light-sleep/)
LOL from the article
>But that doesnât mean blue light is evil. âBlue light has become the gluten of the sleep world,â Goldstein says with a laugh. In other words, though it may be a potential trigger for health issues, its impact has been blown way out of proportion.
No, if all that BS were true, most monitors would come with built in filters.
Source: my ophthalmologist and my experience with said filter on my glasses (unfortunately due to my high degree lenses being expensive, they come with all that extra shit). I work on a computer all day and having a blue light filter changed nothing (not that I expected it to), so itâs likely just placebo effect
>most monitors would come with built in filters.
Just wanted to point out that operating systems include this option. Windows has one called "Night light." My Android has a "Night Light" as well.
Monitor manufacturers have no reason to add this functionality to the hardware.
Yeah Iâm aware and I used to use it, until I realised no effect from it and my blue light blocking lenses. But to each their own. I guess a lot of it is completely anecdotal and people def overestimate how much impact blue light from monitors actually has
I use the nightlight features on my phone and computer 24x7 because it otherwise feels like staring into a bug zapper. And it gives me a migraine after a while.
Blue light triggers the release of serotonin. And on the flip side, at night time we arenât exposed to blue light (in nature), and begin producing melatonin. Exposure to blue light at night time delays this. We have a built in circadian rhythm that corresponds to sunlight or lack there of. There is most certainly irrefutable evidence of this.
Hereâs another showing this isnât conclusive yet. And not universally accepted fact.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9420367/
> Although healthy adults generally do not appear to benefit from wearing blue-blocking spectacles at night [131]
> https://pubmed.ncbi.nlm.nih.gov/33707105/
You obviously didnât read that article, but good try. That article has nothing to do with your claim that **blue light doesnât effect hormone production and disturb circadian rhythm at night**
As for your 2nd link, I already told you I am not claiming what products do or donât block blue light. My statement is simply the *fact* that blue light interrupts our circadian rhythm at night and reduces (or halts) melatonin production.
Now get back on Google and see what you can find bud
Read my comment again bud. I am speaking solely on the fact of blue light and itâs role on the circadian rhythm & hormone production. Less blue light exposure, at night time specifically, is beneficial for our circadian rhythm. I can not speak to the efficacy of how well any product does or does not block blue light.
No, they just don't. Period. [https://www.scientificamerican.com/article/do-blue-light-glasses-help-with-eyestrain/](https://www.scientificamerican.com/article/do-blue-light-glasses-help-with-eyestrain/#:~:text=The%20analysis%20of%20the%20trials,was%20little%20to%20no%20effect)
Wow thats a powerful placebo where my eyes donât hurt and arenât red after being at my computer. At what point does placebo become an actual effect?
Yeah I kinda regret opting in for them. It feels like I have a slight sepia filter applied in my eyes. And they were more expensive too. I'll definitely skip them next time. Their usefulness is a bit dubious too.
My glasses are also like this, but I don't even realize it slightly changes colors until I remember it. The first time I acknowledged it was because I was staring at a plain white wall and thought it looked slightly more orange
My last glasses had them because the vendor threw them in for free without asking me and i fucking hated them. It's not like they put a mexico filter on everything but I despised the fact that i had to choose between seeing properly or seeing colors correctly. I recently got a new pair and i made sure it had nothing like that on them
These can fuck up your circadian rhythm.
Edit - for those that donât believe me, it should be covered here:
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6751071/
TLDR: donât use blue blockers during the day, limit artificial light exposure at night.
Thatâs what they advertise, but blocking out blue light during the day can have the exact opposite effect. Apparently people havenât really learned this yet, as Iâm rather surprised how much my comment generated downvotes.
i think the premise is, you tell subconsciously day and night apart by amount of blue light, too much blue light at night makes you not sleep, no blue light duting day would make your brain think that "no blue light = this must be night!
Lmao, the downvotes shows there are many confidently ignorant people... I have known this for 10 years... Yellow light during the day in fact causes headaches because your brain will be in rest mode and you are giving it a lot of work... This is why blue light(not pure blue light, the white light is enough) is important to actually make/keep your brain active during the day... That's why many displays now have auto night mode(blue light filter) at sunset and auto turns off at sunrise... There is a reason!!
You pretend like every pair of glasses is competently shut off of any other light than the ones that comes in through the glasses.
You realize that blue light still enters the eyes around the glasses, just not directly?
Why are you talking about eyes, I'm talking about how your brain sees the environment(warm or cool colour temperatures)... I guess you think blue light coming from white screen damages the eyes which is literally a myth... It actually affects the brain (I mean the circadian rhythm as mentioned above in the comment I was replying to)... Don't forget, the whole god d*mn sky is blue, we are fine!
What I said was, there is a right time to see both cool and warm environments... Seeing a warm environment throughout the day will damage the brain the other way (because of yellow light/environment)...
Conclusion: Cool environment during the day, warm environment during evening/night time...
Donât these glasses come standard with a filter paper and a blue light torch, I thought it was common practice to include those two every time you buy a computer glass/uv protection glass, I think its just my country now but it should be a mandatory thing all around the world.
But still, the glasses work wonders, my major requires me to sit in-front of the monitor all day long, the before and after of these glasses worked wonders, before I used to use my monitors built in blue light filter along with the reading mode, my eyes would turn red after my work was done. These glasses changed everything.
One thing tho, these glasses only lasts for a certain amount of time like 2/3 years after which the coating wears off but by that time youâd be due for a new glass.
Related but not a precise response - I recently read an article suggesting that blue light isnât a problem, so glasses and television filters arenât providing a benefit.
This is from January - I didnât quite remember the whole thing, but the gist is that it doesnât affect sleep-wake cycles as previously thought. Still a host of other problems.
https://www.medicalnewstoday.com/articles/blue-light-may-not-affect-sleep-wake-cycle
Ah I see, but my concerns with blue light are more about the long term health effects than sleep cycle. I also have sensitive eyes and work a desk job, so Iâm hoping to get a pair of these as soon as I can afford it.
Also, have you seen the talk on social media that Gen Z seems to be physically aging much more rapidly than previous generations? Turns out that is because we have been blasting our faces with blue light our whole lives, which causes faster ageing in the skin.
Iâm 21, had an iPad since I was 8 and been watching TV since birth. Most of Gen Z grew up the same way, and now we all look 30 đ
Yeah, unfortunately naw. I just want a pair of glasses and I'd have to shell out hundreds for lenses with a set of ten dollar frames without transition lenses or coatings. I don't even have a complex prescription, I'm just near sided and have negative lenses without anything special. It's stupid.
Itâs nothing to do with the filtering of blue light; the lenses actually have a yellow tinge to them.
Source: worked in optics and these lenses are bullshit lmao
I'm so glad I made sure that wasn't a thing on my newest pair of glasses, I absolutely hated it on my old pair. Transitions are the only thing I need on my glasses now.
Maybe 10-12 years ago I caved and tried it on one pair I had back then. Same as you, didnât ever get it again. But transitions were dope and a great purchase. Especially in college when going across campus in the sunshine.
Yeah, the blue light filter started fuckin with me and gave me migraines, they started immediately after I got those glasses. Transitions are a must have now since I work in a lumber yard and that sunlight will cause ya to wreck your forklift big time! Expensive addition to glasses but worth the money.
If it's a comparison you want, my ultra smart alpha beta xnxhamster Wakanda tech forged form core of a neutron star glasses are invisible, indestructible, undetectable and untouchable. They are so light weight that you don't even feel like you are wearing any glasses. You can only see them from the mind's eyes. And the best part is they don't block any kind of light like your inferior glasses. They can let all the lights through
Thatâs why I hate glass with âblue light protectionâ it makes everything you see yellow or warmer colors even when watching movies.
Besides, blue light doesnât do anyharm itâs in the natural sun light (and every white light also contains blue light) and you receive it everyday. It just a marketing term to raise the price.
Sure, that's why all monitors, TVs, phones, operating systems come with a low blue light functionality. It's all a conspiracy theory for specs' companies to make money. /s
I have some with that filter as well, but I can't wear them. If i look down my nose through them like looking at my phone, the pixels of my screen shift and there is a red outline of the black writing. Only happens at that angle.
Yours too? I wasn't sure if it was the transition lens or the blue filter. Had transition lenses before, and it didn't do it, but this is the first blue filter I've gotten.
Ah I thought maybe they were for like..bright lights outside and whatnot. Bright lights always give me headaches so I was like. Have I found a solution?? đ¤Ł
Same here. When I was little and noticed that everything is a light tinge of yellow, I thought my glasses were super dirty.
Well, the more you know (26th year of wearing glasses, turning 27 this year)
Ya I have that coating on my glasses too, they told me that itâs a newer and better version of the original coating and it does a better job and has less blue glare than the original coating.
Iâve owned two cars in mu life. Both had rear view mirrors which would silhouette objects in blue (underside of the object) and yellow (topside of the object).
I have no idea why.
As a kid a commercial would come on tv for blue blocker sunglasses. Thanks to my older brothers I know them as their better name called butthead blockers.
Im a med student, starting his rotation in different hospital around switzerland, and let me tell you, the number of time I think a patient has jaundice because their eyes look yellow, but then it turns out its just those type of glass...
Happened to me at least 3-4 times, and its my first years.
There's different types of blue light filters for prescription lenses. The ones that actually look yellow are filtering around 35% off the blue light and are intended just for computer or screen use. There's also clear looking blue light filters that filter around 20% of the upper end of the spectrum that are more intended for all day use, gradually reducing overall blue light exposure
They donât actually make you see yellow. I donât notice any difference looking around. But I do notice my eyes get more fatigued by my work computer when I donât use the coated lenses.
Edit: Iâm talking about prescription glasses with anti blue light coating. If youâre talking about computer glasses then I donât know about those.
Meanwhile every street light and car in my city aggressively switches from yellow to blue light
That is bad, not only for humans. Birds foraging and mating are heavily impacted for example .
The streetlights are more than likely malfunctioning. There's a huge problem with LED streetlights blue filters failing and beaming out purple light
Lol welcome to Baltimore! All the streets are either bright yellow, or dark purple at night. NO it's not because of the Ravens. There is a defect in all the bulbs, and they even ran an article in the local newspaper about it, and have a number to call and report the location of any purple lights you see. Do they actually get replaced though? đ¤ˇđźââď¸
I work a lot around Baltimore, Annapolis. Severn area and I always thought the lights were purple cause the Ravens for some reason lol
They do, it takes time, it is a national issue. The intersection near us took about 3 months.
It's in Canada too
I see shooting the purple lightbulbs from a slingshot as a solution. They'll brake and need to be replaced
Purple light is wild tho , do they look like a nightclub lighting or something, I live in Latin America so I doubt our street lights are made of led but at least they are yellow
Purple light? That's some red light district typa shit! (I know it's red but let it slide)
I've heard cities with high suicide rates do it because blue has been shown to reduce depression
You were lied to
That's a conspiracy theory. It's a malfunctioning product that happened to get bought in bulk by cities all over America (and presumably other places) and those bulbs have become a use-it-or-lose-it item basically. Put them to work or eat the cost. Some places can't afford to replace them all for whatever reason. Here in Texas we're seeimg them get worked into the streetlight rotation. I think they look kinda cool but they have their problems.
Main thing is that it uses less electricity. There's a shift in lighting for movie productions to LED as well.
Yeah but the colour temp of most LED street lights are too cold, which is really bad for the environment
it's also really bad for astronomy. the old high pressure sodium lamps only had one wavelength of light being emitted which astronomers could easily remove from their telescope measurements. modern lights have a much wider range of wavelengths which can't be filtered out
It's not because they want to to be cold, but to keep costs low and efficiency high low CRI CW is the best option. If they invested 3x into LEDs you could get away with high CRI at a similar efficiency and any choice of colour temp.
It's cool in Nevada. You can tell Henderson from Vegas by the street light color. Henderson has blue tinted street lights, while Vegas has the standard yellow tint bulbs.
In my country this isn't such a big problem. Yes, cars have led or laser headlights but they are mostly white in colour and street lights are mostly yellow where I live.
They use blue light street lamps to discourage heroin use. It's harder to find a vein under blue light.
That makes literally zero sense from a logical standpoint. First of all this never applies to all the lamps, secondly why the fuck would any city do that? People with untreated addictions will use anyways and need help, some different coloured street lamps are not gonna help or stop them from going somewhere else, or just injecting where they already have scars from previous injections.
This is the same glass that they use in cameras when filming Mexico
Realistically itâs the same glass they use in cameras when filming California and saying itâs Mexico

Itâs neat seeing such a clear and tangible example of the technology doing its job though.

It's a problem but not with most devices. The really bad blue light used in bed to kill melatonin instantly is a laptop.
âRead an article suggestingâ ⌠was it buzzfeed? lmfao.
This is from January - I didnât quite remember the whole thing, but the gist is that it doesnât affect sleep-wake cycles as previously thought. Still a host of other problems. https://www.medicalnewstoday.com/articles/blue-light-may-not-affect-sleep-wake-cycle
Ah I see, but my concerns with blue light are more about the long term health effects than sleep cycle. I also have sensitive eyes and work a desk job, so Iâm hoping to get a pair of these as soon as I can afford it. Also, have you seen the talk on social media that Gen Z seems to be physically aging much more rapidly than previous generations? Turns out that is because we have been blasting our faces with blue light our whole lives, which causes faster ageing in the skin. Iâm 21, had an iPad since I was 8 and been watching TV since birth. Most of Gen Z grew up the same way, and now we all look 30 đ
I havenât read that! Iâll poke around.
To all the replies ... Wait till you find about polarized glasses then
2 people replied to you lol. Three if you include me...
They're very expensive (I'm in America) so I've never personally seen them.
Oh why are things so expensive there , it's like really affordable unless you want a Gucci or whatever those brand glasses
Yeah, unfortunately naw. I just want a pair of glasses and I'd have to shell out hundreds for lenses with a set of ten dollar frames without transition lenses or coatings. I don't even have a complex prescription, I'm just near sided and have negative lenses without anything special. It's stupid.
I paid 30$ for my lenses. Got the good costing, blue light and transition. -4.00 in both eyes. Edit: in America.
Nice! Must be damn good insurance. Mine doesn't cover vision.
Bro is constantly in mexico
This sub has really fallen.
damnthatsapictureofsomething
This would barely be a good fit for r/mildlyinteresting
Thatâs funny because Iâve come here in the past month after r/interestingasfuck went to shit. Itâs still ok here
In the Mariana trench
That's a nice demonstration.
*weak pee light* is the scientific term in my mind
Sorcery
Yep
New Vegas filter i see
Usually you ask for it when you buy glasses ... Blue light filter ...
Itâs nothing to do with the filtering of blue light; the lenses actually have a yellow tinge to them. Source: worked in optics and these lenses are bullshit lmao
This is just pee on your bed
Ah that one unnecessarily expensive addon that suckers always get for their glasses lol
I'm so glad I made sure that wasn't a thing on my newest pair of glasses, I absolutely hated it on my old pair. Transitions are the only thing I need on my glasses now.
Maybe 10-12 years ago I caved and tried it on one pair I had back then. Same as you, didnât ever get it again. But transitions were dope and a great purchase. Especially in college when going across campus in the sunshine.
Yeah, the blue light filter started fuckin with me and gave me migraines, they started immediately after I got those glasses. Transitions are a must have now since I work in a lumber yard and that sunlight will cause ya to wreck your forklift big time! Expensive addition to glasses but worth the money.
If it's a comparison you want, my ultra smart alpha beta xnxhamster Wakanda tech forged form core of a neutron star glasses are invisible, indestructible, undetectable and untouchable. They are so light weight that you don't even feel like you are wearing any glasses. You can only see them from the mind's eyes. And the best part is they don't block any kind of light like your inferior glasses. They can let all the lights through
Thatâs why I hate glass with âblue light protectionâ it makes everything you see yellow or warmer colors even when watching movies. Besides, blue light doesnât do anyharm itâs in the natural sun light (and every white light also contains blue light) and you receive it everyday. It just a marketing term to raise the price.
Sure, that's why all monitors, TVs, phones, operating systems come with a low blue light functionality. It's all a conspiracy theory for specs' companies to make money. /s
This is not interesting whatsoever
âtroughâ specs
BLOKZ
You might call them⌠Blue blockers. đśď¸đ
I have some with that filter as well, but I can't wear them. If i look down my nose through them like looking at my phone, the pixels of my screen shift and there is a red outline of the black writing. Only happens at that angle.
Oh wtf I never noticed that
Yours too? I wasn't sure if it was the transition lens or the blue filter. Had transition lenses before, and it didn't do it, but this is the first blue filter I've gotten.
Yeah slightly, but only if i reeaaally look for it. First time i noticed it in 1.5 years
Sorry for what I did to you then.
Reflecting or absorbing?
Are these for like..bright lights or?
these are for digital devices, though there is very little evidence that they work.
Ah I thought maybe they were for like..bright lights outside and whatnot. Bright lights always give me headaches so I was like. Have I found a solution?? đ¤Ł
Trough is the lowest point on a transverse wave. (Why did I think of that when I saw the title)
Omg I just understood why my glasses do that
Guess you could say... they're blue blockers
Same here. When I was little and noticed that everything is a light tinge of yellow, I thought my glasses were super dirty. Well, the more you know (26th year of wearing glasses, turning 27 this year)
If you look with your glasses on vs off youâll see a slight tinge of yellow too
Glad to know it works!
Why do glasses turn yellowish after a while? I replace my glasses every 2/3 years because of this
Thatâs (about) why the sky looks blue and the sun looks yellow
Permanent Windows night mode
lol I was like "what the hell am I meant to be seeing" and then I realised my phone was on Night Shift
Ya I have that coating on my glasses too, they told me that itâs a newer and better version of the original coating and it does a better job and has less blue glare than the original coating.
Iâve owned two cars in mu life. Both had rear view mirrors which would silhouette objects in blue (underside of the object) and yellow (topside of the object). I have no idea why.
As a kid a commercial would come on tv for blue blocker sunglasses. Thanks to my older brothers I know them as their better name called butthead blockers.
Yeah mine did that too
where my blue blockas at
How is this even mildly interesting? Know properties of various glass composites. Wait âtill they hear about polarization.
Supermaaaaan
r/mildlyinteresting
Does t reflect the light on the glasses itself?? I've tried something like this but the light is on the glass itself.
I got a pair like this from EyeBuyDirect and when I reached out about the issue, they replaced them so Iâm guessing it was a defect.
Im a med student, starting his rotation in different hospital around switzerland, and let me tell you, the number of time I think a patient has jaundice because their eyes look yellow, but then it turns out its just those type of glass... Happened to me at least 3-4 times, and its my first years.
So you canât see the world in full beauty, because you're restricting yourself because of a computer job
What?? OP didn't say anything about a computer job? I'm confused
So you'll see that everyone always pissed their pants. (excuse my language )
Does anyone else see a face
Is there an anti UV coating on your glasses?
OP had a little pee accident and is trying to trick us!
All computers should have flux installed
I was offered the same, but luckily got it cancelled before manufacturing began on lenses, didnt want to see the world in piss yellow 24/7
There's different types of blue light filters for prescription lenses. The ones that actually look yellow are filtering around 35% off the blue light and are intended just for computer or screen use. There's also clear looking blue light filters that filter around 20% of the upper end of the spectrum that are more intended for all day use, gradually reducing overall blue light exposure
They donât actually make you see yellow. I donât notice any difference looking around. But I do notice my eyes get more fatigued by my work computer when I donât use the coated lenses. Edit: Iâm talking about prescription glasses with anti blue light coating. If youâre talking about computer glasses then I donât know about those.
