I'm keen to minimise my exposure to blue light in the evening although I am curious if these clear glasses actually make a difference.

Has anyone tried something similar and do they help with sleep?
 
In general, these claims about "blue light" seem a bit of a reach to me, and not as backed by evidence as they seem. What is tested is that bright lights, such as the sun or bright lamps with a high lumen rating, will alter your sleep schedule. If you want to help correct your sleep schedule then get exposed to bright light in the morning, the sun is best, and turn off as many lights as possible in the evening. Turn down the brightness on your screens to match. Glasses that filter out blue light will also reduce overall "lumens", but turning off/down lights and lowering brightness on screens is more obvious.
 
If you are already getting your extra 15 frames per second from your gamer chair:

And the extra 5 degree cooling from your gamer RGB oversized mousepad:

And you are using high end gamer headsets:

But are cautious of getting the gamer dent from prolonged usage:

Then why not purchase a set of gamer glasses to reduce the evil blue light that the illuminati use to spy on you and brainwash you:

yes it's a scam, just turn down your brightness at night.
 
I wear glasses, and this is an upsell any time you're getting new lenses frames. So while I don't have gamer glasses I do have it added to my regular perscription.

I can say, is there a difference? Sure. Is it worth getting something like this if you don't already wear corrective lenses? Probably not. But the upcharge is pretty insignificant when I get a new pair, so I go with it and have for the last several years. But I wouldn't wear them if I didn't have to either.

Yes, they help me. Glasses like these have been around for a while. Definitely not a scam.
 
My eye doctor talked about blue light with me because my eyes were hurting after a long day of work. She tested everything else and the blue light blockers helped a lot. I can tell a difference when I don't wear them. My eyes hurt at the end of the day if I don't have them on. I 100% believe it's a problem. All my glasses have the blue light blocking tint to them. I wouldn't get a prescription filled without it because I work around screens all week long.
 
Market Place why you don't need Blue Light blocking in glasses.

No evidence lenses are needed

Both Khurana and Garg told Marketplace there's no research that suggests blue light filtering lenses are necessary.

Phillip Yuhas, an assistant professor of optometry at Ohio State University, agrees. He said studies have shown people blink far less during computer use and that blue light filters have not shown any improved "visual comfort" for digital eye strain.

Khurana said if the problem people are having is from digital eyestrain, then blue light filters are doing nothing to address the core issue and "could be doing more harm than good."


blue-light-lens-still-3-jpg.jpg

Dr. John O'Hagan, an optical radiation expert who works for Public Health England, conducted a study into blue light and found that light levels from digital devices are 'not harmful' and 'considerably below the levels that we experience outside, even in winter.' (Pascal LeBlond/CBC)
But that hasn't stopped eyeglass retailers from promoting them. One optician told Marketplace the blue filter lens is like an "extra shield on top of your eyes to protect your eyes from harmful rays."

The lenses can be purchased with or without a prescription and range in price from $20 to more than $100.

Global sales of the lenses reached $18 million US in 2019, according to Marketwatch.com, and are projected to exceed $27 million US by 2024.

Free and simple solution

Staring at screens for a long time can make eyes feel dry, tired and strained, but blue light is not the culprit, said Garg, and purchasing special lenses won't fix the issue.

"What's bothering [people] isn't the blue light. It's the fact that when they're staring at their screen a lot they're not blinking as often.

"That causes the eye to dry out, [and] when your eyes become dry, they become irritated and scratchy and tired."

To deal with that, he recommends a simple fix. It's called "the 20-20-20 rule." Look at least 20 feet (six metres) away from your screen for 20 seconds every 20 minutes.

Blue light does wake us up and make us more alert, so too much late at night can make it hard to get to sleep. The American Academy of Ophthalmology recommends turning off devices or turning on blue light filters, a couple of hours before going to bed.

The 20-20-20 rule works better than blue light blockers, every 20 minutes look 20 feet away for 20 seconds.


Chances are if you have someone leaning on the blue light filtering then they've got vested interest in the blue light blocking coating.

I have real computer glasses from my optometrist that look like real glasses and not gaymer fewel and they're fantastic.
Very notable relief in eye strain since I'm working in front of a computer all day. I can go maybe one day of work before I realize I need to be wearing these things because I can feel the tension and strain the next morning.
I don't wear them when playing videogames.

And no they're not pay to win.

Blue blockers are mostly placebo effect from even professional sources.

Bias lighting is a great solution though if you're working/gaming in the dark, it's as simple as taking a light, putting it behind your monitor and pointing it at the wall behind it. Or as "complex" as getting a led light strip and putting it on the back of your tv/monitor. You're reducing the strain by creating a less harsh lighting environment for your eyes.

You should get better glasses or reading level, the article I posted from Market Place is 100% accurage, Market Place is a CBC product which get's it's funding from the Canadian Government, so it has no vested interests except for in the truth.

What you're getting is eyestrain, as I've already stated the 20-20-20 rule is a better counter to it than these silly blue coatings. You probably have Crizal Zen or whatever some other company shits out.

Professionals also have vested interests, especially if it's an optometrist, they'll get things for meeting sales goals on particular products.

If you're going to get a coating get Crizal Sapphire, it makes a nicer difference and you're lenses won't look like shit to the people looking at you.

Placebo is a helluva drug!
 
You can stop the blue light ghosts from getting you with the frequency red if you saw the movie. Just put some tape over your eyes when you are viewing a screen the color red and carry a role with you at all times.

It's blue light entering your eyes that causes your body to stop producing melatonin, the hormone that tells your brain whether the sun is up or down and therefore affects your circadian clock. You literally admit this in the next sentence with the sun, as that's where the most blue light comes from and why humans evolved to take advantage of it

Although a recent systematic review suggested that blue light-blocking glasses may help people with insomnia, Dr. Lockley says there's not enough detail about the studies to draw that conclusion. Most commercially available blue light-filtering glasses, and special coatings added to prescription lenses, aren't standardized. So you have no way of knowing which wavelengths are being blocked, and whether this affects only visual function, or important nonvisual functions such as alertness and the circadian clock. Also, the timing, duration, and nature of the nighttime light exposure in the summary of these studies was not clear.

If you want to block stimulating blue light that could interfere with sleep, avoid screen use as much as possible after dusk — especially within two to three hours of bedtime. You can also try using computer software that reduces the amount of blue light emitted. Examples include Night Shift (available on Apple devices) or f.lux, a free download available for all computers and related devices. You should also try to address other issues that affect your sleep.

When gunnars first came out I got a real pair of glasses with a dark yellow tint. I immediately noticed I slept worse when I didn't wear them before bed.

A decade later and now I make sure all my Zenni's have blu blocks. I still do wear the tinted glasses at night, I think they perform slightly better than the clears at night, but the clears no make my eyes not feel as dry during the day.
 
if you block blue light you logically can not have pure clear glasses... that's not how blocking light works. if you block blue then you will logically see less blue through them otherwise the blue wasn't blocked now was it?

Not a scam. I was thinking the same before but I've been wearing mine for work for 10 years now and my eyes are very thankful. It's a Gunnar brand.
 
If you wear prescription glasses with a blue filter treatment you can literally see the difference by removing them / putting them back, everything looks more yellow when you wear them.

So it does something for sure. And it feels more comfortable when looking at very bright screens.

You see, the problem with that dudes random video, is he doesn't know about blue light blocking effecting health.

Actual health professionals have weighed in and it's not doing appreciable difference in the blue light being blocked.

These fake gamer glasses are just adding tint to your vision, if you wore any cheap shit lightly tinted sunglasses while playing games, you'd get the same effect.

It's snake oil, but as I can see in this thread, some people love snake oil.

well I'm simply saying that clear blue light blocking glasses can not exist, in order to block blue light they need to be tinted. but there are completely clear ones which are a full scam as they don't block the blue wavelengths
 
Blue Light damaging eyes is as a scam.
Take regular breaks from your sceen, and use eyedrops if you temd do have dry eyes. Also try to avoid screens right before you go to bed.
You could also check your TV, phone and tablet for warmer colour tone settings. Often the devices are way too cool in colour temperature anyway to be comfortable.
Thats all there is to it.

Not a scam, but useful? Ehhhh.

They do block blue light and that's all they'll solidly claim if you look into it.

As for blue light actually affecting your health... that's really still up in the air. Well, the sleep stuff. The damage to your eyes stuff is bullshit.

I do have prescription glasses with blue light cutting ('free' upgrade). Honestly, they are annoying as they subtly make everything have a slight fringe to it.

Anecdotally, I can use screens right up until I go to bed and sleep like a rock. But hey, I could probably inject caffeine via IV and still sleep soundly.

If you really want to do it, then just install f.lux or an equivalent.

I don't wear glasses and I've had super blue light blocking lenses before which didn't do anything but fuck up colors, but whatever my optometrist gave me last time around actually worked.
I see an optometrist, now, in place of the opthalmologist, for my irregular nerve bundle and size. I also have collosal pupils which is super annoying at night

The thing is, these media scare stories about blue light lack evidence, and that means you should question them no matter if words like "harvard" and "doctor" are thrown around. Natural sunlight transmits way more energy from evil "blue light" than a computer screen, so why were our ancestors who spent most of their time outside not always awake, and even blind? Do you use, every day, a monitor which is brighter than the sun?

As for sleep schedule, where is the evidence that tests pure blue light against light without blue but with more overall lumens and says that pure blue light is more disruptive?

I wondered the same tbh, I do sleep better since using mine though (cheap ones from Amazon) and my eyes are less strained.

I used a multi-faceted approach mind you, to help me sleep. Valerian root to help with anxiety, one an hour or so before bed. Lights off an hour and a half before bed. No caffeine after 2pm. Regular exercise. Heck, I even changed my computer LED's to red light...Lastly (I may have forgotten a solution or two) I have some Lavender oil and spray bottle arriving soon, you mix the oil into a lot of water and spray it on your pillow at night, hopefully it helps!

Mostly it's important to not let your mind race when going to bed, just shut down those kind of thoughts and nip them in the bud, make yourself chill out and focus on good things, if you can do it without medication (as the side effects aren't worth it imo), then all the better!

Sweet dreams!

The body creates the hormone melatonin only when there isn't blue light entering the eyes. The body checks that hormone to figure out the time of day (no blue light = no sun). I don't understand what media scares you're referring to

Humans slept after sunset and woke after sunrise. Is that not obvious?

This just makes me feel grateful that pretty much all I need to do is lie down and I'm out in a couple of minutes if not immediately. Sometimes even just getting into bed (and invariably when I want to read/study/etc.) is enough for me to be out until the morning.

This just isn't true. The main source of melatonin is exposure to IR light from the sun. When it is dark, there is a trigger to release a certain amount to compensate for the lack of the main source from IR light from the sun. Blue light is only significant in that it is just one of the components of natural light which we detect as "missing" when it is dark, but lack of IR light is what is being compensated for.

Yeah, i was getting some new glasses a few month ago and they offered me that blue glass option. I was like wtf, get that shit out of my face. But then I tried it and the difference is huge. Never again without blue filter. It's a game changer, love my new glasses.
 
So far I use f.lux and I set it to 1900K when it's 8pm.

If this is sufficient as opposed to using glasses then that's good enough for me.

I don't get eye strain or tired eyes but it was specifically due to concerns that blue light suppresses melatonin and therefore disturbs sleep.

However IF blue light blockers actually filter blue light then that's good. Because I'd prefer that instead of making my screen look orange lol.
 
Do people not know monitors and laptops have settings...????????????? You can reduce the blue color or change your color scheme to a warmer one on pretty much any device. You dont need glasses lmfao unless everything around you not just the monitor/screens gives you a headache.

Intrinsically photosensitive retinal ganglion cells detect light on the blue spectrum at the highest rates (around 480nm) and when it doesn't detect enough of it, it sends a signal to the pineal gland to create melatonin. It doesn't to do that with other light spectrums because it isn't sensitive enough to them.

Here is a study done on retinal ganglion cells and how they affect the body's circadian response

I don't say it is wrong that light affects melatonin release.

Show me how.
1. The main source of Melatonin is not exposure to natural IR light from the sun.
2. Any "blue light oversensitivity" effect is greater than the wildly varying "lumens" we are exposed to, and why it is a bad idea to control overall bright lights when you can just filter blue.
3. Exposure to bright natural lights in the morning is significantly less important to sleep schedule than eliminating blue light at any hour.
4. How "unnatural blue light from screens" is causing permanent, irreversible retina damage.

It's anecdotal, but for more than a decade I wore very yellow clip-ons to combat eye-strain while working on computers all day. A couple of years ago I was offered blue light blocking coating or what have you on my new glasses lenses from Bailey Nelson (mall glasses chain) and I haven't needed to use the yellow clip-ons since. I still use a screen probably 12+ hours a day but no longer get bloodshot eyes or anything.

Could easily be a placebo or something, but I've personally had good success with clear "blue light blocking" lenses.

1. The sun is the main source of blue light, hence why our bodies evolved to take advantage of it to regulate our sleep
2. Are the bright lights you're referring to also filtering blue lights? Isn't it obvious that something like a flashlight contains both light in the blue spectrum and enough energy to heat up ganglion cells?
3. What do you mean by "bright natural lights", the entire point of what you're referncing is resetting our circadian rhythm. Which involves reducing blue light at night and allowing it to wake up. Which is why wakeup lights are recommended for people with irregular work hours.
4. Why are you asking me this? We're not talking about the UV range of light.

You keep using terms like "bright lights", but aren't referencing the lumens or spectrum to discuss.

You can only be so proactive/preventative before doing so becomes a problem itself.
