Dr. Jack Kruse: Blue-blocking glasses, and much much else

[jaybee]

Posted by RunningDeer (here)
[INDENT][INDENT]You're welcome, jaybee. Thanks for your in-put with the positive effects of blue blocking glasses.

There are a lot of things happening to effect our biology and the quality of life, but blocking out the toxic blue light is something we can change in a matter of days. And with a few behavioral changes, we also restore the dopamine imbalances which precipitate all kinds of addictions. (added below)

It's hard to know which blockers are effective and which are bogus. This post confirmed my personal experience with Amazon glasses: Not all Blue Light Blocking Glasses Are Created Equal, Which Blue Light Glasses Are The Best?

I mentioned earlier how I wasted money on a pair of cheapo blue block glasses from Amazon, which included a blue block test kit to prove they block the blue light. It wasn’t until my new glasses arrived that I discovered how true this statement is: “You get what you pay for. I had the new 100% blue blocking glasses on and couldn’t see the time on the digital clock because the numbers were blue.

{post snipped}

thanks again.... I did see what you said about 'you get what you pay for' ....

and, as with most things... this has to be true -

I decided to just get the cheap ones, that I can afford, for now... hoping they were better than nothing... and I think they are better than nothing - they claim to stop 99% of Blue Light and I'm wary of this claim but I can tell that a lot of Blue Light is stopped... whether some basic harmful frequencies of Blue Light are still getting through, I don't know -

cheers....

I agree, jaybee. Each and every choice moves us out of their way into our way. There are things we can do to change our lives, our environments now. Every change opens us. Things begin to click in ways we never were able to know or see. We rip off blinders of many levels through choice and action.

I soooo get the budget thing. Christmas is early. A lot of finagling went on over several months and a few more to come. It’s an investment in quality living. As mentioned, for most of my life, I’ve been good with right foods and exercise, but a restful night sleep was a distant third. This new found knowledge is priceless. My goal is to sleep through the night. I’m liking the challenge.

Cheers back to you.


While I’m here, I’ll add this for new comers to the thread:

Why are there other blue light glasses that are cheaper than BlockBlueLight's Sleep Glasses?

Many glasses that claim to be blue light blocking glasses on the market are just cheap glasses with an insufficient blue light reflective coating applied to them. These cheap glasses only filter anywhere from 5-15% of blue light. No science has gone into creation of blue light lens to ensure its blocking blue light in line with peer reviewed academic literature for sufficient protection.

BlockBlueLight's Blue Light Glasses are evidence based, science backed, and align with the academic research on blue light. We use a special pigment embedded into the lens which absorbs the blue light as it passes through (instead of just a basic reflective coating), this ensures our blue light lenses block 100% of all the blue and green light up to 550nm which is the exact wavelengths of light shown in the research to lower our melatonin levels and impact our sleep.

BlockBlueLight shows its lens reports for each lens on our website. Located under each individual product. No other company will show you their lens reports as they have something to hide, we do not and are happy to share these with you.

BlockBlueLight Glasses are also made with top quality acetate frames with spring hinges and top of the line optical grade CR-39 lenses . We are confident that you won't find better quality blue light blocking glasses on the market.

I've been using Gunnar brand glasses for 15+ years. They started as a Gaming glasses brand that specialized in blue light blocking & eye strain relief lenses.

This may vary from each persons Vision plan but mine covers a pair of Gunnars every few years. You do have to book an eye test with a company that sells Gunnar, which you can find a list of on Gunnars site & pay the co-pay.

If you're looking for a legitimate blue light blocking brand, Gunnar is one of them.

Cheers!

Dr. Kruse inspired me not to just use my near infrared sauna lights for saunas. I now have them in my main room plus use them for saunas. I have to move them back and forth from room to room but they're on a sturdy board with metal cages to protect the bulbs so not a problem. For winter I use them next to my wood stove in my sunroom for saunas. I like the way these lights feel: https://sauna.space/products/shower-...conversion-kit.

I've also eliminated LED light bulbs from my home and am replacing the incandescents with full spectrum bulbs: https://healthlighting.com/collectio...ndescent-bulbs

I use the 150 watt full spectrum bulbs for my living room/dining room area. I replaced my living room ceiling fixture with three 150 watt bulbs. It created too much heat so I had to keep the glass enclosure off. It feels like I have a mini-sun in my living room. So nice for dark fall/winter days.

Some bulbs such as in track lighting are difficult or now impossible to replace with incandescents or full spectrum bulbs so I'll eventually have to wire in new light fixtures in some rooms. Fortunately, I saw what was coming so I'd bought a lot of incandescents from Home Depot and now I see that they only offer LED lights.

Dear Bill, thanks for updating the thread title.

.........

If I’m not mistaken, Dr. Jack is wearing night-time red glasses during the day. The research on the Block Blue Light website makes sense.

EDIT TO ADD: Maybe it's night and the studio is all lit up? Jack suggests that if you've gotta go out with your buddies then wear glasses. I'd assume he means the yellow-day glasses because the red glasses at night makes you sleepy.

~ Don’t use night-time glasses during the day because it creates a circadian mismatch.

~ A lack of blue light during the day will lead to low energy and motivation. We need healthy amounts of blue light during the day as it's responsible for making us feel awake, motivated and alert.

color guide

.........

We do not recommend using the night-time glasses during the day as this will create a circadian mismatch and will actually cause issues with sleep later in the evening. Using night-time glasses during the day will be very harmful and will actually be detrimental to your health. Let me give you a bit more detail as to why:

Night-time glasses block 100% of blue light, and when your brain receives no blue light signals it assumes its night-time so it will start to prepare you for sleep even if it’s the middle of the day. So having these glasses on during the daytime will leave you feeling tired, unmotivated, sleepy, and your brain will be very confused as to what’s going on!

Over time a lack of blue light during the day will lead to low energy and motivation, and will create a circadian rhythm mismatch, so you want to make sure you’re not blocking it all out during the day!

We need healthy amounts of blue light during the day as its responsible for making us feel awake, motivated and alert. The issue we have is we get far too much blue light during the day as modern lighting, screens, and devices, as they emit very unnatural levels of blue light, so we need to bring it back into balance and that’s were our daytime glasses help.

Daytime glasses allow the healthy wavelengths of blue light through to allow you to feel awake and alert, and filter down the harmful wavelengths that cause eye damage, headaches, and eye strain.

The key here is to target the exact wavelengths of blue light that lighting and screens emit the most, this is 455nm. Our glasses have been designed to filter the 455nm range of blue light by 50% with our ScreenTime clear lens, and 100% with our DayMax yellow lens, whereas most daytime blue light glasses will only filter blue light up to 430nm, and filter none at all at 455nm making them very ineffective.

At night-time we need to make sure we block ALL blue light, as any amount getting through is enough of a signal to the brain that it’s still daytime, so our sleep hormone melatonin will be suppressed and you will have lower sleep quality, trouble falling asleep, or staying asleep, or all of these issues. So ensuring the glasses you use are blocking 100% of blue light is key for night-time!

Wow! 15+ years! + blue block glasses. Would you believe, I’ve never used Odyssey, Atari, Xbox or Packman? I had to Google-Goggle for those names in order to make this post.

I’m a dinosaur.

Thanks for the links, TrumanCash.

That’s a good price for the 3-way full-spectrum incandescent bulbs @ healthlighting.com - $11-$13. It's almost three times more @ BlockBlueLight.com - $31.

I replaced about half the white incandescent bulbs with Blue Light Blocking Amber Light Bulbs that I found @ Amazon and switched out the lamp shades for white ones.

RE: red and near infrared

In one video Dr. Jack talks about how a good friend or relative fell off the roof and caused more injury to an already injured leg (IIRC). Dr. Jack had him use his red and near infrared tech several times a day and some where in there he also took Methylene Blue as part of the healing process. I don’t recall the exact outcome, but it was sorta miraculous.

Here’s part of my repost for light therapy:

It’ll be a year next month that I added red and near infrared therapy. It’s a preventive tool that I use for 12 minutes, twice a day.

PRO300 - Red Light Therapy

Benefits (listed on the site)

Skin Health and Anti-Aging

Red light therapy (RLT) is well-documented for improving skin health by stimulating collagen production, reducing wrinkles, and enhancing skin elasticity. It promotes cell regeneration and repair, which leads to a more youthful appearance.

Wound Healing and Tissue Repair

 RLT accelerates the healing process of wounds and injuries by promoting increased blood flow and cellular activity at the site of injury. It enhances the formation of new blood vessels and tissues, facilitating faster recovery.

Pain and Inflammation Reduction

RLT has been shown to reduce inflammation and alleviate pain, particularly in conditions like arthritis, tendonitis, and muscle injuries. It works by reducing oxidative stress and promoting cellular repair.

Hair Growth and Hair Loss Prevention

RLT can stimulate hair follicles and promote hair growth, making it a popular treatment for androgenetic alopecia (male and female pattern baldness). It increases blood flow to the scalp and enhances cellular metabolism in hair follicles.

Muscle Recovery and Performance

Athletes use RLT to enhance muscle recovery and improve performance. It reduces muscle soreness, accelerates recovery after intense exercise, and increases endurance by boosting cellular energy production.

Joint Health and Arthritis Relief

RLT can reduce symptoms of arthritis, including joint pain and stiffness. It promotes cartilage repair and reduces inflammation in the joints, improving mobility and comfort.

Mood and Depression Improvement

RLT may have positive effects on mood disorders and depression by influencing the production of neurotransmitters like serotonin. It can also help with Seasonal Affective Disorder (SAD).

Sleep Improvement

RLT can help regulate the sleep-wake cycle by influencing melatonin production. It has been shown to improve sleep quality and duration, helping individuals achieve better rest.

Cognitive Function and Neuroprotection

There is emerging evidence that RLT may support cognitive function and provide neuroprotective effects, potentially benefiting conditions like Alzheimer’s and Parkinson’s disease.

Acne Reduction

RLT can help reduce acne by decreasing inflammation and bacteria levels on the skin. It promotes skin healing and reduces the appearance of acne scars.

Dental Health

RLT can promote oral health by reducing inflammation, pain, and healing times in dental procedures. It may also support the treatment of periodontal disease.

Weight Loss and Metabolism

There is some evidence that RLT can aid in weight loss by increasing cellular metabolism and reducing adipose tissue. It may enhance fat cell reduction and improve body composition.

Hormonal Balance

RLT might influence hormonal balance by affecting the endocrine system. It could help with issues like thyroid function and hormone regulation.

Immune System Support

RLT may boost the immune system by enhancing cellular function and promoting the activity of immune cells. It could help in faster recovery from illnesses and infections.

Eye Health

RLT may benefit eye health by reducing inflammation and promoting cellular repair in the retina. It has potential in treating conditions like age-related macular degeneration.

I've been using blue light blocking glasses for a couple of years and I like how they take the edge off of the computer screen and flat screen tv, much easier on my eyes. I have to put my larger blue blocking wraparound glasses over my smaller reading glasses for the computer which is rather cumbersome. I'm looking for reading glasses that block blue light, just the kind of reading glasses one buys in a drug store. I could buy those clip-on ones, though: https://www.blockbluelight.com/produ...ocking-glasses

Is it true that … the blue light from night-time scrolling can stop you sleeping?


We often blame our phone’s glare for finding it difficult to fall asleep. But our expert thinks things are more complicated

Struggling to nod off? It’s easy to blame the phone that’s just inches from your face and the never-ending newsfeed your thumb is busy scrolling as you lie in bed. But the idea that it’s the blue light emitted by your smartphone that’s disturbing you isn’t quite right.

While blue or short-wavelength light (such as daylight or that emitted by tech) does affect our circadian rhythm, things are less clear cut than we often think.

“Sleep is a complex process,” says Stuart Peirson, professor of circadian neuroscience at Oxford University.

He explains that while the receptors in our eyes that tell our brain when it’s time to be awake are triggered by cells that absorb blue light, they’re also triggered by those that absorb longer wavelengths of light (such as red) too. Which means it’s not the colour of the glow that’s the problem, it’s the brightness and length of time we’re exposed to it for – and the screens of our phones are actually pretty dim.

Daylight is 1,000 times brighter than the average light emitted by a phone. Room lighting is, on average, 10 times brighter. (This is why turning off the big light as you wind down in the evening can help you feel sleepier.)

“Technically, blue light from smartphones can affect sleep,” says Peirson. “But these effects are small unless you are using your phone for hours with a bright screen and already have sleep problems.” In lab studies at Harvard University, even around four hours of light exposure from an e-reader at full strength had only a relatively small effect: a 10-minute delay in sleep onset. In fact, your sleep is more likely to be affected by the kinds of content you’re consuming.

If you think light is impacting your sleep, Peirson says you don’t need to spend money on special “blue-light blocking” glasses. Instead, he recommends decreasing your screen time and turning down the brightness on your phone.

Thanks for the article, leavesoftrees. Some of it matches up with points discussed but the effects are greater in scope. Not to mention how negative effects add up over time. The good news is articles like this brings attention to the topic.

What comes to mind when I read it is perhaps the glasses are less effective because of quality control; how only 10-20% of the blue light is filtered out. I agree that wearing glasses is not the end all be all answer. Spend less time on the devices, TV and such because the artificial blue light destroys dopamine. Spend more time soaking in the sun. That’ll balance out the wake-sleep cycle, improve areas like focus and memory and mood. And it’s good common sense to review our exercise routines, diet, social interactions and life stressors.

Thanks, Tintin. I’ll add the photos from the Banned TED Talk 2012.

I purchased his book, “Epi-Paleo RX: The prescription for Disease Reversal and Optimal Health,” copyright 2013. I’m still flipping through it. No need to purchase if you’ve listened to many of his videos. And as you'd imagine, Dr. Jack has shared a lot more on many topics since 2013.

His banned TED talk was in 2012 where he tells how he lost 150 lbs in a year (IIRC). His son and nephew also followed his protocol and lost weight.

I’m not promoting diet changes. Dr. Jack talks about the hormone called leptin. The article helped me understand more about how leptin: 1) regulates appetite 2) maintains healthy weight. I pulled out three aha! points.

Key Points:

1. Leptin travels through your blood, via your circulatory system, to the appetite center of your brain. There, it binds to receptors that are responsible for making you feel hungry. This helps tamp down your appetite, curbing your desire to eat. Leptin also travels through your nervous system, stimulating fatty tissue to burn off fat and calories.
   .....
2. Cortisol, a hormone that’s released when you’re under stress , may make your brain less receptive to leptin and cause you to overeat.
   .....
3. Dieting may have an adverse effect on leptin production, causing leptin levels to drop. When leptin levels drop, your brain believes you’re in danger of starvation, causing your body to hold onto fat stores and reducing your ability to burn calories through exercise.

Everything You Need to Know About the Leptin Diet

• Research
• Benefits
• Risks
• 5 rules
• The takeaway

What is the leptin diet?

The leptin diet was designed by Byron J. Richards, a businessman and board-certified clinical nutritionist. Richards’ company, Wellness Resources, manufactures herbal supplements designed to support the leptin diet. He’s also written several books about leptin and its role in weight loss and health.

Leptin was first discovered in 1994. It’s a hormone produced in the fat stores of your body. Its job is to signal your brain when you’re full, triggering you to stop eating. Leptin also supports efficient metabolism. Its role in weight loss, weight gain, and obesity has been studied in animals and humans.

Leptin travels through your blood, via your circulatory system, to the appetite center of your brain. There, it binds to receptors that are responsible for making you feel hungry. This helps tamp down your appetite, curbing your desire to eat. Leptin also travels through your nervous system, stimulating fatty tissue to burn off fat and calories.

If too much leptin builds up in your blood, you may develop leptin resistance. When this occurs, the leptin in your body may not do its job effectively, resulting in weight gain. The exact cause of leptin resistance is unknown, but obesity and stress may play a role. Cortisol, a hormone that’s released when you’re under stress , may make your brain less receptive to leptin and cause you to overeat.

What does the research say about leptin?

Since its discovery, leptin has been the focus of multiple animal and human studies. Researchers have analyzed its effect on weight gain, obesity, and appetite. As reported in the Journal of Clinical Investigation, some studies in mice suggest that dieting may have an adverse effect on leptin production, causing leptin levels to drop. When leptin levels drop, your brain believes you’re in danger of starvation, causing your body to hold onto fat stores and reducing your ability to burn calories through exercise.

Another animal study, led by investigators at the University of Cincinnati Metabolic Diseases Institute, determined that leptin levels don’t affect or cause obesity in mice.

There’s no credible research to suggest that taking leptin in supplement form helps to alter leptin levels.

What are the potential benefits of the leptin diet?

Many of the principles of the leptin diet are the same, or similar, to those of other weight management programs. It advises avoiding eating late at night, avoiding eating additives such as those found in soda, and avoiding eating too many carbohydrates. The leptin diet also emphasizes the need for portion control. These recommendations represent sound nutritional advice.

The leptin diet is also accompanied by easy-to-maintain exercise guidelines, which don’t require you to work out endlessly in order to lose weight. When combined with portion control and nutritious food choices, regular exercise may help you lose weight.

What are the potential risks of the leptin diet?

Like many diets, the leptin diet imposes restrictions on what you can eat. You may find it hard to stick with the diet or you may feel unsatisfied with your food choices.

As with any diet plan, it’s best to check with your doctor before starting the leptin diet. It may not provide enough calories if you’re extremely active. It may not be suitable for children or young teens who have different caloric requirements than adults.
How to follow the leptin diet

The leptin diet centers around five rules:

1. Eat foods that supply 20 to 30 grams of protein for breakfast.
2. Don’t eat after dinner. Make sure not to eat anything for at least three hours prior to bedtime.
3. Eat three meals a day only, with no snacking in between. Allow for five to six hours to pass between each meal.
4. Reduce your carbohydrate intake, but don’t eliminate carbs completely.
5. Practice portion control at each meal. Don’t eat until you are stuffed. Stop before you feel completely full.

To follow this diet, you should learn about the caloric content in the foods you eat, but you won’t need to count calories obsessively. The diet also places a strong emphasis on eating fresh, organic foods and avoiding chemical additives and ingredients you can’t pronounce.

The need for protein and fiber is also stressed. It’s recommended that each meal contain around 400 to 600 calories, in the following general ratio:

• 40 percent protein
• 30 percent fat
• 30 percent carbohydrates

The leptin diet allows you to eat a wide range of vegetables, fruits, and protein sources, including fish, meat, chicken, and turkey. Fruit, rather than sugar-dense desserts, is the suggested dessert option. You can also eat nut butters in moderation, eggs, and cottage cheese.

Protein-dense grains and legumes, such as quinoa, oatmeal, and lentils, are also good choices. A lower carbohydrate intake may lead to gut bacteria changes and/or constipation, so choose high fiber foods as often as possible.

When you’re on the leptin diet, you’re supposed to avoid artificial sweeteners, regular and diet soda, and energy drinks. You’re also encouraged to eliminate soy products of any kind.

Because of its emphasis on smaller portions and no snacking, some people feel hungry on this diet. Drinking lots of water, or taking fiber supplements, may help.

The leptin diet requires you to control when you eat, as well as what you eat. Creating a routine that distracts you between meals, and includes moderate exercise, may help you to stick with the diet and successfully lose weight.

The takeaway

The leptin diet allows adherents to eat a variety of healthy food choices. But if you feel persistently hungry, it may be hard for you to stick with the diet. Not being able to eat when you are hungry contradicts mindful eating and listening to your body’s cues. Also, any diet plan that requires or heavily promotes supplementation is a red flag.

If you feel drawn to the leptin diet, it may yield the results you’re hoping for, but ask yourself if it is something you can stick with long-term. Long-term health is dependent on long-term healthy behaviors. No diet is one-size-fits all. If you don’t enjoy the leptin diet, there are other weight loss strategies that you can try. Ask your doctor about different approaches to weight loss, including the benefits and risks of different diets.

So this is pretty amazing!

Got my daytime blue blocking glasses today, and literally the moment I put them on and viewed my computer screen, all the strain left my eyes. It's like my eyes let out a big sigh of relief.

I'd become so used to the strain that I almost didn't even know it was there anymore until I put these new glasses on.

Highly recommended. I think I'll get the nighttime glasses too.

Street Lights -- LED vs (traditional) High/Low Pressure Sodium Vapor Lamps

Photos from space affirm that streetlights are emitting more blue spectra

"A group of environmental scientists from England have gathered photos of Earth taken from the International Space Station over the last decade showing a broad trend across Europe of nighttime artificial lighting veering much more toward the blue spectra than previously.

"Writing in the journal Science Advances, they warn that the shift 'is widely increasing the risk of harmful effects to ecosystems'.”

"The observation of more pronounced blue spectra does not in itself come as a surprise, given that many outdoor LED luminaires tend to emit more blue-rich wavelengths than the lights they have been replacing such as low-pressure sodium and others." https://www.ledsmagazine.com/lightin...e-blue-spectra

It is difficult to find any recent night time photos of cities from space. This video only shows cities from over a decade ago. You can easily spot the LEDs. Check out Osaka, Japan in 2013 at 0:58 seconds into the video.

More recent video (apparently three years ago). Notice what a big difference there is between cities. Some cities are almost totally LEDs.
