Blue-light-blocking glasses


Blue light—sounds lovely, doesn’t it? Actually, it's often the opposite. This is the high energy light emitted by electronic devices and the sun, and we're all seeing waaaay too much of it, thanks to our growing dependency on screens. Using electronic devices is part of living and working in the world today, but it can create some unpleasant symptoms for some people. It’s called digital eye strain, with symptoms that range from dry eyes and blurry vision to headaches and fatigue. In addition, blue light at night can affect your ability to get a good night’s sleep and long-term exposure may worsen your eyesight over time. Blue light-blocking glasses—which look just like regular glasses with tinted lenses—may improve your sleep, and many people swear by them for relieving fatigue and other symptoms.

Sleep Junkies Podcast: Hacking light for optimal sleep and circadian biology

A practical guide to optimising your sleep and circadian biology with light exposure in the day and blocking blue light at night. We talk to Thaddeus Owen, the Primal Hacker about blue light blocking glasses, getting naked outdoors in the morning and lots more. Skip to highlights 1:44 What is biohacking? 4:57 Dave Asprey and modifying your biology 6:20 The pivotal moment when Thaddeus decided to pursue a life of optimal health 9:00 Primal Hacker: combining cutting edge science and ancestral health 10:32 Jumping into ice-holes, cold adaptation and cryotherapy 13:23 Thaddeus' TED Talk on light hacking 15:04 Light hack #1: getting sun exposure in the morning 16:15 How morning sunlight stimulates hormone and neurotransmitter production 17:40 How morning sunlight preconditions your skin to withstand ultraviolet light 20:40 New research which shows there are photoreceptors in the skin 21:30 How to be naked in the sun, even in a busy urban environment 22:51 Lux levels, indoor vs outdoor light intensity 26:22 Using consumer light therapy technology, Retimer glasses 31:07 How morning sunlight acts as a 'brake' for melaton 33:48 How do I get natural light if I work indoors all day? 37:30 Why do we need to block out blue light at night? 40:35 Blue blockers; wearing at night vs wearing in the day 43:50 Blue light blocking apps and software for laptops, phones and tablets 45:18 F.lux vs Iris - pros and cons 48:15 How to choose a pair of blue-blocking glasses 50:41 BPI 550 tint glasses 52:51 Recommended brands for best blue blocking glasses 54:32 How to check if your glasses are blocking the right wavelengths 56:51 How to create a blackout in your bedroom at night 59:27 Thoughts on smart lighting/circadian lighting for the home 01:01:46 Summing up: Light is free. It doesn't have to be complicated. For 200,000 years, human physiology has adapted to live in sync with the daily cycle of night and day. And natural light is the most important environmental cue that helps to synchronise our biology to the 24 hour, or circadian rhythm. But in the 21st century, artificial lighting, technology and 24/7 society has separated us from nature, and as a result, many of us, as a result of spending too much time indoors, too much time in front of screens, or staying up too light, suffer the health consequences of disrupting our circadian rhythms. In today's podcast we talk to biohacker Thaddeus Owen, who for the last 12 years has been studying, and implementing ways to achieve optimal health, including using the latest research into how light affects our physiology and our sleep. In this episode we go in-depth into explaining some practical ways to improve your sleep health, and general well-being with 'light hacking' including: tips and strategies for achieving optimal sunlight exposure in the morning and throughout the day how sunlight contains information that triggers hormone production at different times during the day how to choose the best pair of blue light blocking glasses comparing blue light blocking apps like F.lux and Iris and lots more. We hope you enjoy the episode! This Episode's Guest Thaddeus Owen is the co-founder or PrimalHacker.com. A certified Bulletproof Coach from the first ever class of coaches, holds a personal training certification, nutrition certification, Master’s degree in Holistic Nutrition and studied Chemical Engineering a long time ago.


The Primal Example Podcast: Circadian Rhythm, Blue-Light, Melatonin & Chocolate

When it comes to the most important lifestyle factors for optimal health, light exposure takes the cake. Sure, food and exercise are important. But did you know that being exposed to artificial light can change what your body does with the food you eat? Recent research has linked artificial light exposure to cancer, obesity, diabetes and heart disease. This is a crucial concept to understand because most of us are exposed to artificial light on a 24-hr basis. We sleep with our TVs on at night and stare at cell phones and computer screens all day while we are at work. This artificial light exposure tricks our body into thinking that it is daytime all of the time, causing hormonal imbalances and a cascade of adverse health conditions. The invention of the light bulb may simultaneously be the best and worst invention in human history. On one hand, we have been able to advance society and create relatively safe living conditions for much of the world’s population due to the invention of the light bulb. On the other hand, we are now forced to deal with the consequences of introducing a new set of instructions to our biology. We didn’t evolve alongside artificial light, so it is new to our biology. We are still figuring it out. While I suspect that our biology will adapt to better deal with artificial light exposure in the future, at this point in human history it’s vital for our health that we do everything in our power to avoid blue-light (especially at night) if we want to avoid conditions such as obesity, diabetes and cancer Next episode is another Q&A episode so ask us any questions you have regarding ketogenic/low-carb diets, the coconut oil vs. AHA fiasco, or any other health topics you may have questions about.

ReWild Yourself: Is Blue Light the New Smoking? - Dr. Edward Carome

Most of us are exposed to an abundance of artificial blue light on a daily basis, via our modern technology (lamps, cellphones, computers, TVs, etc). Our bodies physiologically respond to light from the blue portion of the spectrum with a state of wakefulness, via the suppression of melatonin production. This constant stream of artificial blue light is wreaking havoc on our circadian rhythms. Today’s guest, a physicist, is one of the leading experts on this topic — Dr. Edward Carome. In this episode, you’ll learn how blue light interacts with our bodies by suppressing melatonin-production and some surprising, and not often discussed, effects this can have on us. Dr Carome relays some excellent strategies on how to minimize blue light exposure, particularly in the evening hours. Whether you are using these blue-light-producing modern devices on a daily basis or not, the information in this interview is extremely important! Enjoy, and please share your thoughts in the ReWild Yourself! Facebook group! I’d love to hear what strategies you are utilizing to safeguard your circadian rhythm! Episode Breakdown: * Dr. Carome’s background in light * The effects of blue light on the pineal gland * Artificial light from our modern devices * Dr. Carome’s experience with melatonin * When to use blue-blockers to support your circadian rhythms * The powerful effects of melatonin * Amount of blue light in LEDs, Incandescents, Tungstens and other bulbs * Do short bursts of blue light at night cause melatonin production to cease? * The best blue-blocking products and how to use * Crisper focus outdoors wearing blue-blocking glasses * Concluding thoughts


The Mindset Athlete Podcast: Sleepwells blue light blocking glasses with Denis Brzozowki & Matt Pyke

Pyke & Co was founded by two entrepreneurs, Matthew Pyke and Denis Brzozowski. We are both founders of two digital marketing agencies, Fly High Media, and Wolfden Creative. Our product Sleepwells is a byproduct of that. Naturally, building a business isn’t easy, with it comes a mountain of responsibilities such as managing teams, projects, business growth, personal development and much more. This often comes at a cost. 9 times out of 10, that cost is good sleep. We have both experienced countless nights in front of phone and laptop screens until 2 am which, needless to say, is too late to get a good night’s sleep. We have both suffered from effects from the over-use of device screens before sleeping, which were stress, eye-strain, headaches, loss of energy and unbalanced sleeping patterns. Other effects can go as far as depression and weight gain. We decided to do something about this. We wanted to put something in place for people that want to get a better night’s sleep. We proceeded to conduct research into the loss of sleep, its effects and how to prevent it. Very quickly we found that a tinted orange lense can prevent just that. Not only does this method prevent blue light entering your eye, but it can also stop the glare from computer screens. No artificial medication, no sleeping pills, just a proven method backed by extensive research from Harvard University. Your mobile phones, tablets, laptops and tv’s all release more than their fair share of blue light, which is short wavelength and high frequency on the visible light spectrum. The light suppresses a hormone called melatonin, which helps us get to sleep. In an ideal world, you wouldn’t use any devices which emit blue light between 1 and 2 hours before sleep. But unfortunately, we live in the 21st century, where our phone and laptop screens are a big part of our professional and private lives. This is where the Sleepwells come in. Our top of the range Blue Light Blocking Glasses are designed to block the blue light entering your retina which effectively prevents you from getting a good night’s rest. They are designed to be comfortable and stylish at the same time. Denis is a designer at heart, and the CEO of a creative marketing agency, he quickly came up with prototypes of the product and its packaging, making sure that great care is taken with each and every product that goes out to our customers. We are absolutely in love with the Sleepwells Classics range, and it is indeed our first range available. We are constantly working on new ways to improve and expand this product, which includes: Fit-Over glasses, Clip-Ons as well as a Children’s Range. Not only do we help people take care of their health and sleep, but we also help our community. Since day one, for every unit of our products we sell, we donate £1 to Losing My Sight UK, a non-profit charity focused on providing activities and support for the visually impaired and blind. LMS is one of our proud partners, and we will continue to do our best to support them in any way we can.

Decoding Superhuman: How to Optimize Your Light for Sleep, Energy, and an Epic Life with Andy Mant

Andy Mant is the Founder and CEO of BluBlox, a company who produces high-quality blue light blocking glasses. Andy and Boomer discuss the role of melanopsin, how to regulate blue light, and the role of circadian rhythms for performance. "When the sun rises in the morning and as it actually sets in the evening, the intensity of light changes. During first sort of sunrise periods, you're going to have a very low lux light. It is probably about sort of 1800 Kelvin on the sunrise and the sunset. It's actually not really that difficult to look at and it also contains a lot yet less frequencies of invisible light like UV." Andy Mant, CEO of BluBlox Who is Andy Mant? Andy Mant is the founder and CEO of BLUblox, a company specializing in evidence-based advanced light filtering eyewear. Andy started BLUblox after becoming dissatisfied with the quality and standards of blue light blocking glasses available and so set about to design lenses that match the evidence in the academic literature. Andy was born in the UK and moved to Australia in 2011. After moving and about 2 years after arriving Andy’s gained a lot of weight and become chronically fatigued and lacked energy. Traditional dietary approaches only worked to a certain degree and after stumbling across light and health Andy forged a passion and niche understanding of all things light related to health. Today Andy is a leading figure in managing light to improve health and wellbeing.
