Red Light Therapy for Retinal Mitochondria
WhatExpose closed eyes to a 670 nm red light source for 3 minutes, once a week, in the morning.
WhenMorning, once a week.
Dose3 minutes per session.
For whomPeople experiencing age-related vision decline, especially those over 50.
WhyStimulates mitochondrial function and repair in cone cells, improving ATP energy for vision.
CaveatsKeep eyes closed; use only devices with safety certification (IEC 62471 exempt or RG1 low-risk) or inexpensive 670 nm bulbs designed for babies; avoid staring directly at bright light.
Berg details the research showing that this specific wavelength can optimize mitochondrial efficiency and correct damage. He emphasizes that the effects are long-lasting, with one session per week being sufficient. He warns that many commercial red light devices are not properly regulated, so he recommends looking for the IEC 62471 exempt or RG1 low-risk label, or using a simple, inexpensive 670 nm bulb marketed for babies (costing $5–$8). He insists on keeping eyes closed because infrared can penetrate eyelids, making it safe and effective. He also notes that this therapy is part of a broader field called photobiomodulation, which he expects to grow.
Mechanism
Red light at 670 nm penetrates the eyelid and reaches the retina, where it is absorbed by cytochrome c oxidase in mitochondria, enhancing electron transport and ATP production, and reducing oxidative stress. This photobiomodulation effect can restore function in damaged mitochondria.
You're going to be doing this for 3 minutes only in the morning once a week because apparently the effects last a whole week.
Also said
“It helps to make the mitochondria more efficient and also correct some of the damage in that mitochondria.”— Explains the dual action on mitochondria.
“infrared can penetrate through your eyelids very easily.”— Justifies the closed-eye safety measure.
20-20-20 Desk Reset Rule
WhatEvery 20 minutes, look at an object at least 20 feet away for 20 seconds, blinking every 5 seconds.
WhenDuring prolonged computer or screen use.
Dose20 seconds every 20 minutes.
For whomAnyone who works at a desk or stares at screens for extended periods.
WhyReleases the accommodation cramp in the ciliary muscles and prevents dry eye from incomplete blinking.
CaveatsIdeally go outside to look at distant objects; ensure you fully blink.
Berg shares his personal experience: he spent 10 hours at his computer doing research and used this rule, taking breaks to go outside and focus on distant objects. He explains that when you stare at a screen, you not only blink less often but also don't blink completely, leading to dry eye and fatigue. The 20-20-20 rule, combined with intentional blinking every 5 seconds, counteracts both the muscle cramp and the dryness. He suggests doing this by looking out a window or, better yet, stepping outside.
Mechanism
Prolonged near focus keeps the ciliary muscles contracted, stiffening the lens and causing temporary blur. Looking far relaxes these muscles. Blinking fully spreads tears and prevents corneal drying, which causes fatigue.
Personal experience
Today I had to do a lot of research on different things. I was at my computer for at least uh 10 hours so far. So every 20 minutes I have a window and I'm going to look 20 feet out and focus on something. Ideally, it'd be good to go outside. And I I have taken breaks today and and went outside.
every 20 minutes I have a window and I'm going to look 20 feet out and focus on something.
Also said
“every five seconds, you want to blink. Every 5 seconds, you want to blink as you're doing this, as you're focusing.”— Adds the crucial blinking component to the rule.
“when you're in front of the computer, not only do you not blink as often, but you don't completely blink all the way down, and your eyes can dry out.”— Explains the mechanism of dry eye from screen use.
Daily Distance Viewing
WhatSpend at least 2 hours a day outside, focusing on distant objects like tree branches, birds, or clouds, without using a phone.
WhenDaily.
DoseAt least 2 hours.
For whomPeople who spend most of their day on screens or doing near work.
WhyReverses the chronic contraction of eye muscles from near work and promotes relaxation of the accommodation reflex.
CaveatsDo not use your phone while walking; actively focus on distant objects at varying distances (20 feet, then farther like clouds).
Berg stresses that simply going for a walk while looking at a phone defeats the purpose. The key is to actively focus on objects in the environment, such as a leaf, a dog, or a cloud, and to vary the distance—first something 20 feet away, then something very far. He says this is 'very therapeutic' and necessary to undo the damage of prolonged screen fixation. He notes that inside a house, distances are limited, so going outside is essential.
Mechanism
The ciliary muscles that control lens shape become cramped from constant near focus. Looking at distant objects allows them to relax, restoring flexibility and reducing blur. This also encourages full blinking and reduces eye strain.

Also said
“the key of this whole thing is to be able to focus in on a tree branch, a leaf, a dog or a bird, or something out there in your environment and keep focusing out there for a period of time.”— Specifies the active focusing required, not just passive exposure.
Intermittent and Prolonged Fasting for Floaters
WhatStart with intermittent fasting, then periodically do longer fasts (48–72 hours) to induce autophagy and clear floaters.
WhenAs needed; space prolonged fasts weeks apart.
DoseIntermittent fasting daily; prolonged fasts of 48 hours, then later 72 hours, with weeks in between.
For whomPeople with visible floaters in their vision.
WhyFloaters are damaged proteins; autophagy recycles them.
CaveatsNone mentioned.
Berg explains that floaters are damaged proteins floating in the eyeball. He recommends getting the body into a state of autophagy through fasting. He suggests starting with intermittent fasting and then gradually extending to 48-hour fasts, and eventually 72-hour fasts, with a couple of weeks in between. He says this recycling mode will clean up the damaged proteins and the floaters will 'go bye-bye.'
Mechanism
During prolonged fasting, the body enters autophagy, a cellular cleanup process that breaks down and removes damaged proteins and organelles. Floaters, being clumped proteins in the vitreous, can be cleared through this systemic recycling.
When you start doing prolong fasting, your body's going to go into this recycling mode and start cleaning up damaged proteins, and those floaters are going to go bye-bye.
Also said
“If you have floaters, that means you have uh damaged proteins that are floating around in the eyeball.”— Defines floaters as damaged proteins, making autophagy a logical solution.
N-Acetyl-Carnosine (NAC) Eye Drops for Cataracts
WhatApply NAC eye drops to the cornea; they absorb into the lens and dissolve glycated proteins.
WhenNot specified; presumably daily.
DoseNot specified.
For whomIndividuals with cataracts, especially those linked to high sugar intake.
WhyBreaks up the cloudy glycated proteins that form cataracts.
CaveatsEffectiveness depends on cataract stage; not guaranteed.
Berg presents NAC drops as a natural remedy that has worked in both animals and humans. He explains that cataracts are often caused by consuming too much sugar and starches, leading to glycation. The drops are applied externally but penetrate to the lens. He advises combining this with a low-carb diet, intermittent fasting, and other nutrients like benfotiamine and carnosine from red meat. He says it's 'super effective' but stops short of guaranteeing results, noting it depends on the stage.
Mechanism
Cataracts result from glycation, where sugar binds to lens proteins, forming advanced glycation end-products (AGEs) that cloud the lens. NAC drops contain carnosine, which can break these cross-links and dissolve the aggregates, restoring transparency.

High-Dose Vitamin D3 Protocol for Glaucoma
WhatTake high doses of vitamin D3 with vitamin K2 and magnesium to achieve blood levels around 100 ng/mL, following Dr. Harold Shell's protocol.
WhenDaily.
DoseNot specified; target blood level 100 ng/mL.
For whomPeople diagnosed with glaucoma.
WhyReduces intraocular pressure and reverses glaucoma.
CaveatsMust be done correctly and safely; read Dr. Shell's book for details. Some may consider 100 ng/mL too high.
Berg highlights Dr. Harold Shell's book, which he says is only available on Kindle, and describes how Shell found that high doses of vitamin D3 can reverse glaucoma, but blood levels must reach around 100 ng/mL. He acknowledges that this level is controversial but says the book explains how to do it safely. He also mentions that he has found research on niacin for glaucoma, suggesting a combination approach. He strongly recommends reading the book for the full protocol.
Mechanism
Vitamin D3 has potent anti-inflammatory effects and may improve aqueous humor drainage or reduce oxidative stress in the trabecular meshwork, lowering eye pressure. The exact mechanism is not detailed by Berg, but he references the book.
He found that high doses of vitamin D3 can reverse gluccom, but you have to get your blood levels up to like a hundred.
Also said
“He also talks about a lot of other eye problems that can be improved with higher doses of vitamin D3.”— Indicates the broader potential of the protocol.
Sunrise/Sunset Viewing for Circadian Rhythm and Intracellular Melatonin
WhatWatch the sunrise or sunset without looking directly at the sun, allowing ambient rays to enter the eyes.
WhenDaily, at sunrise or sunset.
DoseNot specified.
For whomEveryone, especially those with sleep or eye issues.
WhyResets circadian rhythm, boosts intracellular melatonin (a powerful antioxidant), and supports sleep.
CaveatsDo not look directly at the sun.
Berg calls this a 'sunlight hack' and explains that it's a version of red light therapy because the sun's rays at those times contain beneficial wavelengths. He says it resets circadian rhythm much better and generates intracellular melatonin, which helps sleep and is a powerful antioxidant. He emphasizes not looking directly at the sun but around it.
Mechanism
The specific wavelengths of light at sunrise/sunset stimulate melanopsin-containing retinal ganglion cells, which signal the suprachiasmatic nucleus to entrain circadian rhythms. This also triggers the production of melatonin within mitochondria (intracellular melatonin), which acts as a local antioxidant, distinct from pineal melatonin.
If you were to watch the sunrise or uh watch the sunset and not look at the sun, but look around the sun and allow uh some of those rays to get in your eyes, you would be doing a version of this right here.
Also said
“You're going to reset your circadian rhythm much better. You're also going to generate uh more intracellular melatonin, which is going to help you sleep. It's a powerful antioxidant that does a lot of other things.”— Details the dual benefits of circadian reset and antioxidant production.

Mitochondrial Loss in Cones as Root Cause of Age-Related Vision Decline
The primary driver of poor eyesight with age is the loss of mitochondria in the cone cells of the retina, particularly in the macula, leading to reduced ATP energy for seeing fine detail, contrast, and color.
Why this matters: Reframes vision decline as an energy problem rather than just lens stiffening or muscle weakness, explaining multiple symptoms (contrast sensitivity loss, need for more light, glare, macular degeneration).
Background
Traditional explanations for age-related vision decline focus on the lens becoming rigid (presbyopia) or weakening of the ciliary muscles. The mitochondrial angle is less commonly emphasized.
Eric Berg walks through the anatomy of the eye, highlighting the cones in the fovea of the macula as the most mitochondria-dense cells in the retina. He explains that cones are responsible for daylight, color, and fine detail. As we age, we lose these mitochondria, which directly reduces the ATP energy needed for vision. This manifests in stages: first, contrast sensitivity diminishes (trouble seeing at night), then we need more light to see during the day, then glare becomes problematic, and finally age-related macular degeneration sets in. He notes that at age 60, a person needs three times the light to see compared to a 20-year-old. This mitochondrial loss is the common thread linking many eye problems, and it's why interventions that boost mitochondrial function (like red light therapy) can be so effective.
Massive loss of mitochondria in the back part of the retina, the actually most important area of your eye that you need to be able to see without glasses.
Also said
“The unique thing about this photo receptor, the cone, is this. It has the most mitochondrial pack cells in the entire retina.”— Highlights the exceptional mitochondrial density of cones, making them vulnerable to energy decline.
“When someone reaches 60 years old, and by the way, I'm 60 right now, they need three times the light to be able to see if you compare to a 20-year-old.”— Quantifies the functional impact of mitochondrial loss with a personal benchmark.
Red Light Therapy (Photobiomodulation) for Retinal Mitochondria
Exposing the eyes to 670 nm red light for 3 minutes once a week can rejuvenate cone mitochondria, improving vision and potentially reversing age-related decline.
Why this matters: Emerging research with a surprisingly simple, low-cost protocol that directly targets the root cause (mitochondrial dysfunction) rather than just correcting refraction.
Background
Red light therapy has been used for skin rejuvenation and pain relief, but its application to eye health via photobiomodulation is relatively new and not widely known.
Berg explains that red light at 670 nm can penetrate the eyelid and reach the retina, where it stimulates mitochondrial efficiency and repairs damage. He cites new research showing that just 3 minutes of exposure once a week in the morning can produce effects lasting a full week. He stresses safety: always keep eyes closed, and use devices that are IEC 62471 exempt or RG1 low-risk, or inexpensive 670 nm bulbs designed for babies (which he estimates cost $5–$8). He notes that many devices on the market are unregulated, so these precautions are essential. The therapy is called photobiomodulation, and he expects more research to emerge. He also mentions that infrared can penetrate eyelids easily, so closed eyes don't block the benefit.
You're going to be doing this for 3 minutes only in the morning once a week because apparently the effects last a whole week.

N-Acetyl-Carnosine (NAC) Eye Drops for Cataract Reversal
NAC eye drops can dissolve glycated proteins in the lens, offering a non-surgical way to reverse cataracts, especially when combined with dietary changes.
Why this matters: Presents a natural, topical remedy for a condition typically treated with surgery, challenging the inevitability of cataract progression.
Background
Cataracts are commonly attributed to aging and UV exposure, with surgery as the standard treatment. The role of glycation from high blood sugar is often underemphasized.
Berg links cataracts to the consumption of sugar and starches, which cause glycation—sugar binding to proteins in the lens, making it cloudy. He introduces NAC (N-acetyl-carnosine) drops as a remedy that has worked in animals and humans. The drops are applied to the cornea, absorbed into the lens, and break up the glycated proteins. He cautions that results depend on the stage of the cataract and doesn't guarantee success, but says it's worth trying given the low cost. He also recommends supporting this with a low-carb diet, intermittent fasting, and other nutrients like benfotiamine and carnosine (found in red meat).

High-Dose Vitamin D3 for Glaucoma Reversal
Dr. Harold Shell's protocol uses high-dose vitamin D3 (targeting blood levels around 100 ng/mL) with K2 and magnesium to reverse glaucoma, as detailed in his hard-to-find book.
Why this matters: Offers a nutritional approach to a condition typically managed with pressure-lowering eye drops, suggesting reversal is possible.
Background
Glaucoma is conventionally treated with medications or surgery to reduce intraocular pressure; vitamin D is not part of standard care.
Berg mentions Dr. Harold Shell's book, which he says is only available on Kindle, and describes how Shell found that high doses of vitamin D3 can reverse glaucoma, but blood levels must reach around 100 ng/mL. He acknowledges that some people consider this level too high, but the book explains how to do it safely. Berg also notes that he has found research on niacin for glaucoma, adding another potential tool. He recommends reading the book for the full protocol and safety guidelines.
He found that high doses of vitamin D3 can reverse gluccom, but you have to get your blood levels up to like a hundred.
Also said
“He also talks about a lot of other eye problems that can be improved with higher doses of vitamin D3.”— Indicates the broader applicability of high-dose vitamin D3 beyond glaucoma.
Vitamin B1 Deficiency and Autonomic Nervous System as a Cause of Dry Eye
Dry eye can result from a vitamin B1 (thiamine) deficiency that impairs the autonomic nervous system's control of tear secretion, not just from screen use or vitamin A lack.
Why this matters: Connects a common eye complaint to a specific nutritional deficiency and autonomic dysfunction, expanding the differential diagnosis.
Background
Dry eye is often blamed on prolonged screen time, aging, or vitamin A deficiency. The role of B1 and the autonomic nervous system is rarely discussed.
Berg explains that the autonomic nervous system controls smooth muscles that regulate glands, including tear ducts. A deficiency in vitamin B1 causes this system to malfunction, leading to reduced tear production and dry eyes. He points out that common causes of B1 deficiency include high carbohydrate intake, diabetes, and consumption of coffee or tea. Therefore, addressing dry eye may require B1 supplementation and correcting the underlying dietary factors.
When you are deficient in vitamin B1, the autonomic nervous system doesn't work that great anymore. And that system controls the smooth muscle that controls your glands. And for this example, I'm talking about the tear ducts. You're going to have a lack of secretion of tears and that's going to dry them out.

Red Light Therapy Device with Safety Certification (IEC 62471 exempt or RG1 low-risk)
Tool
For performing the 670 nm red light therapy protocol safely.
Berg emphasizes that many red light devices on the market are not well regulated, so he recommends looking for those labeled IEC 62471 exempt or RG1 low-risk to ensure eye safety. He says he will provide links to several such devices. He also advises keeping eyes closed during use regardless.
vs alternatives
Compared to the inexpensive baby bulb option, these certified devices may offer more power or features but at a higher cost.
I'm going to put some links down below of several devices that have this thing right here. It's IEC 62471 exempt or RG1 lowrisk.
Inexpensive 670 nm Red Light Bulb (designed for babies)
Tool
A low-cost alternative for the red light therapy protocol, costing around $5–$8.
Berg mentions that he will also link to a couple of red lights that don't have the safety certification but are designed for babies, consisting of a single bulb specific to the 670 nm frequency. He believes they are pretty safe, especially with eyes closed, and highlights their extreme affordability ($5–$8). This makes the therapy accessible to almost anyone.
vs alternatives
Compared to certified devices, these are much cheaper and simpler, but may lack the same power or safety testing; still considered safe with eyes closed.
those bulbs are extremely inexpensive. I think they might be I don't know $5 to $8.

Used as a natural remedy to dissolve cataracts by breaking up glycated proteins in the lens.
Berg presents NAC drops as a remedy that has worked in animals and humans. He explains that they are applied to the cornea, absorbed into the lens, and dissolve the glycated proteins that cause clouding. He notes it's not guaranteed but is worth trying due to its low cost. He also suggests combining it with dietary changes.
vs alternatives
Compared to cataract surgery, NAC drops are non-invasive, inexpensive, and address the underlying glycation process.

A reading light recommended for people over 50 to improve contrast and reduce eye strain.
Berg explains that because older eyes need more light due to mitochondrial loss, using a good reading light can make a significant difference. He specifies a high CCT warm light LED with a color temperature between 3000 and 4000K, directed at the reading surface or computer. He says this is a quick way to see better while implementing other long-term strategies.
I'm going to tell you the light I'm going to recommend. It's called a high CCT warm light LED between 3000 and 4,000K.
