Heavy Metal Concentrations in Human Eyes

This study aimed to measure the concentration of toxic heavy metals in the human eye's fluids and tissues in a laboratory investigation.

Laboratory investigation.

Thirty autopsy eyes of 16 subjects were dissected to obtain the aqueous, vitreous, lens, ciliary body, retina, and retinal pigment epithelium/ cho­roid. Concentrations of lead, cadmium, mercury, and thallium in ocular tissues, ocular fluids, and blood were determined using an inductively coupled plasma-mass spectrometer and expressed as ng/g. Heavy metal concentrations in ocular tissues were compared using a paired t-test.


Lead and cadmium were found in all of the pigmented ocular tissues studied, concentrating to the greatest extent in the retinal pigment epi­thelium/choroid (mean, 432 + 485 ng/g and 2,358 + 1,522 ng/g). Cadmi­um was found in the retina in all eyes (mean, 1,072 + 489 ng/g), whereas lead was found in the retina in 9 (30%) of 30 eyes (mean, 53 + 54 ng/g). Trace concentrations of lead and cadmium were detected in the vitreous (mean, 0.5 + 1.0 ng/dl and 19 + 29 ng/dl), lens (mean, 13 + 18 ng/g and 20 + 18 ng/g), and blood (mean, 0.5 + 1..2 µg/dl and 3.1. + 4.1. µ g/1) but were not detected in the aqueous. Mercury and thallium were not detected in any ocular tissues or fluids or in the blood.


Lead and cadmium accumulate in human ocular tissues, particularly in the retinal pigment epithelium and choroid.

Association between Three Heavy Metals and Dry Eye Disease in Korean Adults

The purpose of this study is to investigate the associations between blood heavy metal concentrations and dry eye disease using a Korean population-based survey.


This study included 23,376 participants >40 years of age who partici­pated in the Korean National Health and Nutrition Examination Survey from 2010 to 2012. Blood concentrations of lead, cadmium, and mercury were measured in all participants. The associations between blood heavy metal concentrations and dry eye disease were assessed using multivariate logistic regression analyses.

There were no significant associations between any of the three heavy metals and dry eye disease in males after adjusting for potential con­founding factors, but blood mercury concentrations in females were associated with dry eye disease (tertile 2: OR, 1.18; 95°/0 Cl, 0.83 to 1.69; tertile 3: OR, 1.58; 95°/0 Cl, 1.12 to 2.24; p ::: 0.009).

Mercury concentrations in the blood were associated with dry eye dis­ease. Our results suggested that controlling environmental exposure to mercury may be necessary to reduce the incidence of dry eye disease.


1.I didn't even think of this until now, but I've had 3-4 black specks in my vision the last few years. They are COMPLETELY GONE now.

2. I gifted my sister a TRS for thanksgiving. She had twins, born at 25 weeks. My niece has cerebral palsy and was more underdeveloped than my nephew. She has a speech delay, bad eyesight, tics, and a few other things I forget. After 1 month of daily TRS, her tics happen less often, her eye doctor confirmed her eyesight got better, and her speech has visibly increased!!!!

3. I read this and now I'm staring at my white ceiling and trying to see if I still have floaters. NOPE! They're gone! I've been on TRS for 6 months now. No more shrimp allergy and no more floaters. I love this stuff.

4. My eye floater went away too! I had one in my left eye for a year. It's finally gone!

5. Soooooo I received my 3 TRS bottles ... two weeks in, and eye floaters GONE like -"gone!!! What the!!! Feeling like I have more energy too, and not so tired in the mornings after waking up! Oh, and definitely sleepingbetter!I can't wait to see what else comes of my detox. I am doing both kiddies too!!! Thank you, thank you, thank you for all of your help!

Testimony 6

My back story and why I started using TRS to detox myself and my kids: I believe I am very toxic, more so than my 2 sisters. I believe I have MTHFR genetic mutation, my parents said I had reactions to my childhood vac­cines my sisters did not have. I had severe asthma, repeated ear infections, tons of antibiotics, steroids, allergies, problems with reading, lazy eye, was very shy and withdrawn, picky eater and several sensory issues. I believe I passed this toxicity to my kids. I now have PCOS, chronic fatigue, hormonal imbalance, insulin resistance, asthma issues, anxiety, astigmatism, bloat­ing, joint pain, vision problems, food sensitivities, and what I believe is can­dida overgrowth. Since I have started TRS I have noticed several things:


Ringing in the ears when I first started

A few nightmares when I first started

A couple days feeling off and tired

Headache from change in vision/astigmatism

Mild increase in food sensitivity

Bloating/knee joint pain that went away

Random Canker sore

Gains* Increased sense of peace

Eye floaters in bad eye have improved

Stronger connection with the earth/family

Improvement in the astigmatism in my left eye amblyopia (lazy eye) I just noticed today that it has improved!

Severe Dry/sensitive eyes gone

Skin/hair/scalp is not as dry

Postpartum hair loss has decreased

Teeth sensitivity went away

Slightly high blood pressure is normal

Sugar, chocolate, and carb cravings are gone

Less moody, more patience with my kids

Calve cramps I've had for years are gone increased feeling in my back shoulder blade that often went numb

Joint and back pain is gone

Frequent urge to urinate has decreased

Carpal tunnel/tingling fingers is gone

Less anxiety, don't get overwhelmed as easily

Stomach has gotten flatter

Asthma breathing issues are better

Deeper sleep/vivid dreams

Wake up more restful and energized

Amazing energy and productivity even with infant twins, a toddler and a special needs child

Brain fog is gone

Probably more that I have not yet noticed. Very excited for this journey as I believe I have a ways to go! Very thankful for TRS and how it is giving me my life back!!
