A recent prospective study published in 2025 in Ophthalmic Epidemiology has identified measurable changes in the cornea of the eye following receipt of mRNA COVID-19 biological, raising new questions about potential effects on eye health. Researchers observed differences in corneal thickness and endothelial cell characteristics in healthy adults after two doses of Pfizer/BioNTech’s Comirnaty COVID shot. The corneal endothelium is a single layer of cells located on the inner surface of the cornea.1
The study included 64 participants, representing 128 eyes. Researchers examined participants before the COVID shots and again an average of 75 days after the second dose. The investigators used specular microscopy and corneal topography to measure endothelial cell density, endothelial cell morphology, and central corneal thickness.2
Measurable Decline in Corneal Cell Health
According to the study, researchers found a statistically significant decrease in endothelial cell density after administration of COVID shots compared with measurements taken before the shots were given. The authors also reported an increase in central corneal thickness during the follow-up period. The authors noted that the study followed participants for a limited period after received the COVID shots but did not evaluate long-term outcomes. They did not determine whether the observed endothelial changes were temporary or persistent.3
The researchers stated that the findings may be relevant for individuals with low endothelial cell counts. They suggested that patients with reduced endothelial reserves should be considered carefully in the context of receiving COVID shots. The study did not report clinically evident corneal disease or vision loss during the follow-up period. The authors did not establish a causal relationship between vaccination and corneal pathology but did document measurable changes detected through imaging methods.4
Prior Reports of Post-Vaccination Eye Inflammation
Earlier research documented inflammatory eye events occurring shortly after receipt of COVID shots. A multinational case series published in 2022 in the Journal of Ophthalmic Inflammation and Infection described 70 cases of ocular inflammatory conditions reported within 14 days of receipt of both mRNA and non-mRNA COVID shots.5
According to the authors, reported conditions included anterior uveitis, posterior uveitis, scleritis, optic neuritis, and rare corneal lesions. Most patients recovered without permanent injury; however, the study reported that approximately 7.1 percent of cases resulted in lasting visual impairment.6
The authors noted that while some ocular effects may reflect a generalized immune response, they also discussed the possibility that components specific to certain COVID mRNA shots could contribute to immune activation through additional mechanisms. The study proposed that elements such as lipid nanoparticles and encoded spike protein in the COVID biological may interact with innate immune pathways, though they did not establish a causal biological mechanism.7
Eye-Related Adverse Events Reported to VAERS
Several studies have analyzed reports of eye-related adverse events following COVID shots using data from the Vaccine Adverse Event Reporting System (VAERS). A report published in Ophthalmology in 2024 found that as of December 2022, VAERS contained 29,781 adverse event reports that included a total of 40,910 ophthalmic symptoms reported after COVID shots.8
Another study published in Vaccines in 2022 reviewed VAERS data from December 2020 through December 2021 and identified 6,688 reports that included ocular adverse effects following COVID shots. According to the authors, the most frequently reported conditions included eyelid swelling, ocular hyperemia, and conjunctivitis, followed by blurred vision and visual impairment.9
The same analysis also found that females accounted for the majority of eye-related adverse event reports, and individuals aged 40 to 59 years reported the highest number of ocular events. A substantial proportion of reported eye-related adverse events were associated with the Moderna/NIAID mRNA COVID shot (Spikevax) and Johnson & Johnson/Janssen (Ad26.COV2.S) COVID vaccine.10

Let’s see. Can not ask my eye doctor about this. He had a heart attack and died shortly after being coerced under pressure to take the covid shot or he’d lose his job. The last time we spoke, we shared a conversation about how unfair the hospital policies were on patients and employees. I was telling him the story my wife told me, being a hospital worker; They were having to call the crash cart several times a day for every single day the covid vaccine was being given. Then he was suddenly dead. He’s not here anymore. Was only in his mid 50’s. I personally know of several people whom had detached retina’s, lost measurable vision quantity, etc. Good old covid shot.
The numbers in this article represent a minute micro fraction of harm that really happened. Yet the program persisted for years after this information came flooding in the front doors. The pertinent question; Why didn’t they stop at that time?
The answer is the entire system is designed to milk every dollar possible in every way possible. The waste of human manpower, time, energy, incalculable in the end. We could have skipped the preliminary studies, by skipping the delivery of a harmful substance, forgoing any need for subsequent care or reporting during the follow up phase. But then how would these people get to stay ultra rich at the expense of everyone elses health?
There could not possibly be something smarter to do with our time in the entire world. Developing, producing, delivering, observing, profiting. Vaccines! Stab everyone in the arm with toxic substances. Forever. No exceptions. Job creation. The vaccination program at this scale in modern times was never about health. Infection disease at scale had already subsided before mass vaccinations ever came to market in this manner. Facts over an indoctrination of belief in a false god. Repeat after me; Safe AND effective. ChaChing! $$$$$$$
Would you have paid a thousand dollars cash out of pocket for that shot if this was a voluntary expenditure? The true cost of each individual shot is far more than it’s market cost as a singular dose product. There are untold trillions of dollars of wasted time and money behind that final product delivery. Your tax dollars, hard at work. As long as the government remains in the business of funding this waste, fraud, and abuse, you have no choice but to keep paying. Yet another case of taxation without representation. Now with egregious incurable physical harm! As seen on TV! (if you still have functioning eyes that is.) Who’s still buying this?
Sadly if enough people are gullible or fear-mongered enough. I guess it’s easier to believe that vaccines actually prevent diseases.
I’ll take things that never happened for $500 Alex.
What about retinal hemorrhage?
Within 24 hours of getting the experimental Moderna injection in 2021, my 31 year old patient experienced an insidious onset of total loss of peripheral vision, bilaterally. She had to be her own advocate and push for an MRI since she thought it might be MS. MRI showed no brain lesions, but an MRI cannot detect interstitial inflammation. Her vision, thank God, returned and she never got jabbed again. Think her doctor reported it to VAERS?? 🙄
Another tragic health event from getting the “poison shot”. It’s earning that name more and more as the months and years go by! We live in a sick new world! Jesus is still the answer! Trust Him! And don’t ever get another shot or booster!!!
I know someone who is almost blind after the covid jabs were given. Their vision was far from perfect to begin with. Glad I had access to the right voices before the covid vaccine campaign began. And people are wondering why measles (a disease that was supposedly eradicated 20+ years ago) is back in the headlines. I’m convinced that vaccines are diseases in the vial anyway.
Excellent comments The reporting system is a joke particularly if the government is involved in it. VAERS is the perfect illustration. They make it cumbersome time consuming and the data collected is irrelevant since Big Pharma is the puppet master! A great site to report bad outcomes from the clot shot is howbadismybatch.com Easy to fill out one just needs their batch number which should be on one’s vax card! Support the people doing this great work. They have the real numbers and the real side effects Anyone can fill it out I have done it for many people it’s super easy and one just has to look at all the graphs to know the real stoey
I never had the vaccine but in 2021 a newly vaccinated health care worker shed on me at my home. She was providing care AFTER being released from 4 months of being hospitalized for a broken neck where I never caught the illness. The very next day I began to feel unwell, the following morning a cytokine storm hit me hard. Fortunately in 2020 I researched the illness and deaths taking place in Italy and had developed a treatment plan that included all the usual supplements but included Ivermectin and Hydroxychloroquine. I had also learned that 400mg melatonin suppository would stop a cytokine storm in a few hours and that it works better than anything the hospitals use. I also nebulized hypochlorus acid 5.0pH that prevented the pneumonia. I recovered from the cytokine storm in 14 hours and recovered from Covid in another 6 dqys. BUT I had long Covid for a few months. I consider myself as having been jabbed because I continue to have many of the problem vaxxed have. Cataracts, liver, brain issues., etc.. I believe EVERYTHING in the careworkers jab the day before coming to help me was transmitted to me.
