Unlock the Secret Peptide That Could Transform Your Vision—See the World Like Never Before!

Ever caught yourself squinting at your phone, wondering if there’s some secret sauce to fix your blurry vision without schlepping to the eye doctor? Enter SS-31 — a peptide that’s got TikTok buzzing like a beehive on caffeine. Folks over there swear it’s turning their astigmatism woes into clear-sighted victories, praising its magic on everything from screen glare to actual eyesight improvements. Sounds too good to be true, right? Well, buckle up, because while SS-31 technically holds FDA approval, it’s for a rare mitochondrial disorder—not your run-of-the-mill nearsightedness. As screens steal more of our daylight and myopia cases skyrocket, is this peptide the hero we never knew we needed, or just another hype train leaving the station? Let’s dive into what the experts really say — because when it comes to your eyes, guessing games just won’t cut it. LEARN MORE

TikTokers are using a peptide called SS-31 for their eye health.
SS-31 technically has FDA approval. However, it is used for a rare mitochondrial disease. Recent research looking at SS-31 to protect the retina found the drug was ineffective.
As more people stay indoors and look at screens, the number of myopia (nearsightedness) cases is expected to rise.

IF YOU ARE squinting to see TikTok, you may be wondering about the peptide elamipretide (SS-31). Right now, the platform is buzzing over this peptide elamipretide and its purported effects on improving eyesight. Some people on the app have even claimed that the peptide improved their astigmatism, a common eye condition that leads to blurry vision.

“I want to see if my eyes are improving in some way on SS-31,” said one poster. “Light sensitivity—computer screen light, blue light—it seems to be less bothersome, where my eyes can actually focus on light a little bit better.”

Another also claimed in the comments of a post that their vision improved on SS-31. “Almost three months using—just had my eye exam last week…vision improved by .25 and no more astigmatism,” they said. “Eyesight improved in two weeks!” someone else wrote.

Is there any truth to the claims that SS-31 can improve your eyesight? MH contacted four eye experts to see if there’s any truth behind these health claims.

What is the SS-31 Peptide?

SS-31, ALSO KNOWN as elamipretide, is a peptide. Peptides are short chains of amino acids, the building blocks for protein.

Peptides are a hot topic in the wellness space as more people self-medicate with them, aiming to get better skin, to help with longevity, to build muscle, and the list goes on. Right now, many peptides people are interested in taking are restricted–they’re on the FDA’s Category 2 bulk substance list, which means they are not eligible for compounding by compounding pharmacies.

However, this may change. Earlier this year, Health and Human Services Secretary Robert F. Kennedy Jr. announced on the Joe Rogan Experience podcast that he plans to loosen restrictions around their use.

SS-31 isn’t one of those. It’s technically FDA-approved—but not for vision problems. It’s currently approved by the FDA to treat Barth syndrome, a rare, mitochondrial disease that can lead to an enlarged and weakened heart. For people looking to use SS-31 for vision, they are likely getting it from a compounding pharmacy.

Does SS-31 Improve Vision?

EYE DOCTORS AREN’T convinced that SS-31 lives up to the vision-changing claims. That being said, they are keeping an eye on SS-31 for a different type of eye health issue. “Elamipretide is being investigated for improvement of age-related macular degeneration (AMD), not ‘aging eyes,’” says Jeffrey J. Walline, OD, PhD, an optometrist and the associate dean for research at The Ohio State University College of Optometry.

For AMD, Dr. Walline says the drug is experimentally injected into the eye to protect the retina. This is the part inside the eye that helps you see. “An initial phase 2 investigation reported that the drug did not meet any of its endpoints, indicating the drug was ineffective,” he points out. “The follow-up study has not been completed, so no results regarding elamipretide’s effectiveness for improving vision loss secondary to AMD are available.”

While the trial is still ongoing, there are a few takeaways worth noting. One: A whopping 86 percent of people in this clinical trial had side effects. Two, people taking SS-31 to improve their eyesight weren’t injecting the peptide into their eyes.

Dr. Walline stresses that while AMD can impact your vision, it’s not the same as needing vision correction. “Elamipretide does not have anything to do with astigmatism or presbyopia, a condition when people over 40 years old have difficulty reading close print.”

Raj Maturi, MD, clinical spokesperson for the American Academy of Ophthalmology and ophthalmologist at Midwest Eye Institute, stresses that SS-31 is not an “established treatment” for common vision issues like myopia (nearsightedness), presbyopia, or astigmatism.“Those problems are optical and structural,” explains Dr. Maturi. “A mitochondrial peptide is not expected to reverse those underlying vision conditions.”

SS-31 may help slow down macular degeneration in theory, says Bavand Youssefzadeh, DO, an ophthalmologist at Global Lasik and Cateract Institute in Huntington Beach, CA. But again, the research hasn’t proven it and this is very different from issues like nearsightedness and astigmatism. “This is not a general eyesight improver,” Youssefzadeh says.

“The peptide may eventually be useful as a treatment to help preserve visual function in patients with macular degeneration, diabetic retinopathy, or optic neuropathy,” says Muriel Schornack, OD, an ophthalmologist at Mayo Clinic. We’re just not there yet with the science.

Peptides are the Latest Response to an Ongoing Epidemic

AS MORE PEOPLE stay indoors and stare at screens, the American Academy of Ophthalmology has flagged an ongoing myopia epidemic. They report that the number of people with myopia has increased to 28 percent in the past few decades. By 2050, it is estimated to reach 50 percent.

So if you’re struggling with nearsightedness, you’re not the only one. SS-31 just isn’t the solution eye doctors favor.

Myopia is a refractive error, which means the eye isn’t the right size or shape to focus light coming in from a distant object exactly on the retina (the light-sensitive layer of tissue lining the back of the eye). “If the eye is too long, light focuses before it hits the retina; This eye would be myopic, or nearsighted,” says Dr. Schornack. “If the eye is too short, light is not in focus by the time it hits the retina. This eye would be hyperopic, or farsighted.”

Ultimately, the best medical advice is likely found at an eye doctor’s office—not TikTok. “If someone feels their vision is ‘not great,’ the first step is not to chase viral supplements or peptides, but to get a medical eye exam with an ophthalmologist, who can diagnose eye disease and recommend the right treatment options,” advises Dr. Maturi.

There are plenty of options for vision correction, from glasses and contacts to surgery, Youssefzadeh points out. As for peptides like SS-31, you’ll be going in blind on whether it actually works.
