As you get older, your vision naturally declines.
Even if you have never needed glasses or contacts, you could start to struggle with vision as you age.
Fortunately, a good vision supplement can help. Today, you can find hundreds of supplements that support vision in various ways. Some supplements even claim to reverse blindness, fix poor eyesight, and improve your vision, among other dramatic benefits.
Not all vision supplements are made equal, however. Some are built on junk science. Others contain unlisted dosages of unproven ingredients.
As vision supplement experts, we want to help. Here are our rankings of the best vision supplements and eye health formulas available online today.
We tested and analyzed the most popular vision supplements available today. We contacted manufacturers and pored over lab reports. We combed through thousands of peer-reviewed studies to verify the advertised benefits of top vision supplements.
Based on our analysis, here are the best vision supplements available in 2021:
Zenith Labs Vision 20
Vision 20 is an advanced vision support formula from Zenith Labs. The supplement can purportedly support healthy vision for older adults at any age. It’s also one of the few supplements on this list formulated by a real doctor: Dr. Ryan Shelton of Zenith Labs created Vision 20 to support vision.
Vision 20 works because it contains “vision detoxifiers,” according to Dr. Shelton. As you get older, ROS toxins stiffen and blur the lens of the eye. Dr. Shelton insists his formula is not “a temporary, band-aid fix”; instead, he claims it’s a “natural solution, backed by real research” to support vision in a significant way. Vision 20 contains ingredients like carotenoids and zeaxanthin, two of the most-researched ingredients for eye health and vision.
Performance Lab Vision
Performance Lab’s Vision is an eye support supplement that claims to give you sharp, crystal clear visual performance while supporting overall eye health. According to Performance Lab, you can enjoy high-speed focus, motion detection, and even “night vision” after taking the formula. The supplement can also purportedly help reduce vision-impairing effects of glare while fighting macula-damaging effects of blue light rays.
To achieve these benefits, Vision contains ingredients like blackcurrant extract, bilberry extract, lutein, zeaxanthin, and astaxanthin, all of which are found in other supplements listed here. By flooding your body with anthocyanins and other ingredients, Vision may be able to support inflammation within the eyes, which could help with vision. And, at $39, it’s one of the more competitively-priced options listed here.
1MD’s VisionMD is a nutritional supplement formulated by real medical doctors. The supplement works in a straightforward way: 1MD looked at the nutrients recommended by the National Eye Institute, then created a supplement that exceeded these recommendations.
VisionMD contains Lyc-O-Mato lycopene, EVTene mixed carotenes, and OptiLut with lutein and zeaxanthin, three proprietary formulas that have been studied for their effects on vision. According to 1MD, the formula is “revolutionary” and “clinically proven to support eye health and aid proper vision.” By adding vitamin E and astaxanthin to the mix, VisionMD can also help prevent oxidative cellular damage, improve visual acuity, and promote overall vision health, among other benefits.
Nuzena Vision Support +
Nuzena’s Vision Support + is an eye health supplement that claims to help protect against AMD, support macula health, and support natural vision, among other benefits. The supplement may have the most attractive packaging on this list. By helping to protect against age-related macular degeneration (AMD) and other common issues, Vision Support + may support vision and eye health in multiple ways.
Nuzena is also transparent with most ingredients and dosages, making it easy to compare the formula to other supplements sold online today. Vision Support + contains high levels of vitamin C, vitamin E, vitamin B1, vitamin B2, vitamin B3, biotin, vitamin B12, zinc oxide, and other popular nutrients. It also contains a proprietary “Vision Support + Blend” that contains lutein, NAC, bilberry extract, alpha lipoic acid, eyebright, zeaxanthin, quercetin, and other proven ingredients.
Lutenol is a vision support formula that supports healthy eye function, supports retina, lens, and macula health, and supports antioxidants with vitamin A and lutein. The manufacturer claims the formula has been carefully formulated to blend high-quality vitamins and minerals with more unique ingredients like herbal extracts and carotenoids. By taking two VitaPost Lutenol capsules daily, you can purportedly support the general nutrition of your visual system.
Lutenol contains ingredients like bilberry, which contains anthocyanosides that specifically support the retina, according to the manufacturer. Lutein and zeaxanthin, meanwhile, are naturally concentrated in a healthy visual system (including your eyes and brain), and Lutenol delivers a small dose of both nutrients. According to customer reviews on Lutenol.com, the supplement “improved vision”, “helps prevent further eye deterioration,” and comes with “no side effects.”
Advanced Bionutritionals Advanced Vision Formula
Advanced Bionutritionals Advanced Vision Formula is a vision and eye health supplement with over a dozen ingredients. The supplement contains ingredients found in other formulas listed here, including astaxanthin, bilberry, lutein, and zeaxanthin. It also contains ingredients we don’t see in other formulas, including Cognizin, beta glucan, ginkgo biloba, and L-taurine. These ingredients are commonly found in nootropics, although they could support vision by supporting cognition.
According to customer reviews shared by Advanced Bionutritionals, the supplement has helped users “see much better”, improve their night vision, and clear up eye health issues, among other benefits. One woman claims her doctor told her that her “eyes are actually improving” after taking Advanced Vision Formula.
PureHealth Research Complete Vision Formula
PureHealth Research’s Complete Vision Formula is a vision support supplement priced at $49 per bottle. The supplement uses vitamin C, vitamin E, zinc, copper, bilberry, eyebright extract, lutein, and zeaxanthin to support vision in various ways. According to PureHealth Research, the ingredients in Complete Vision Formula may help nourish the body with eight natural ingredients scientifically proven to support and maintain healthy eyes and vision.
According to customer testimonials featured on PureHealthResearch.com, some customers have been able to genuinely improve their vision after taking Complete Vision Formula. One woman claims she believes her vision “is a bit more clear” and she no longer wears glasses as often after taking Complete Vision Formula. Another claims to have “more clearer vision” after just three weeks of taking the supplement, while another user claims to be “seeing better now” thanks to Complete Vision Formula.
Eagle Eye 911
Eagle Eye 911 is a vision health supplement from PhytAge Labs. The supplement is marketed as an optimal eye health and vision support formula that delivers 2x the protection of typical vision supplements. PhytAge Labs also claims their Eagle Eye 911 supplement will improve overall vision, promote optimal eye function, support retinal tissue, help reduce eye strain, and provide other benefits we rarely see advertised with other vision health supplement companies.
To achieve these dramatic benefits, PhytAge 911 has added a small blend of ingredients to their formula. The largest ingredients in Eagle Eye 911 are L-taurine (400mg), NAC (200mg), grape seed (100mg) and quercetin (100mg). These ingredients could support vision in a small way by functioning as antioxidants. PhytAge Labs also backs up all purchases with a moneyback guarantee.
Provisine is similar to Vista Clear, Divine Vision 12, ReVision, and other supplements on the bottom of our list. It contains an undisclosed blend of ingredients and dosages while claiming to dramatically support vision and eye health. The supplement was created by an optometrist named Dr. Dean Avant who has 32 years of industry experience “treating every eye condition known by science,” although there’s limited information about Dr. Avant available online.
Provisine is also one of the few supplements on this list that specifically claims to improve your eyesight. According to Provisine.com, the supplement is “an expensive and completely natural solution that gives you back your perfect 20/20 vision” within weeks. If you had 20/20 vision before and no longer have it, then Provisine claims to help – “no matter how advanced your vision loss is,” according to the official website.
Eyesight Max is a nutritional supplement that purportedly targets the real cause of vision loss. While other supplements use antioxidants and vitamins to target vision health, Eyesight Max uses unique ingredients to support vision in a significant way.
Like Provisine, Eyesight Max is one of the few supplements that specifically claims to improve your vision. According to the official website, the supplement will give “anyone who uses it a crystal clear 20/20 vision, in just a few weeks” without prescription drugs, surgery, exercises, or any effort. The manufacturer provides little information about ingredients or dosages upfront, although the company claims their formula is “guaranteed to work” regardless if your vision loss was caused by type 2 diabetes, macular degeneration, cataracts, glaucoma, eye injuries, or aging – another claim that few other supplements here can make.
Vista Clear is a vision health supplement based on an “ancient Aboriginal recipe,” according to the official website. This recipe has purportedly been used by indigenous people in Australia for thousands of years to see better. The company claims one Australian tribe has eyesight that’s four times sharper than our eyesight. Today, the maker of Vista Clear used a similar recipe in their supplement, claiming the Aboriginal diet has unique vitamins and minerals not found in a conventional diet.
Vista Clear contains 26 antioxidants, herbs, vitamins, and minerals, including unique options like Bacopa monnieri, chamomile, lemon balm, skullcap, hawthorn, and St. John’s wort – all of which are rarely found in other vision health supplements. While other supplements focus on high dosages of a few proven ingredients, Vista Clear emphasizes low doses of dozens of ingredients, claiming their formula can “work wonders for you.” At $79 per bottle, however, it’s unusually expensive compared to other formulas on this list.
Divine Vision 12
Divine Vision 12 is a vision supplement from Divine Body Health. The supplement purportedly uses Biblical ingredients to support vision health in a significant way. The makers of Divine Vision 12 are mysteriously vague about what’s inside the formula, how it works, and what you can expect to achieve after taking the supplement.
At $69 per bottle, Divine Vision 12 is priced higher than many competing formulas listed above, yet the manufacturer provides limited information to justify the high cost. However, all Divine Vision 12 purchases are backed by a 180 day moneyback guarantee. If you don’t experience any benefits within 6 months of taking the formula, then you’re entitled to a refund.
ReVision is a nutritional supplement built on a “6-second trick” that can purportedly “restore perfect eyesight tomorrow.” Priced at $70 for a one month supply, ReVision is one of the priciest supplements on this list, although it seems to come with lower dosages than competing supplements above.
The makers of ReVision have launched a new version of the formula in recent months. It’s called ReVision 2.0. According to the manufacturer of ReVision 2.0, you can support healthy vision and brain function by taking the supplement for 3 to 6 months. The company also claims their formula is “100% natural, safe and effective.”
Bonus Vision Guide #1: Sniper Vision System
Supporting vision isn’t just about taking supplements. It’s also about adjusting diet and lifestyle factors. In Sniper Vision System, you can discover strategies to purportedly improve your vision, including dietary changes to make, exercises to perform, and simple tricks you can perform at home to improve your vision.
According to Dr. Richard Simmons, the man who created Sniper Vision System, you can “easily restore your eyesight to a 20/20 bulletproof vision” by implementing the lessons in the guide. The strategies were purportedly based on information found in an old sniper’s journal. Snipers need good eyesight to be effective. With Sniper Vision System, you can discover proven strategies used by snipers to improve their vision, as recommended by Dr. Richard Simmons. All purchases also come with two bonus guides, including Clear Eyes Protocol and the Eye Test home Kit.
Bonus Vision Guide #2: Natural Vision System
Natural Vision System is a collection of eBooks and videos that can purportedly improve your vision using natural therapies. By implementing these therapies, you can purportedly improve your vision dramatically, according to NationalVisionImprovement.com.
Natural Vision System was developed by Dr. Michael Tonka, the Chief Health Researcher at National Vision Improvement.
Dr. Tonka claims his eye health advice can help with nearsightedness, farsightedness, macular degeneration, cataracts, macular edema, eye imbalance, eye pressure, eyestrain, and more. He even claims his guide can help with astigmatism, which is a physical misshapenness of your eyes – something other eye health guides don’t claim to target. Better yet, he describes his recommended protocols as “fun”.
Bonus Vision Guide #3: Koori Vision Fix Protocol + Home Eye Test Kit
Koori has developed a vision treatment protocol in partnership with a man named Jake Turner. According to KVisionFix.com, the protocol is an “easy way to treat vision loss and greatly improve your eyes to 20/20 clarity.”
In the guide, you can discover a special recipe for improving vision and restoring 20/20 eyesight. One customer claims to have been nearly blind before following the recommended treatment protocol, dramatically improving eyesight within weeks just by taking a green smoothie.
Today, Koori claims their Vision Fix Protocol and Home Eye Test kit are “a scientifically proven way to correct your failing eyesight and achieve an amazing 20/20 vision in as little as 3 weeks,” – all by making foods, smoothies, and recipes using common ingredients found at home or any supermarket.

How We Ranked
All vision supplements claim to support vision in various ways. However, no two vision supplements are made equal. To separate the best and worst vision supplements available today, we used the following metrics:
Science-Backed Ingredients for Vision: You’re taking a vision supplement to support your vision. That’s why we put a heavy emphasis on supplements that used science-backed ingredients to support good vision. Some ingredients have been studied extensively to validate their effects on vision. Other ingredients contain antioxidants that could support inflammation but are unlikely to transform vision overnight.
Clinically-Based Dosages: Some vision supplements contain the right ingredients at the wrong dosages. We preferred supplements that used clinically-based dosages, including the same dosages used in peer-reviewed trials and research.
Manufacturer Reputation: Some manufacturers have a longstanding reputation for creating effective supplements. Other manufacturers source cheap products from overseas factories, then add their own label and sell them online. We considered manufacturer reputation in our rankings.
Medical Advisory Board: The best supplement companies have a medical advisory board filled with medical doctors (MDs). Other supplement companies have naturopathic doctors (NDs) or other PhDs on their advisory board. We emphasized vision supplements that were formulated, approved, or recommended by doctors.
Customer Reviews: Vision is subjective. We can’t personally test each supplement and then complete an eye exam. Instead, we need to base some of our analysis on customer reviews online. We considered customer reviews in our rankings, including independent reviews from real customers.
Pricing & Value: The vision health supplements above ranged in price from $30 to $80. You can find plenty of cheaper and more expensive vision health supplements online. We preferred supplements that offered good value at their specific price range. If you’re spending $80 on a vision health supplement, then you want to get $80 worth of ingredients.
Moneyback or Satisfaction Guarantees: Vision is complicated. A supplement might work for some people but not others. Some people have poor vision because of oxidation issues within their eyes. Others have physical damage that can’t be reversed without surgery. We preferred supplements with a moneyback or satisfaction guarantee.
Honest Advertised Benefits: The vision supplement industry is filled with scams. Shady supplement companies claim you can cure vision problems, restore 20/20 vision, and dramatically improve your vision overnight – all by taking a simple supplement. For most people, this is impossible – and it’s dishonest. We emphasized supplements with transparent benefits while punishing supplements with dishonest benefits.
Based on all of these factors, we created our ranking of the best vision health supplements above.
Do Vision Supplements Really Work?
Some vision supplements claim to support your vision. Others claim to improve your vision and restore 20/20 vision. Do vision supplements really work? or is the industry one big scam?
Many ingredients, including lutein, zeaxanthin, astaxanthin, vitamin E, and vitamin C, have been shown to support vision in a significant way. These ingredients work as antioxidants, but they’re found in particularly high concentrations within the eyes. If your vision issues are linked to inflammation, then it’s possible a supplement could help.
However, most people have vision issues because of physical damage to the eye. Because of age and other factors, your eye health tends to worsen over time. Although some vision supplements claim to improve vision in anyone, regardless of the case, no vision supplement will reverse serious physical damage to the eye.
We’ll review some of the scientific evidence behind vision health supplements below.
Vision Supplement Benefits: What Does Science Say?
Lutein is one of the most popular vision supplement ingredients available today. Many supplements use lutein to support vision. Lutein is a carotenoid linked with anti-inflammatory effects. It’s true that some studies have linked lutein to a reduced risk of age-related macular disease, which is the leading cause of blindness and vision loss. Some studies also show that lutein can support cognitive function, cardiovascular health, and other benefits.
Lutein works because it’s an antioxidant. Like other antioxidants, lutein could help manage inflammation within your body. Lutein, however, seems to specifically help with inflammation in your eye and brain. In this 2018 study, for example, researchers found that lutein could help improve multiple aspects of eye health.
Similarly, this 2017 study found that a combination of lutein and zeaxanthin (another antioxidant) could be particularly effective for supporting eye health. Milk, fruits, and vegetables (especially leafy green vegetables) are particularly rich with lutein and zeaxanthin. If you have a balanced diet, then you are unlikely to be deficient in lutein and zeaxanthin, which means a supplement won’t help. However, if you have a poor or imbalanced diet, then lutein and zeaxanthin supplements could provide crucial support for vision.
Zeaxanthin may also work on its own without lutein. As reported by the American Macular Degeneration Foundation (AMDF), zeaxanthin plays an essential role in eye health. According to one study cited by the AMDF, zeaxanthin helps protect the retina of the eye from the damaging effects of light, which could help reduce the risk of degeneration of the eye.
Other studies have validated the use of lutein, zeaxanthin, and other carotenoids. In this study, for example, researchers found that carotenoids like lutein and zeaxanthin can positively impact eye health. Researchers applied these natural chemicals to quail eyes, then observed significant improvements in the retina. Quail eyes are similar to primate eyes, which is why researchers believe lutein and zeaxanthin could improve eye health and vision.
Some vision supplements contain bilberry extract. In fact, it’s one of the most popular fruit extracts found in vision supplements. According to WebMD, bilberry has been popular for eye health since the Second World War, when Royal Air Force pilots purportedly ate bilberry jam to get better vision at night. Today, we know the RAF’s advantage came from radar – not bilberry jam. However, the legend persists, and bilberry remains popular today in vision health supplements. Despite its popularity, bilberry has not been linked to significant vision health benefits in any major trials in humans. One study reviewed evidence on bilberry and found it was hard to “sort out the anecdotal report from the placebo effect.”
Some vision supplements use unique ingredients like choline to support vision and cognition. Your brain processes the optical data from your eyes, which is why brain health is crucial for vision. In this 1998 study, researchers gave participants 1g of CDP-choline per day for 15 days, then observed a 30% improvement in visually evoked potentials (VEPs), suggesting that choline could improve vision when taken at high doses.
Ginkgo biloba is another popular cognitive supplement ingredient also found in vision supplements. In this 1999 study, researchers analyzed the effects of ginkgo biloba on eye health and found it increased ocular blood flow velocity. Participants took ginkgo biloba or a placebo, then experienced significant improvements in blood flow to the eyes.
Beta glucan is another popular vision supplement ingredient. In this 2013 study, researchers found that a combination of beta glucan (from barley) and mushroom extract significantly reduced glycemic response in diabetics. That means diabetics experienced less of a blood sugar spike from the foods they ate. The study did not analyze the effects of beta glucan on eye health, and most studies have not analyzed beta glucan’s effects on vision. However, diabetics who suffer from blurred vision may consider taking a beta glucan supplement.
Side Effects of Vision Supplements
Vision supplements, like most supplements, are not associated with significant side effects.
By FDA regulations, supplement companies must use ingredients and dosages that are Generally Recognized As Safe (GRAS). That means manufacturers must use ingredients and dosages from a specific, FDA-approved list. The FDA has determined these ingredients and dosages are not linked with significant side effects when used by healthy adults.
As long as you follow the recommended dosage instructions on your vision supplement, you should not experience significant side effects.
If you are taking medication or have any medical condition, then talk to your doctor before taking a vision supplement – or any supplement.
FAQs About Vision Supplements
Q: What is low vision?
A: Low vision is a medical term describing a vision below normal (20/70 or worse) that cannot be corrected using conventional glasses or contacts. Low vision is different from blindness, although it could interfere with normal activities like reading and driving.
Q: What is legal blindness?
A: You are considered legally blind if your best corrected central acuity is less than 20/200 (with 20/20 being perfect visual activity). You are also considered legally blend if your side vision is narrowed to 20 degrees or less. People who are legally blind may still have useful vision.
Q: What is visual acuity?
A: Visual acuity is a measurement of your eye’s ability to distinguish the smallest identifiable letters or symbols, including the details and shape of that letter, typically at a distance of 20 feet.
Q: How do vision measurements work?
A: Vision measurements, also known as visual acuity, list the size of font you can read at a distance of 20 feet. Perfect vision is considered 20/20, which means you can identify the letter or symbol of a specific size of font (based on the Snellen chart) at 20 feet or closer. If your friend has 20/15 vision, then his visual acuity is better than yours. If your other friend has 20/30 vision, then he has worse visual acuity than you.
Q: What is myopia?
A: Myopia is also known as nearsightedness. You can see objects close to you, but have trouble seeing objects further away. More people are nearsighted than farsighted.
Q: What is hyperopia?
A: Hyperopia is also known as farsightedness. You can see objects far away from you but have trouble seeing objects closer to you.
Q: Can I do anything to reduce my risk of vision loss?
A: According to the CDC, approximately half of visual impairment and blindness can be prevented through early diagnosis and timely treatment.
Q: What causes vision loss?
A: According to the CDC, the major causes of vision loss for individuals aged 40 years and older are age-related macular degeneration, cataract, diabetic retinopathy, and glaucoma.
Q: Does my risk of vision loss increase with age?
A: Yes, your risk of vision loss increases with age. Studies have shown that the prevalence of blindness and visual impairment increases across all racial and ethnic groups.
Q: What is diabetic retinopathy?
A: Diabetic retinopathy is the leading cause of blindness among working age Americans. It’s caused by changes in the blood vessels of the retina. Diabetics should have a dilated eye exam every year to spot the condition early. Some vision supplements are specifically marketed to diabetics seeking to reduce their risk of diabetic retinopathy.
Q: What are cataracts?
A: Cataracts are a major cause of vision loss. Around 25 million Americans 40 and older have cataracts. Cataracts can impair your vision, and many people have cataract removal surgery.
Q: What are the risk factors for cataracts?
A: Research suggests that smoking, diabetes, and prolonged exposure to sunlight can all increase the risk of cataracts.
Q: What is age-related macular degeneration (AMD)?
A: Age-related macular degeneration is an eye disease that can blur your central vision. It occurs when aging causes damage to the macula, which is the part of the eye that controls sharp, straight ahead vision. The macula is part of your retina, which is the light sensitive tissue at the back of your eye that plays a crucial role in sight. AMD affects around 2 million Americans aged 50 and older.
Q: What is glaucoma?
A: Glaucoma is a group of eye conditions characterized by damage to the optic nerve. You need a healthy optic nerve for good vision. Glaucoma is typically caused by excessively high pressure in the eye. Glaucoma can be controlled by early detection and treatment, and many never experience vision loss as a result.
Q: Should I be worried about ‘spots’ floating around in my eye?
A: Spots and floaters are common. They’re typically harmless. However, if you have excessive levels of spots or floaters, or if you’re concerned about your ocular health, then see a doctor.
Q: Does working at a computer all day hurt my eyes?
A: Computer monitors emit radiation, which could theoretically hurt your eyes. However, studies show that this radiation is considerably lower than the maximum allowed limit. Nevertheless, it’s possible for prolonged computer usage to damage eyes, especially when following poor practices (not taking breaks or not using blue light filters late at night).
Q: What does 20/20 vision mean?
A: 20/20 vision means you have good visual acuity at 20 feet. It means you can read certain sizes and letters on a Snellen chart while standing 20 feet or closer.
Q: Does 20/20 vision mean perfect vision?
A: Even if you have 20/20 vision, you might not have perfect eyesight. Some people have no trouble reading information at a distance. However, they could have poor contrast sensitivity, night vision issues, or other vision problems linked to presbyopia.
Q: Can exercises strengthen eye muscles?
A: Most eye therapy techniques do not involve strengthening eye muscles. Orthoptics, however, can strengthen eye muscles if necessary.
Q: How do eye exercises work?
A: Eye exercises focus on improving vision problems by strengthening the neurological pathways between the eyes and the brain.
Q: How do vision supplements work?
A: Vision supplements contain vitamins, minerals, plant extracts, amino acids, and herbs linked to vision, eye health, inflammation, and other areas linked to vision.
Q: What should I eat to maintain good vision?
A: The best diet for vision is a diet rich with fruits and vegetables and lean protein. Your diet should also be low in saturated fats, cholesterol, salt, and added sugars.
Q: What are the best vision supplement ingredients?
A: Vitamin A, B vitamins, vitamin C, vitamin D, vitamin E, lutein, zeaxanthin, omega-3 essential fatty acids, and other ingredients are all linked to good vision in multiple studies.
Q: What’s the best vision supplement?
A: The best vision supplements include any of the top-ranked vision formulas on our list.
Q: How do I take an eye health supplement?
A: You take most eye health supplements using a capsule or tablet. You take one or two capsules per day to support eye health.
Vision supplements can support good vision in various ways. Some flood your eyes with antioxidants like lutein and zeaxanthin, helping you see more easily. Others work in more complex ways, targeting cognition and brain health to support your eyes.
