Earth Clinic's most popular natural remedy for conjunctivitis ("pink eye") is apple cider vinegar. Dozens of our readers have reported this cure. Most have been surprised at how quickly this treatment works!

How to Use Apple Cider Vinegar for Conjunctivitis

You must use a very diluted solution of apple cider vinegar and water. Add just 1 teaspoon of apple cider vinegar to 1 cup of water. Use a cotton ball to apply the mixture to your closed eye (some will get in to the eye and that is fine) three times a day. Always use a fresh cotton ball for each eye, and a fresh cotton balls for each treatment. Both eyes should be treated, even if only one appears infected.

Ideally, used distilled or filtered water and raw and organic apple cider vinegar. Raw vinegar has "the mother," which makes the vinegar cloudy in appearance. There will also be a stringy substance (the mother) in the vinegar. This usually settles to the bottom of the bottle. Just don't shake the bottle of vinegar before you pour out your teaspoon worth to add to the water.

Most people find that this treatment stings some when you apply it but that the discomfort does not last long.

Usually the infection clears up in a day or two with this treatment. However, even once you are symptom free, continue the treatment for a couple more days to make sure the infection does not return.

Pain swelling redness constant puss running out. finally thanks to God I looked on earthclinic. The only vinger I had was the big cheap. Bottle of distilled Apple Cider Vinegar. I put a tablespoon in a cup of warm water. clean both eye eyelashes got out all gunk and the dropped about six drops in both eyes ..augh the burn was something else and my eye just oozed out puss and gunk ..

I clean them again and repeat until gunk slow down and then oh my gosh sweet relief and eyesight return.. first time in over a month with no eye pain. I repeated this every hour until bed time I woke a couple times during night and would repeat clean drops clean drops until eyes were clean and fresh. I woke this morning swelling gone.

You hit it hard, again and again, once or twice a day ‘ers will find a much slower result! —remember this in the natural world.

I was a big advocate for putting drops of Apple Cider Vinegar in my eyes mixed with distilled water. I had cataracts that is why I did this. I just had a doctor inform me that I had a tear in my Retina. He had to do a laser in the back of my eye. No more apple cider vinegar mixed with water for me!!!

Apologies in advance. This is a bit long, but I just have enjoyed the benefits of this remedy and am thrilled to have this in my self-care medicine cabinet!

I just thought I'd add my two cents because it's been a life-saver for me. It's my go-to whenever I have gritty or dry-eyes or the occasional pink eye from wearing contacts too long (admittedly sometimes falling asleep in them too often). I first found this remedy here because I was desperate. Back in the days of living with no health insurance, too many all-nighters and being a dry eye having, contact lens wearing, cosmetic lover. While working one of my most stressful jobs, I came down with a combination head cold and eye infection that forced me to go to the doctor. I was put on a course of about 10 days of antibiotic eye drops ($60 for a tiny bottle not including doctor visit). I tossed my eye makeup, contacts, cleaned all my brushes and followed the prescribed cleansing with warm water/cotton balls and eye drops and saw it improve. Then the next week it came back—I think it hadn't completely gone away. I went back for a second bottle of eye drops. It didn't work because it seemed I needed to use something stronger or use it longer. In any case, I could see this being a recurring issue due to my lifestyle.

I luckily found this site, ACV remedy and it's happy users. I tried the method of lightly tinting about 1/4 cup of water with ACV, gently wiping with one soaked cotton ball per eye, discarding and saturating each eye with fresh soaked cotton balls (letting a few drops get into each eye). It stung slightly and caused my eyes to tear. By the end of the day (3 applications later), I saw less redness, swelling and gunk. By the third day, there were no more symptoms. I continued a couple more days, but only 2x a day to be sure it was gone and no contacts or makeup for a whole week. I'm so grateful this was shared on here—best ever remedy for me! I even occasionally use it for maintenance to flush out my tear ducts when they're irritated or have been feeling drier lately. I haven't had to use artificial tears anymore.

Please be sure to dilute! As other users have noted, you can injure yourself if you're not careful (it's an acid). If in doubt, it's better to err on the side of caution. I tested it with a very diluted solution at first and got a feeling for what I could tolerate. But, I noticed for me, 1/4 tsp ACV to 1 cup water is tolerable and resolved pink eye nicely over 4 days or so.

I wasn't wrong risking my eyes on this! My infection started on a saturday and people say that this usually last for a week and I was thinking I cannot afford not to go to work that long :(, so I saw from the web (not this yet) that ACV can cure, but I was so hesitant because I cannot imagine putting vinegar to your eyes! But I don't think that it will be much painful compared to having shampoo in your eyes... so I took the plunge and did it.. and the next day, all the symptoms went away!! I was wow! Holy ****! The people around me was like! What did you do?? how is that possible! OMG.. ACV totally Rocks!!

I was thinking about the sting of the very well known eye drops Rx for pinkeye, call Vigamox, it hurts and stings as bad as ACV.

Long ago, medicine was in tea and powder form and people just took it as they needed to, now we are all spoiled, no bitter pills or powders, sweet coatings on our pills make them easier to swallow but do just the same as the old bitter potions our great grandparents had.

This is a warning for anyone with eye infections. Please Do Not use apple cider vinegar in or around your eyes. I had an eye infection, looked online and saw that claims were being made that it was okay to use this in your eyes (and that it cured infections). I made the mistake of doing so, it burned my eyes (not permanently) and I was so scared that I went to Urgent Care and then an Opthamologist. This is an acid and should never be put anywhere near the eyes. There are many posts saying that this is fine. It's not and could be very dangerous. Your eyes are precious - if you have a problem, go to an eye doctor.

Maizy, people mean VERY diluted, of course.

Replied by Alan

Diluted is only way to use it, nothing more than a mild sting, in used it in a eye bath, ie flooded my eyes, maybe I teaspoon in a cup of water

Cured my eye issue in one day

Did u use it alone? Full strength? If so, no wonder u had an issue.

Replied by David

Yes, it must be VERY diluted, like 1:10 ratio of ACV:Water. Like any medication or treatment, incorrect usage can result in problems. Some people have died from Paracetamol because they didn't READ the instructions and dosage limitations.

To be clear you are NOT supposed to use Apple cider vinegar undiluted. You MUST use roughly half a teaspoon in at least an 8oz cup of water. Yes it is an acid, but when using any medicine (in this case ACV) you will have side effects I.e. slight burning. If you use visine for example your eyes will burn as well for a moment. It's important to do careful research and not just take anyone's information. In this case reading multiple articles about to pros AND cons of using something will tell you about the risks involved. So anytime anyone wants to try something new (even if it is an FDA approved drug) you should search for side effects or people that give reasons not to use it. That's when you can make a sound diction on whether home remedies are safe enough to try. Dosage is everything. Salt is not only safe but needed for our life, but someone that in theory has never learned that might eat enough salt to have a heart attack. Moral of the story the devil is in the details.

I was really amazed at the results using apple cider vinegar, filtered water, Himalayan salt, and black tea. I used 1 1/2 tbsp water, 1/4 tsp ACV and Himalayan salt, 1/2 tsp of black tea. First warm water and add salt. Stir to dissolve salt. Add ACV and tea. Stir. I used small 1inch square pieces of paper towel soaked in solution to wipe eye from corner to outside in one stroke and discarding each piece of paper towel. In using same method, I gently wiped several times, allowing solution to enter into the eye. Make sure you use paper towel only once for each wipe as not to reinfect eye. It helps to have a tissue under eye to catch dripping solution. Wash hands in between, as not to infect other eye. I applied same technique on other eye to ensure both eyes were treated and not infected. I got immediate results. Solution does slightly burn on first few wipes only. You can dilute solution to your preference. I used this technique twice a day for 2 days. Both eyes stopped itching, redness and swelling disappeared, and eyes became clear on the first day. This solution is a miracle. Allergy Meds, and eye rinse did nothing to stop condition, but this worked.

Thank you for sharing this recipe! After getting pink eye for the 3rd time in 3 weeks, I was desperate for something to work and this did!!! The first and second round of pink eye I treated with vigamox, with no success, and now dealing with a lasting side effect chronic dry eyes. This treatment above worked within 3 days, although it was painful I couldn't take the pink eye any longer Thank you again!

Viral Conjunctivitis: I have been a believer in non toxic stuff for a few years now and I used to swear by how quickly honey was for my irritated eyes that I get every now and then and I must say After reading all the reviews I remembered that I had a full bottle of ACV with the "mother" in it and WOW is all I can say almost instant relief was little gritty at first but after a few eye washes and a little drop of it in my eyes I can tell it is working. Started just last night and My eye went from all red and irritated to just little red at bottom of eyelid. Fantastic and so glad I found this site. Thanks to all!!!! ..

One question I do have if you put mixture in a eye dropper with a cap is it still suggested to do fresh batch after 24 or 48 hrs?

My eye has been bothering me all afternoon...itchy, goopy, etc. I came on this site and saw that ACV was the most popular cure and I tried it.

I used a half cup distilled water with a half teaspoon ACV and applied with a cotton ball. Like some of the other posters did, I first lightly rubbed it on my closed eyelid and then squeezed a bit out so it would run in my eye. And yes, it did burn a bit, but not long. But my, oh my! The relief was instant! The itching, blurring and running goop was gone. I have done it twice in an hours time, and will again before I go to bed.

I know it's not healed yet, but I bet it will be by the end of the day tomorrow (taking the mixture to work).

I had watery eyes all throughout the day and into the night. I woke up in the middle of the night with a pressure sensation and inability to keep eyes open without discomfort. Looked in the mirror to find one eye extremely red; the other only mildly red. I knew immediately that this was viral conjunctivitis, as my mom had been suffering from it for about 5 days. We had done everything to prevent transmission, but it still happened and I was panicking, as I needed to go to work in the morning.

So I desperately began searching for a home remedy, and found the apple cider vinegar remedy on this site. It appeared to be the most popular one, so I gave it a try.

I warmed 1/2 cup spring water, added 1/2 tablespoon apple cider vinegar (MUST be raw, "with the mother"), and stirred for a few seconds. I dipped a cotton ball (one for each eye) in the solution, and with eyes closed, dabbed the solution at the inside and outside corners of each eye. I also squeezed the cotton ball a little, to allow some of the solution to flow over my eyelashes. It didn't burn until I opened my eyes. The burn was significant, but not very long-lasting.

I laid down on the couch with my eyes closed until 5am, at which point I got up to start the process of calling in sick. Before making any calls, I checked my eyes in the mirror....... to my EXTREME SURPRISE, the redness was COMPLETELY GONE. I was in disbelief. I went to work, and then repeated the apple cider vinegar treatment again before going to bed that evening. I did it again the next morning, just to be safe, and my husband did it as a precautionary measure as well. It worked. Our daughter didn't get it, either. My mom had tried colloidal silver and raw honey; none of which worked for her.

I highly recommend apple cider vinegar at first sign!!!!

Yesterday morning I woke up with a bad case of pink eye. I get pink eye a few times a year so by now, I know when I have it. Neither of my parents were in town so I couldn't go get medicine And I had a rather large event happening that night, thankfully I found earth clinic. I tried the ACV treatment and although it burned like hell, it worked its magic and by that night you almost couldn't tell I had ever had pink eye. Before I put in the ACV I would rinse my eye out with black tea, and treated my eye about 3 times. Today I keep treating it just to make sure it's gone but I am extremely thankful I found this site, it saved me!

It's very odd that you would get pink eye several times a year, I've had it once in my life, and it's something that is contagious so, you would have to pick, it up from someone. Do you wash your hands frequently? Do, you touch your eyes a lot? I'm thinking you must because that's the only way you can catch it. It's isn't something that's airborne and goes into your eyes.

I have had viral pinkeye (specifically the EKC virus) 3 times in the last 4 years. Episodes last roughly 10 months and let me tell you, it's devastating. I'm convinced that being that it is a virus, it never fully goes away and it just lies dormant till something triggers it again. I'm going to try ACV. I'm at my wit's end as this affects my family life, job, and ability to be social.

This is from the Bragg's apple cider vinegar book: 1/2 tsp Apple Cider Vinegar to 4oz of distilled water. page 71 "Apple Cider Vinegar." I boiled the distilled water, let it cool, add acv, then place in sterilized dropper or eye cup and submerge affected eye. Cleanse 2 to 3 times daily.

I've had viral conjunctivitis for a couple month's now. My doc said there was nothing out there that would "cure" it and to just let it run it's course - up to 3 months!

I just did the 5:1 ratio with ACV and it burned like hell for about 30 seconds - and wa-la! My vision cleared up - been blurry ever since I contracted this. And my redness went down considerably. I am so thankful I found this remedy!!

I had Pink eye and I had just changed Drs. So, my new Dr. would not prescribe me anything. Well, I did the ACV and water four times a day. I also used the green tea bags twice a day to help with the soreness and I wash my hands a lot and I cleaned my glasses with the ACV, to make sure I would not get it again. It took a little over a week, but I think it took that long because I look at a computer working, at least 7 hours a day. I LOVE this website.

Yes! it works!

My lil bro had an eye infection, I don't know what kind, maybe pink eye? It was really swollen. So I got the ACV the top part, ( not shucked, stable, so that I do not get the mother, and a mixed in a bit of drinking clean water in a mug, then maybe 40 acv, 60 water. Try your own, the more ACV the more the burn, but the more the potency.

We put it in an clean drop dropper, and I applied to his eye. Yes it stung, muaaahahah. But he took it like a man. I told him to apply twice + a day. It took off in like 4 days.

He did not have to spend money on going to the Dr. :) , and I got to experiment with his eye :). It was a win win lol. I have to say I was a bit unsure about it. Because well, its the eye.... But not anymore, if I ever have an eye infection, I will not hesitate to put it on my eye. :)

If your are scared, you can apply to out lid, I guess.

ACV rocks! I love you Earth Clinic <3

Reply to this if it works for you

I had gotten some water splashed in my eyes while teaching a student how to wash their face... anyway.... my eye started itching the next day. Then two days later both eyes were goopy, swollen and itchy.... I have followed the instructions on this post and have been using the Apple Cider Vinegar for two days now. My eyes are still a little itchy day two however when I woke up this morning they weren't as goopy, swollen or itchy as the days prior. I see a big improvement. Also the eye that originally got splashed with water is no longer pink. I will continue to do this the rest of today and tomorrow so it will be a full 3 days like several people posted. I am so happy to not have had to go to the eye doctor and spend money I don't have and get antibiotics! Thanks!

I woke up one morning with pink eye. In a glass of water in put enough ACV to tint the water and placed drops of it into my eye. It was cleared up completely within two days.
