£14.99 available on subscription

Cationorm® is different from eye drops you might have tried before. It uses ionic technology to attract its positively charged solution to the negatively charged surface of the eye, locking in hydration for longer.

Its deep-acting clinically proven formula targets all three layers of the eye and helps to:

  • Restore moisture and maintain hydration
  • Protect the surface of the eye
  • Relieve discomfort and irritation

Cationorm® is for people looking for:

  • Something different to a sodium hyaluronate-based artificial tear.
  • Long-lasting relief from stinging, itching, burning eyes or foreign body sensation.

Kind to even sensitive eyes, Cationorm® is preservative free and is suitable for everyday use and for contact lens wearers.

If you are unsure about your diagnosis, please speak to your doctor or pharmacist. Always read the label.

  1. only just started using the drops, but i`m finding it difficult to get a single drop out ,it tends to gush out and I end up wasting it.

  2. I’ve tried several dry eye products- Cationorm are expensive, but sounded good, so I tried them. I don’t find them any better than other cheaper products I’ve used, and it is very difficult to squeeze the drops out of the bottle. I either get nothing out, or drops trickling down my face. I should think anybody with arthritic hands would find them impossible to use.
    I am therefore going to go back to using the cheaper, user-friendly drops.

  3. Good drops, awful packaging, hard to squeeze when you have half bottle left. I end up wasting drops everytime. For the price I pay for these drops someone should reconsider packaging.

  4. This works brilliantly for my dry eyes. I use it 2x/day,morning and evening. Its so soothing and works well before and after insertion of my contact lenses. Having tried all the other products on the market,this is by far the best

      Hi Paula, thank you for your lovely review. Have a lovely day!

  5. Fabulous. I got these on a free trial as I work in an eye infirmary. I get extremely dry eyes and even worse on Nightshift. These relieved the soreness and pain immediately.

      Hi Tracy!

      Thank you for the great feedback, we’re so glad to hear this.

      Have a great day!

  6. Having had dry eye for over 55 years ive tried them all to no avail ! But these drops have the worst spout / tip of them all so small and stubby you very nearly poke your eye out,whoever in this day and age designed that? Also you will need to buy two bottles because one bottle will just stream down your face as it misses your eye completely so hard to squeeze and just get one drop out! Awfull small bottle and very expensive! Minor relief for two minutes then back to normal pain!

  8. These drops are so comforting for my dry eye condition. I am really impressed by their efficacy and after trying most products on the market in the last 10 yrs I’m very happy to continue using them. I have also reduced the number of drops necessary each day which is far more convenient for me.

    Jill, Wolverhampton

  9. I have used numerous products ,including preservative free prescription drops for ten years. These Cationorm eye drops are far and away more effective than any others. I am really delighted at how my severe dry eye problems have been reduced. Well worth the money.

    George, Birmingham

  10. Have just finished my first bottle. Much more relief than with any of the previous prescription drops. Very impressed,

    George, Birmingham

  11. Honestly super happy I have tried so many many eye drops, sprays and creams and and nothing worked that great. Now that I am using your product my eyes feel better and look better after a few days very happy with Cationorm I really recommend people should try it.

    J, Northern Ireland

  12. These drops feel really nourishing for the eyes. First application I was aware of seeing all milky for a few seconds after application but after using for a day this effect disappeared and my eyes started to feel a lot more hydrated and comfortable. Very good product. Would definitely buy again.

    Anonymous

  13. An excellent and effective product. I have a condition called blepharitis. These drops are the best and MOST effective that I have found. I recommended them wholeheartedly

    Deanne, Ely Cambs

  14. To be honest these drops did not make any difference and was a waste of time. They did not improve or relieve my condition so was disappointed that did not get results what you said these drops could do

    Veronica, Essex

  15. I have spent quite a lot of money on eye drops in the past, but nothing beats this one. No watery eyes make up stays on. Brilliant eye drops even though a little expensive well worth the money

    Patricia, Manchester

  16. I have very dry eyes and corneal erosion. These eye drops are very soothing and they don’t affect my vision, so no blurring after they’ve been applied. I use them 4 times a day.

    Anonymous

  17. I bought these because the marketing led me to believe they would improve my dry eye symptoms . After using for 10 days my dry eyes have not shown any improvement whatsoever.. these eye drops are like all other eye drops I have tried ..comforting for a few minutes then .., you still have dry eyes

    Jones, Cheshire West

  18. I use eye drops for glacoma which give me a lot of discomfort. I have tried various drops for dry eyes and associated problems but nothing worked. My consultant gave me Cationorm to try and I have to say it gives me far more relief than anything else I have tried. I shall be ordering more shortly.

How it works

Cationorm® is the first and only eye drop that uses ionic technology, for long-lasting relief.

  • It uses ionic technology to lock its positively charged formula to the negatively charged surface of the eye.
  • As a result, drops may not need to be reapplied as often as with alternative eye drops**.
  • Our eyes’ protective outer tear film is made up of oily, watery and mucus layers and Cationorm targets all three with its advanced triple-action dry eye science.

**Compared to alternative eye drops which use a sodium hyaluronate formula


Woman applying eye-drops

Easy application

Cationorm is suitable for everyday use and for contact lens wearers. Use it for relieving symptoms of dry eye as well as dry eye symptoms caused by:

  • air conditioning
  • pollution
  • travel by plane
  • working on a screen
  • refractive surgery
  • contact lenses wear, etc
  • meibomian gland dysfunction

For best results, apply 1 drop in each eye 1 to 4 times daily:

  1. Wash your hands.
  2. When you are using the eye drops bottle for the first time, remove the tamper-evident ring of the cap by pulling off the prominent strap.
  3. Open the bottle by gently pulling the cap.
  4. Grasp the body of the bottle between your thumb and forefinger.
  5. Avoid any contact of the tip of the bottle with your fingers.
  6. Tilt your head back.
  7. Gently pull down your lower eyelid and look up.
  8. Hold the bottle above the eye and place the back of your hand on your forehead.
  9. Gently squeeze 1 drop in the eye and blink several times.
  10. Do not touch the eye or eyelashes with the tip of the bottle.
  11. Put the cap back on the bottle after each use.
  12. Store the bottle in the box when you are not using it – use Cationorm® within 3 months after the first opening, then replace it
