    Hello Jim, I have received your very generous replacement and a great big thank You for reaching out to me. You have gained a customer for life and not only that but the OcuPhase is working. My vision is clearer as there are less floaters.
    Thanks again

    I purchased these eye drops because I had dry eyes and also was recommended to have cataract surdery. I decided to use these drops daily. My dry eyes problem is resolved. I have not been to see the doctor to see if my cataract progression has stopped.
    I have a problem with the bottlets . Even if I puncture with the cap supplied there is no guarantee that the eye drops will come out the next time I use it. May be a piece of plastic blocks the opening. It will help if you could improve the design!
    Thank you

    OcuPhase Eyedrops

    My husband had eye surgery and the surgeon instructed him to put drops in his eyes every day to keep the tissues moist. These drops are so clean compared to others available over the counter.

    I received your product and after the first vial I saw improvements in the floaters and I am thankful. However I opened the second vial and placed it in the fridge
    When I went to use it next I noticed that the vial was laying flat. I picked it up and it was half empty and there was liquid under it. I tried to place it upright but it was difficult to do so as the bottom of the vial was not flat so I placed it between some jars and left. Next morning I came and it was again flat as someone had moved a jar. It was completely empty. I had made sure to fasten the lid securely. I think that the seam may have busted in an area where there seemed to be a bulge. I am very disappointed at the outcome seeing I pay in Canadian dollars which work out to be expensive. I noticed that others had various problems with packaging. You really need to fix this as I am now hesitant to make a purchase as a result

    Perfect, except for the new packaging

    The OccuPhase product works great for me and I have used it for years – the product itself gets 5 stars. I have chronic dry eyes and other vision issues that come with aging and computer use that cause eye strain. I find that using this product before bed really works during the night to help restore my eyes.

    I was very disappointed with the last order I received that contained the new packaging. It took days of trying to get even one drop out of the bottle and it is very difficult to use and the hole sometimes closes up even after it has worked before.

    Please fix the packaging to make this product easier to use, like before. I will reorder and try again, but if the issue is the same, I may need to look for a different product.

Suggested Use: For general preventive use, the recommended amount is 1–2 drops daily. Those with eye problems may want to use 2 drops twice daily or as needed.

OcuPhase also contains 1% N-acetylcarnosine, a naturally occurring antioxidant and antiglycating agent that helps protect the active ingredients from glycation. OcuPhase also contains ophthalmic lubricating agents to combat “dry eye” and other forms of eye irritation. Each box contains two vials containing five milliliters each.

Each package contains two resealable vials containing a total of about 200 drops, which allows for only a small amount of product to be exposed to oxygen at a time. Unopened vials can be stored in the refrigerator to extend shelf life.


  • If you experience eye pain, changes in vision, continued redness or irritation of the eye, or if the condition worsens or persists for more then 72 hours, discontinue use and consult a doctor.
  • To avoid contamination, do not touch tip of container to any surface.
  • Replace cap after using.
  • Do not use if seal is broken.
  • If solution changes color or becomes cloudy, do not use.

Good nutrition is a key element of preventing numerous age-related issues, including the health of our eyes. As we age our eyes become more susceptible to a host of challenges that can lead to irritation, discomfort and changes to vision. Colors may be dulled or distorted, and there may be an annoying halo of light around bright objects, causing a glare effect.

Applying lubricating eye drops several times a day can help to alleviate discomfort. Additionally, a number of nutrients have been shown to benefit eye health and good vision. One of these, carnosine, is a dipeptide consisting of two amino acids (alanine and histidine) connected by a chemical bond. Based on research performed mainly by Russian scientists, it is believed that carnosine’s antioxidant properties support healthy vision by inhibiting a chemical process called glycation.

Glycation leads to deleterious chemical complexes called AGEs (advanced glycation end products) that result from common but undesirable reactions between blood sugars, such as glucose, and proteins in many parts of our bodies, including the lenses of our eyes. The sugar-protein complexes become chemically cross-linked and degrade cellular functions. The aptly named AGEs are thought to be an important factor in the aging process.

Carnosine eye drops have been shown to aid in delaying vision senescence in humans by restoring the natural structure of proteins in the lens.


N-acetylcarnosine (NAC), like its parent compound, carnosine, occurs naturally throughout the human body. Both compounds are found primarily in the heart and skeletal muscles (the word carnosine is derived from the Latin word for flesh) and in the brain. Carnosine was discovered in 1900 in Russia, and it is in Russia that most of the recent research on the N-acetylcarnosine derivative has been carried out. Research with N-acetylcarnosine, as with carnosine, demonstrates that it is effective for improving transmissivity of light through the lens.

The structural difference between NAC and carnosine is that one hydrogen atom in carnosine replaces an acetyl group (CH3CO-), and this substitution occurs at a nitrogen atom. An important chemical difference between carnosine and N-acetylcarnosine is that carnosine is relatively insoluble in lipids (fats and fatty compounds), whereas N-acetylcarnosine is relatively soluble in lipids (as well as in water).

This means that N-acetylcarnosine may pass through the lipid membranes of the corneal and lens cells more easily than carnosine, and may thereby gain access more readily to the cells interior, which is primarily aqueous. There, the N-acetylcarnosine is gradually broken down to carnosine (and, perhaps, to histidine), which then exerts its beneficial effects.


Carnosine and N-acetylcarnosine eye drops appear to be a safe, effective means for supporting eye health, comfort and quality of vision in aging humans.
