The product is excellent in relieving redness in the eye as well as swelling. Upon usage, the product will discharge mucus from the eye showing that the product is working. I have only been using the product for a couple weeks now and have noticed a big difference in the appearance and clarity of the eye.
My 11+ year old Shih Tzu is starting to get cataracts, her eyes have a light blue tint, but she can still see good. I was using Sensodyne (for humans), then started using C-bright last year, which is especially for dogs and cats. It works WONDERFUL! I could tell her eyes are clearer and a lot less red. I first purchased it from another on-line company which quit selling it (their loss). I did a search for C-Bright and found this wonderful company. Very good prices and ships very fast. I ordered and received it 2 days later. You cannot go wrong with this product, or this company.
My GSD has Pannus and this helps to keep the eyes lubricated. It works great combined with the antibiotics she requires daily for the redness & swelling that occurs because of the disease.
