I continually try to buy the 12 oz Equate Multi-Purpose No Rub Saline Solution. It's in stock and then out of stock - very annoying. Walmart is never out of stock. So when I saw the 4 oz size available, I misread it and bought three, thinking it was the 12 oz size. Totally my fault. It was clearly described. I'm just annoyed at the poor service Walmart is affording its customers who want the 12 oz size. They evidently refuse to carry it, probably under some pressure for name brand vendors.
I think saline is saline pertaining to the solution used to rinse soft contact lenses.\n\nI use this to rinse after storing in the Equate Multipurpose Solution. Just before insertion, I will rinse the lenses well this this saline solution. It seems to get any residual disinfecting solution off the lens that might cause irritation.\n\nThe Multipurpose solutions tell you that they're okay to rinse with but I believe this is a better solution to use for rinsing as it not only costs less but, for me, causes less irritation to the eye as it is rinsing all the disinfecting agents off the lens before insertion.\n\nThe only drawback is that you have to keep two bottles of solution around.\n\nAs another reviewer stated, in the stores, you can buy the two-pack that makes the cost of one bottle less than $2.
