Bausch & Lomb Contact Lens Solution

I just hung up with Bausch & Lomb. I was down to my last unopened bottle, and was very worried this had been discontinued. I used to purchase through Amazon subscribe & save, but A canceled my subscription, said product was no longer available. I am happy to report that B&L says it is NOT discontinued, but had been on back order for quite some time. It is now off back order, and available. The days of $5 a bottle are gone, but for me, using 3 drops per lens per night, a bottle still goes for ages. Very good value for keeping lenses as impeccably clean as possible. On another note, I read a recent in-depth scientific study comparing hydrogen peroxide systems (like ClearCare) versus multipurpose systems (like Renu). The peroxide systems were (statistically significantly) superior for lens cleaning, but the study emphasized that it is essential not to use the cleaning jar with its neutralizing disc for more than 100 uses. The left over peroxide is an eye irritant, and the disk's ability to neutralize declines with each use. In the good old days -- disks sold separately -- I used to change my disk once a month. Not possible now. I am thinking I may quit buying ClearCare at Costco, because you get two 16-ounce bottles, and two disks, so the disk is in use for one-third more uses compared to the regular "drugstore" packaging of one or two 12-ounce bottles with one disk per bottle. For a slight savings on the whole regime, I use Target brand "sensitive eyes" saline at night for my cleaning/rinsing, but use Purilens preservative-free saline in the morning for rinsing lenses from the hydrogen peroxide jars and before putting in my eyes. I figure this is doing a relatively good job of keep preservatives out of my eyes. And of course, I am still in mourning over the discontinuation of the once-a-week enzymatic pills for use in the jar. I want to wear contacts, but I want them to be as clean as I can possibly keep them! Wow, quite a long way from the old days when I started wearing contacts at twelve years old... you put your lenses into a small case, and the case into the top of a small plug-in boiler, then added distilled water, and cooked your contacts clean. This probably was a superior system, and no trouble at home. On the road it was a different story, I remember hauling distilled water around Europe on one trip!
