Renu is history. Its maker, Bausch & Lomb, announced that it is removing that contact lens solution permanently from store shelves Nationwide. Recently, it was determined that Renu may increase the risk of a fungal infection in the eyes. Over one hundred such cases have been reported. The CDC, FDA and Bausch & Lomb all continue to investigate. In the meantime, they don't want anybody else using that contact lens solution so it's now under recall.
