I have used Novus products for years. Novus 1, 2 and 3 are excellent products for removing scratches from plastics and acrylics. They work extremely well and probably the best products on the market for refurbishing plastics. So, when I saw that they offered a eyeglass lens cleaner, I was excited to try the product.While the product works very well, I don't really see any performance improvement over the cleaners that I can pick up at my local drugstores. Additionally, the Novus lens cleaner is twice as expensive and only 1/3 the size of the products that I get at my local drugstore. While it works well, the Novus name isn't work twice the cost at a third the size. Economically, I can't really recommend this product.
