I couldn't find a similar product in any of the local big name drug stores. All they had available were full lens reading glasses. I just needed something for reading after my cataract surgery and these are ideal. It took a couple of hours for my brain to ignore the transition line and they have worked great for the past couple of weeks. Great value for the price. I can wear them full time and not have to keep track of where I left the 'readers'. What a wonderful product.
