You are talking about the rigid lenses, right? I really want to try them. The soft ones 'worked', but made me crazy. Very distracting with the co-mingled near and far regions, I could not ignore the blurry areas. And on top of that they wanted me to have one optimized for distance and one optimized for reading. Not good, I need symmetry. Just wearing one lens was better and cheaper than the soft multifocal, but still very distracting.I did decide to go try bifocal contact lenses. Nobody at my eye center had ever tried them and my eye doctor told me that the bad rap on them is they are uncomfortable. Well I have had them for two months and love them. They are very comfortable, I cannot even tell I have them in. I can see distance and read with each individual eye.
