These are a good idea but there are some issues. First they scratch easily. Second they are just like stickers for the bifocal part and those stickers are also tinted, so looking through the bifocal part its much darker than the rest of the lens, which is less than ideal. And lastly they are an odd shape, they don't look that much like the picture. I am using them but I wouldn't buy another pair.
