Have you ever heard bifocal glasses? If you are a glasses wearer, this name may sound familiar with you. If you are a middle-aged glasses wearer, you may wear this kind of eyeglasses in daily life. But I think this type of glasses is not so popular since the number of people who apply it is relatively small. If you Google this word, you may find abundant information about bifocal glasses which was designed by Benjamin Franklin, an outstanding science in the American history. More than 200 years ago, Franklin invented bifocals that had two distinct optical powers. At present time, a large number of manufactures have made great efforts to add new materials, more high technologies and innovative design concepts to improve the function of bifocals as well as the design of the frames. So nowadays, many people get benefits from those advanced glasses. The common sense lies in that only those middle-aged people need to wear bifocals to correct their vision problems of myopia and hyperopia. But the current trend is that teenagers are also suitable to wear this unique kind of glasses to prevent a further decline in their eyesight.
