As we get older, we often have difficulty focusing on objects close-up and at arm's length. It happens to us gradually as our eyes lose their ability to focus close-up. By the time we reach our mid-forties, we have to strain to read newsprint or a menu in a dimly lit restaurant. Ninety percent of people older than forty-five need some type of vision correction. To correct presbyopia, traditional solutions have included reading glasses or bifocal lenses.
Progressive lenses offer a more effective solution.
And, progressives are more convenient - unlike reading glasses, they can be left on for all your daily activities.
