Often people who need assistance with reading and distance all the time wear these lenses. They offer clear vision at all focusing distances from far away to your computer to your close up needs. These are often used in conjunction with a set or two of task specific glasses. For example, this could be a separate pair of single vision readers to make evening reading and close up hobby work more enjoyable. It could also mean having a pair of glasses just for office use, which offer a much wider field of intermediate and close up vision, making working at the computer all day long much nicer. For the golf enthusiast, we can even make speciality glasses for you!
