While wearing bifocals, you may realize you must tip your head slightly to use the intermediate-computer or reading portion of the lens. This is fine for most general situations, but if you want to read or use your computer for a long period of time, this head-back posture can cause discomfort and fatigue. The computer-reading zones are also quite limited. Often a pair of single vision reading glasses or multifocal computer glasses are a much better solution for prolonged computer - reading and other detailed near vision tasks like sewing needle work.
