trifocal

These are glasses with three separate zones of focus. The top is set for distance, the middle for intermediate (such as computer distance) while the bottom is optimized for reading. While effective, many people don’t like having this many lines on their glasses.  For these people, a progressive lens (no line bifocal) may work. Purchasing separate computer glasses may be another option.
