Best suited for narrow faces.
This innovative Multi Focus™ lens technology means no more taking your readers off and putting them back on to see things clearly at different distances. The bottom third has the highest strength (and the power you choose) for reading, the middle third has a slightly reduced magnification for computer use, and the top third has about half the strength of the bottom, for clarity when interacting with someone nearby (sitting across a desk, for example). The magnification is strongest on the bottom of the lens (what you use for reading), the middle portion is slightly less than your reading power, and the top portion of the lens is half of your reading power.
