Best suited for narrow faces.
These comfortable frames offer spring hinges, an anti-reflective lens coating, and scratch-resistant lenses.75 The McKay Multi Focus™ Reader has three different powers that allow you to use them for reading, computer use, and interacting. 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).
