Multi Focus™ Troy reading glasses feature a classic, square frame shape made out of durable plastic. The elegant design and delicate hinge studs are what really makes this pair of Multi Focus™ reading glasses stand out. With 3 lens strengths in one pair of reading glasses, Troy is perfect for reading, computer use, and interacting. Adjustable nose pads provide a custom fit for all day comfort, while scratch- and impact-resistant lenses help keep your readers looking new and your view clear.Multi Focus™ reading glasses feature three strengths in one lens. 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). 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.
