The Foster Grant® Charlsie Multi Focus™ Blue Light readers deliver the functionality of Multi Focus™ readers with the added benefit of blue light filtration. These stylish cat eye frames feature three different strengths in one pair of glasses, making them perfect for reading, using a computer and interacting. They also filter 30% of potentially harmful blue light.* A contemporary case is included to protect your readers when not in use.
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.
*Potentially harmful blue light refers to the 415-455 nanometer range of the visible light spectrum. The percentage represents the average amount of potentially harmful blue light filtered at 5 nanometer increments in this range. Covered under U.S. Pat. No. 8,360,574. Other U.S. and foreign patents pending.
For every pair of Foster Grant® glasses you buy, a pair of reading glasses will be donated through Specs for Specs™ to people in underserved communities around the world.
