These are the reading glasses that have built-in LEDs in the upper corners of the lens frame, allowing you to work in bed without disturbing your sleeping partner, repair a fuse during a power outage, or read in the car without inconveniencing the driver. The glasses clearly illuminate your area of focus with super-bright LEDs while keeping the surrounding area in darkness and the LEDs turn off automatically when you close the frames. Four CR1025 batteries that fit into the frame provide up to 30 hours of illumination. The optical quality frames are made of plastic; high-quality refractive lenses are available in three different strengths (+1.5, +2.0, +2.5). Includes cleaning cloth. Not available for shipment in New York. Protective case: 6 1/2" L x 2" W. (4 oz.)
