The easyPOCKET features a unique 50x46mm aspheric / diffractive hybrid lens that is distortion-free and extremely thin (only 3 mm). Bright illumination is provided by SMD LED technology, with bulbs that never need to be changed. Plus, with a built-in sensor, the light conveniently goes on and off when the magnifier is opened and closed. The easyPOCKET lens is protected by a strong glass-fiber reinforced plastic case that minimizes scratching. They are perfect for patients looking for a small, illuminated magnifier that is easy to travel with and use in restaurants and other dimly lit locations.
