LEM-3 1.75x Ultra Lightweight magnifying eyeglasses. These are very light folding magnifying eyeglasses. The portable size and ultralight weight is ideal for short use inspection when a bit more magnification is needed to do the job in a hands free platform. They are made of 100% optical grade acrylic, and are so light you might forget your wearing them. The light weight comfortable fit means they must be handled with care and they are not designed as full time magnifying eyeglasses. MADE IN USA
