The LM-30 is easy to use and features automated measurement as well as data reading and storage. A nose piece for contact lenses can be attached in order to measure contact lenses in the same way as single vision lenses. Progressive lenses can be measured from the outset. The device is extremely responsive and is highly accurate in its measurements. The LM-30 can be operated either in manual mode or in automatic mode. The cylinder power, sphere power, cylinder axis and ADD power are automatically read in a progressive lens. A large LCD display enables easy reading of the measured values.
