The Topcon LM-8 is a classic lensmeter model which combines high magnification optics with an excellent wide field eyepiece to enable easy measuring of lenses with a low range cylindrical power. The lensmeter is powered by battery and features an LED illuminated target for brighter, glare-free viewing. The Topcon LM-8 benefits from a new cartridge type marking device for improved marking, as well as a redesigned eye-piece which provides less shading effect and is less fatiguing to use. It uses a crosshair style traget and has a built-in prim compensator. The Topcon LM-8 lensmeter makes contact lens measurement much easier for the user.
