Description:

The Topcon LM-8 is a traditional, manual lensmeter engineered for accurate measurement of eyeglass and contact lens prescriptions. It precisely measures spherical, cylindrical, and prism powers using clear internal mires and an illuminated protractor scale. Its cross-line target and green LED illumination simplify the detection of lens axis and vertex powers from -25 to +25 diopters (0.125 D steps). Prism diopter readings extend to 0–20 Δ (1Δ increments), and the built-in lens marking system enables precise lens alignment and layout. With robust metal construction, intuitive controls, and a compact 6.3″ × 16.5″ × 10.4″ footprint, the LM-8 is an industry-standard choice for ophthalmic laboratories, optical dispensaries, and optometry practices.

Economic Advantage:

The LM-8’s hallmark lies in its simplicity, durability, and precision, minimizing both initial investment and ongoing maintenance. Its manual design eliminates dependence on software updates or complex calibration, significantly lowering long-term operating costs. Quick, intuitive operation allows faster patient throughput and fewer measurement errors, improving practice efficiency and profitability compared to digital or automated systems. For many labs, this proven reliability makes the LM-8 a cost-effective benchmark instrument.
