Couldn't load pickup availability
Portable manual lensometer (focimeter / vertometer) for measuring the vertex power of spectacle lenses, sphere, cylinder, axis, and prism. Direct scale reading system with corona target, ±20 D sphere range in 0.25 D graduations, 0-180° axis rotation, prism diopter compensator (0-180-0 with 5 D graduations), holds lenses 30-80 mm diameter, 0-90° adjustable tilt for progressive lens neutralization. Dual power: 2× AA batteries OR 220V AC. Compact case for portability. $349 direct, versus $1,200-$2,500 for Nidek LM-1000 / Topcon CL-200 / Reichert AL-500 auto-lensometers.

- University optometry teaching: student practice and skills exam
- Community and rural eye clinics: spectacle prescription verification
- Vision and cataract camps: mobile Rx verification for patients receiving used donated glasses
- Insurance and workman comp verification: documenting current Rx for records

FAQ
How does this compare to auto-lensometers?
Auto-lensometers (Nidek LM-1000, Topcon CL-200) give push-button digital readouts, faster for high-volume dispensing labs. Manual lensometers require the operator to align corona target lines manually, slower but full clinical accuracy at 15-25% of auto-lensometer cost. For NGO vision camps, community clinics and low-volume practices, manual is the value-tier winner.
Can I measure progressive addition lenses?
Yes with the 0-90° tilt adjustment, required for progressive lenses since distance zone and reading zone Rx are measured at different tilt angles per manufacturer.
Battery or AC power?
Both, 2× AA batteries for portability (NGO vision camps, mobile clinics) or 220V AC for permanent bench mount in a dispensing lab.
