Measurement & records

A clearer workflow for everyday lens checks.

Choose a lens-specific mode, follow the alignment guidance and keep the results ready for review.

01 / Lens modes

Select the right measurement mode

Choose normal-lens, progressive-lens, contact-lens or automatic-identification mode. Contact-lens measurement uses the dedicated lens support.

02 / Progressive lenses

Locate distance and near zones

Directional guidance helps position a progressive lens for distance and near readings. Review the addition power or switch to the near-power display.

03 / Result capture

Automatic L/R and result memory

Enable automatic left/right switching when changing lenses. Stable readings can be stored automatically, including distance and near results in progressive mode.

04 / Optional printing

Keep a printed measurement record

An optional thermal printer produces measurement records with a configurable date format and company header. Specify the printing configuration when ordering.

Center, mark and compare lenses.

The 5.6-inch color display and graphical centering target support lens positioning before marking. A selectable UV/blue-light mode supports transmittance comparisons between lenses; keep the measurement area away from strong ambient light.
