7.5 Measurement tips
• For both Sph and Cyl, measurement accuracy is ± 0.25 D in the range of ±5 D. The
cylinder axis is calculated between 1° and 180° (step 1°) with precision of ±5°. For
higher refractive errors, the 2WIN displays “high M” (myopia) or “high H” (hyperopia).
In the case the 2WIN displays “high M” or “high H” without displaying a numerical
result, 2WIN will write in the upper part of the display “n.a.” (not accessed
measurement). For big refractive errors, in the case 2WIN succeeds to estimate the
spherical power only, this estimation will appear in the upper part of the display. This
maximum spherical estimation is 15D.
• Make sure the cylinder notation (minus or plus) is set to your preference.
• During the measurement mode, please make sure that both eyes appear within the
Graphical User Interface paragraph; if necessary, slightly tilt the 2WIN.
