Distance LogMAR Visual Acuity
大体时间:7 days post wear
|
Distance time controlled LogMAR (Logarithm of the Minimum Angle of Resolution) Visual Acuity was carried out binocularly, at 4m (meter) under 250 cd/m^2 and 2.5 cd/m^2 (candela per square meter) luminance.
The test was presented under the two conditions; High luminance (250 cd/m^2) High Contrast (90%) & Low Contrast (10%) and Low Luminance (2.5 cd/m^2) High Contrast (90%)

Near LogMAR Visual Acuity
大体时间:7 days post wear
|
Near time controlled LogMAR Visual Acuity was carried out binocularly, at 4cm under 250 cd/m^2 and 50 cd/m^2 luminance.
The test was presented on under the two conditions; High Luminance (250cd/m^2) High Contrast (90%) & Low Contrast (10%) and Low Luminance (50cd/m^2) High Contrast (90%)
