Outcome

Type Measure Description Time frame Safety issue
Primary Distance LogMAR Visual Acuity 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%) 7 days post wear
Primary Near LogMAR Visual Acuity 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%) 7 days post wear
