Primary outcomes

  1. Reading Speed

    Time frame: Between Year 1 and Year 2 of the WS10246 study, representing an average timeframe of 1.5 years into the parent study.

    Reading speed (mean words per minute) collected using the Wolffsohn Research iPad OptomCentral App

Secondary outcomes

  1. Binocular distance high contrast visual acuity (VA) through the lens periphery

    Time frame: Between Year 1 and Year 2 of the WS10246 study, representing an average timeframe of 1.5 years into the parent study.

    Measured to the nearest letter using a standard ETDRS chart at 4 meters.

  2. Binocular photopic near contrast sensitivity function (CSF)

    Time frame: Between Year 1 and Year 2 of the WS10246 study, representing an average timeframe of 1.5 years into the parent study.

    Evaluated at 40 cm using the iPad OptomCentral App across various spatial frequencies to calculate the Area Under the Log Contrast Sensitivity Function (AULCSF).
