What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Near visual acuity assessment with OdySight versus with near visual acuity chart
Time Frame: 1 day ( During evaluation visit)
To assess the equivalence between a smartphone based evaluation of near visual acuity with ODYSIGHT (NVA module) and a standardized method (Sloan ETDRS near vision letter chart).
1 day ( During evaluation visit)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Near visual acuity assessment with OdySight versus with ETDRS chart
Time Frame: 1 day ( During evaluation visit)

1 day ( During evaluation visit)

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
