Outcome Measures
Primary Outcome Measures
- Near visual acuity assessment with OdySight versus with near visual acuity chart [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).
Secondary Outcome Measures
- Near visual acuity assessment with OdySight versus with ETDRS chart [1 day ( During evaluation visit)]
To assess the relation between the ETDRS visual acuity at a 4-meter distance and near visual acuity evaluated with ODYSIGHT (NVA module)
Other Outcome Measures
- Contrast sensitivity assessment with OdySight versus with Pelli-Robson [1 day ( During evaluation visit)]
To compare the smartphone based evaluation of the contrast sensitivity with ODYSIGHT (contrast sensitivity module) and a standardized method (Pelli-Robson chart)
- Scotoma/metamorphopsia detection with OdySight versus with standard Amsler grid [1 day ( During evaluation visit)]
To compare the smartphone based evaluation of the Amsler Grid with ODYSIGHT (Amsler grid module) and standardized methods (paper Amsler Grid)
- Global functional disorders assessment with Odysight versus with OCT [1 day ( During evaluation visit)]
To compare functional disorder(s) detected or measured by ODYSIGHT application with anatomical data (OCT: Optical coherence tomography)
