DIAGNOSTIC_TEST

bUDVA, bUIRA, bUNRA, bUICPS, bUNCPS

All participants will be assessed on the following clinical indexes: 1. Binocular uncorrected distant visual acuity (bUDVA) at four meters distance 2. Binocular uncorrected intermediate reading acuity (bUIRA) at 60 cm 3. Binocular uncorrected near reading acuity (bUNVA) at 40 cm 4. Binocular uncorrected intermediate Critical Print Size (bUICPS) at 60 cm 5. Binocular uncorrected near Critical Print Size (bUNCPS) at 40 cm All the above parameters are obtained using the Democritus Digital Acuity \& Reading Test (DDART).

DIAGNOSTIC_TEST

Contrast sensitivity

Contrast sensitivity is assessed with the Pelli-Robson test.
