Salut, 

Pour le QCM 3

Déjà on sait que la personne est myope donc tu peux éliminer la b et d car elles sont > 0 ensuite, 

on sait que PR correspond à F' donc pour trouver Vcorr on fait 1/OF' avec OF' = PR = - 5, du coup tu trouves 1/-5 = - 0,2 dioptrie 

 

Et pour la 4 je t'avoue que je sais pas 🙄
