Co platí o krátkozrakém oku?
Správná odpověď je: B, C
U krátkozrakého oka dochází k protínání paprsků tvořících obraz v bodě ležícím mimo sítnici, konkrétně před sítnicí (blíže čočce). Dochází k nadměrné konvergenci světelných paprsků procházejících okem. Oko má příliš vysokou optickou mohutnost pro pozorování vzdálených předmětů, na něž nedokáže zaostřit. Krátkozrakost může být také způsobena nefyziologicky zvýšenou délkou oka. Ke korekci krátkozrakosti jsou využívány rozptylné čočky, které snižují optickou mohutnost optické soustavy oka.
