Fatima Tabatabaei, the daughter-in-law of Imam Khomeini, recalls that once Imam suffered an eye problem and consulted a doctor during stay in the holy city of Najaf. The doctor suggested Imam to quit reading Quran for some days.
Imam replied while laughing “I need eyes for reciting Quran, what is usage of eyes if I couldn’t read the scripture. Please find some way so I can keep reading the holy book”
