My ds had an eye test as he was occasionally complaining of a sore eye. Turns out he has a intermittent 'lazy ' eye esp when tired. Optician used eye drops to accurately measure vision etc and they stung like crazy and he had very dilated pupils for rest if day. Several months later we have hosp referral come for further test and itmentions they'll need to use eye drops again. I sm happy for him to be seen but don't really want him to go through the painful exp of dilating drops again when its already been dobe. Can they examine him without?
