Question
A newborn has appeared with unexplained red spots and is accompanied by vomiting. The question is asked about how long after mydriasis one can get glasses.
Answer
After mydriasis, the medication usually wears off after 6 hours, at which point a refraction test can be conducted to fit glasses. Doctors recommend having an eye examination before mydriasis and another one after, to ensure the accuracy of the glasses prescription. For the symptoms of the newborn, it is suggested to seek medical attention early to confirm the cause, as not all red spots and vomiting in newborns are due to vision problems.
