i know there has been a few posts on children's optical prescriptions, and asking for explanations, so here is another one
My DD2 is 3 and has a prescription of +3.5 Sph in both eyes I didnt really get time to ask the optician, as although he was lovely, DD announced she needed a wee just as he finished the exam, and by the time she had finished, he had moved on to his next patient.
He did mention something about a slight turn in her right eye, which wouldnt surprise me as DD1 had the same and required patching for a few years.
On our way out, the elder optician, who saw DD1 a few months ago, glanced at DD2's prescription, smiled and said, "oh, its about half as bad as DD1's!" I knew DD1 had poor eyesight, but that was still a bit to hear!
