Dave and I were out to dinner tonight and saw a little girl, probably around 2 years old, who was wearing glasses. We wondered how does the doctor get the correct prescription if she cannot answer he questions an eye doctor would normally ask?
So today if you know, go ahead and answer this question. Or ask another burning, pondering question you've always wondered about.

Haha. Actually sometimes little kids are REALLYY cross-eyed, so glasses are supposed to help correct that. But yeah, 2 years old is pretty young to have such a responsibility!
I imagine they try to modify the questions, and probably have some different assessment tools. With the advanced technology, they may be able to figure it out with less input from the patient . . . .
i had glasses from the time I was 1 until I was old enough for corrective surgery at 8. the question the eye doc ask you are NOT the critical part of determining a prescription. the varying strength of testing lens helps the doctor look at your eyes as they strain and the questions help the doctor tweak the prescription to your comfort. besides, the majority of the time they ask you these questions, you are confirming their assumptions on your vision.
if determining prescriptions was subjective, eye doctors would be out of business.
95% - 99% of a prescription is determined by using a retinoscope or slit lamp, not the Q&A.
