It’s essential to keep in mind that vision screenings take a very basic look at your eyesight and
are not used to diagnose or treat vision problems. They are designed to merely detect them and are
often performed by a school nurse or pediatrician. While a vision screening may be useful in
identifying a vision impairment that requires further care, it is by no means a substitute for a
comprehensive eye exam. As a rule, the only way to precisely detect and diagnose any vision
abnormalities or identify the presence of eye disease is through a comprehensive and in-person eye
exam.
