Q: How do patients get the autorefractor machine to show approx lower number eyesight? How to stop it?

A: The autorefractor machine measures the refractive error of the eye, which includes factors such as

nearsightedness, farsightedness, and astigmatism. It does not have the capability to "show" a lower number eyesight

on its own. The results are based on the actual refractive error of the eye at the time of the measurement. If a patient

is concerned about consistently receiving lower results from the autorefractor machine, it's important to discuss this

with an eye care professional. Factors such as fatigue, dry eyes, or focusing too hard during the test can potentially

affect the accuracy of the measurements. Additionally, changes in the eye's internal structure or health can also

impact the results. An eye care professional can provide guidance on how to ensure accurate measurements and

address any concerns about the testing process.
