Do you need a dilated eye exam for an eyeglass or contact lens prescription?
Answer:
A dilatedeye exam is not typically needed to get an accurate prescription during refractive testing. Farsighted (hyperopic) persons are the exceptionand may need dilation to obtain the most accurate prescription.
However, dilation is a part of a complete eye exam to examine the health of the back structures of the eye including the lens, retina and optic nerve. Evenif someone has perfect vision on an eye test, there may be eye problems that only a dilated exam would be able to uncover. You should follow your doctor's recommendation about the frequency of dilation during eye checkups.
