Refractions are one part of a complete eye exam. Starting with an eye chart and using various types of lenses the doctor will “measure” your visual accuracy. These results determine what your eyeglass prescription should be.
When billing, some insurances require the refraction part of your exam to be separated from the medical part of your exam. Medicare, designed to help cover the cost of "medical" care, does not contribute to "wellness" care, such as hearing aids and dental care. Medicare, Medicare supplements, and some other insurances do not pay for the refraction. You are responsible for the refraction fee.
