What is true about a contact lens prescription?

A contact lens prescription is specific and can indeed be transferred from one prescriber or fitter to another, which highlights the correct choice. This facilitates continuity of care, allowing patients to obtain their contact lenses from various locations or providers without needing to have a new fitting or prescription every time. It is essential that these prescriptions meet all regulatory and professional standards, ensuring they provide the necessary information for safe and effective contact lens wear.

The other options do not accurately reflect the nature of contact lens prescriptions. For instance, interpreting the prescription over the phone is not a requirement and could lead to miscommunications. Additionally, contact lens prescriptions have defined expiration periods based on state or local laws, commonly ranging from one to two years rather than a blanket term of 10 years. Finally, a contact lens prescription differs from an eyeglass prescription due to the need for measurements specific to how the lens sits on the eye, thus distinguishing the two types of prescriptions in terms of fitting and measurements.
