What three methods must nonresident contact lens sellers provide for prescription verification?

Nonresident contact lens sellers are required to provide multiple methods for prescription verification to facilitate easy and efficient communication with both the prescribers and consumers. The correct set of methods includes a toll-free phone number, fax number, and email address.

The provision of a toll-free phone number ensures that prescribers can reach out without incurring long-distance charges, making the process more accessible and likely to be used. This can be crucial for ensuring rapid communication, especially when timely verification of prescriptions is needed.

The inclusion of a fax number is also essential, as many healthcare providers still rely on fax machines for transmitting sensitive information securely. This method allows for the swift and safe relay of prescriptions and other vital documents.

Lastly, an email address is important for digital communication, which is becoming increasingly common. It provides a written record of communications, which can be beneficial for both the seller and the prescriber in case of disputes or clarifications needed.

Together, these three methods align with the regulations that aim to protect consumer safety and enhance the verification process in the distribution of contact lenses.
