How long is a contact lens supplier required to keep records of prescriptions?

The requirement for record-keeping of contact lens prescriptions is guided by specific regulatory standards that prioritize patient safety and accurate dispensing. A contact lens supplier must maintain records for a minimum of five years. This duration ensures that there is an adequate historical record that can be referenced in case of any disputes, changes in patient vision, or to validate prescription renewals. Keeping records for this length of time also aids in compliance with both state and federal regulations, which are designed to protect consumer rights and ensure that optical health standards are upheld. This period reflects the typical time frame in which patients might return for follow-up exams or require refills, thus playing an essential role in ongoing patient care and medication management.
