What must a patient be warned about when contact lenses are supplied from a seller outside California?

When contact lenses are supplied from a seller outside of California, it is crucial for the patient to be warned to consult with their optometrist if any eye problems occur. This recommendation is based on the important principle of ensuring proper eye health and safety.

The use of contact lenses carries certain risks, particularly if they are not fitted properly or if the patient has underlying eye conditions that may complicate their use. If a patient experiences discomfort, irritation, or any unusual symptoms while wearing their lenses, prompt consultation with an optometrist is essential for proper evaluation and management. This warning helps to mitigate potential complications and promotes patient awareness regarding their eye health.

While the other options may represent beneficial practices, they are not legally required warnings associated with the supply of contact lenses from out-of-state sellers. It’s essential to prioritize the patient's health concerns, reinforcing the significance of professional healthcare advice when dealing with any issues related to eye care.
