True or False: A seller can alter any aspects of the contact lens specifications.

The assertion that a seller can alter any aspects of the contact lens specifications is false. In California, as in many other jurisdictions, the specifications for contact lenses are determined by the prescriber, based on individual patient needs. These specifications include critical factors such as lens curvature, diameter, and prescription power, which are tailored to fit the unique anatomy and vision requirements of the patient.

Allowing a seller to arbitrarily change these specifications could lead to improper fitting and potentially harmful consequences for the patient's eye health. Such alterations should only be made if there is clear communication and approval from the prescriber, ensuring that any changes are medically appropriate and align with the patient's best interests. The integrity of the prescribed parameters is crucial for both effectiveness and safety in contact lens wear.

This understanding reinforces why the statement is valid; it underscores the importance of the prescriber’s role in determining appropriate lens specifications and the necessary safeguards in place to protect patient care.
