Who is permitted to fit and adjust spectacle lenses or contact lenses?

The option that states a registered spectacle lens or contact lens dispenser is permitted to fit and adjust spectacle lenses or contact lenses is correct because California law specifically designates this role to individuals who are properly trained and registered in the practice of fitting these lenses. Registered dispensers undergo education and training that equips them with the necessary skills to ensure proper fit and adjustments, which are critical for a patient's visual health and comfort.

In contrast, while a high school diploma is a baseline educational requirement, it does not inherently provide the specialized knowledge or training necessary for lens fitting and adjustment. Health professionals such as medical doctors or nurses may have a robust understanding of overall health but typically do not possess specific training in optometry or lens fitting unless they specialize in that area. Optometrists, while qualified to fit and adjust lenses, represent a separate professional category with additional requirements and education beyond that of dispensers. Thus, the regulation emphasizes the importance of specialized training for those fitting and adjusting lenses to ensure compliance with best practices in patient care.
