What role does an optician play in eye care?

An optician primarily focuses on filling prescriptions for corrective lenses and ensuring that the glasses or contact lenses fit properly and meet the specific needs of the patient. They work closely with prescription information provided by optometrists or ophthalmologists and are skilled in selecting the appropriate lenses, frames, and adjustments required for the individual.

The role of an optician does not include diagnosing eye diseases, prescribing medications, or conducting eye exams; these responsibilities are reserved for optometrists and ophthalmologists. Therefore, the correct answer helps clarify the distinction between the various professions in eye care and emphasizes the optician's specialized role in the process of vision correction through the dispensing of corrective lenses.
