Which role performs laboratory work in lenses, including finishing processes?

• A. Opticians
• B. Ophthalmic technicians
• C. Ophthalmic assistants
• D. Ophthalmic laboratory technicians

Answer: (D)

The key idea is that turning prescription data into finished lenses happens in a lens fabrication setting. Ophthalmic laboratory technicians specialize in this work. They handle lens blanks, choose the appropriate material, and operate the equipment used for grinding, polishing, edging, and finishing lenses. They also perform coating application, drilling mounting holes when needed, and quality checks to ensure the final lens matches the prescription and fits correctly in the chosen frames. This role is all about producing the actual lens product.

Dispensing roles, like those who work with frames and advise patients, focus on choosing frames, measuring interpupillary distance, and fitting the lenses into frames, not fabricating or finishing the lenses. Ophthalmic technicians and assistants support clinical activities and patient testing, rather than performing the lens finishing processes.
