What is a professional who makes and adjusts optical aids from refraction prescriptions called?

An individual who makes and adjusts optical aids, such as glasses and contact lenses, based on refraction prescriptions is referred to as an optician. This professional is specialized in interpreting prescriptions provided by optometrists or ophthalmologists and is skilled in fitting, adjusting, and dispensing eyewear to meet patients' visual needs. Opticians also play a crucial role in ensuring that lenses are properly crafted and fitted to provide optimal vision correction.

In contrast, an ocularist typically focuses on the fabrication and fitting of ocular prostheses for patients who have lost an eye. While optometrists are primary eye care providers who perform eye examinations and prescribe corrective lenses, they do not usually create or adjust the optical aids themselves. Ophthalmologists are medical doctors who specialize in eye health, including the diagnosis and treatment of eye diseases, performing surgeries, and prescribing corrective lenses, but like optometrists, they do not engage in the making or adjusting of optical aids directly. Thus, the definition and role of an optician align perfectly with the question regarding the professional who directly handles the craft of optical aids from prescriptions.
