optician

An optician is an eye care specialist who makes, fits, and sells optical devices, such as eyeglasses and contact lenses, based on prescriptions from optometrists or ophthalmologists. While an optometrist measures and assesses vision, determines the need for corrective lenses, and may prescribe medication, an ophthalmologist is a physician who diagnoses and treats eye diseases and can perform surgery. Opticians focus on the technical aspect of providing the prescribed vision correction. In the UK, the term "ophthalmic optician" is used for someone who examines eyes and determines the need for eyeglasses or medical treatment.123
