Opticians are individuals who are trained to design, verify, and fit eyeglass lenses and frames, contact lenses, and other devices to correct eyesight.

Opticians are not trained to diagnose or treat eye diseases, but when they do suspect a medical eye problem they should refer the patient to an ophthalmologist.

An optician makes optical aids-fits, adjusts and dispenses glasses, contact lenses and other optical devices on written prescriptions of a licensed ophthalmologist or optometrist
