What's the difference between optician and ophthalmology?

Significant: An ophthalmologist is a fully trained md who has learned much of general medicine, and then has specialty training in medical and surgical diseases of the eyes. An optician is a technician who takes the eyeglass prescription of the ophthalmologist and the frame of choice of the customer, and makes proper eyeglasses.

Not a podiatry ?: Optician adjusts and makes glasses. Opthamology is a doctor who treats the eyes and associated diseases.

Education: Although all can be members of an "integrated eyecare team", the eyemd (ophthalmologist) is an md specializing in medical and surgical treatment of eye disease. The optometrist (not a medical doctor), has education and training to diagnose/treat some medical conditions of the eye but also prescribes optical lenses for refractive errors. The optician crafts and dispenses optical products.
