Optometry: assistants and scope of practice.

Existing law prohibits any person, other than a physician and surgeon or optometrist, from measuring the powers or range of human vision or determining the accommodative and refractive status of the human eye or the scope of its functions in general or prescribing ophthalmic devices. Existing law provides that an assistant in any setting where optometry or ophthalmology is practiced who is acting under the direct responsibility and supervision of an ophthalmologist or optometrist may, among other things, perform tonometry and perform nonsubjective auto refraction in connection with subjective refraction procedures performed by an ophthalmologist or optometrist.
