Whenever visual or optometric services within the lawful scope

of practice of a duly licensed optometrist are included in any

program financed with public funds or administered by any public

agency, for aid to the indigent, the aged, the legally blind, or any

other group or class, the recipient of such aid or his parent or

guardian shall be entitled to choose whether such services are to be

responsible for such expenditures or services shall not, under any

circumstances, in informing a person requiring vision care, or for a

correction of any vision or muscular anomaly, either directly or

indirectly refer such person to any particular health discipline,

but shall merely advise such person the need exists for professional

services.
