The third consideration, on which the Minister touched, is whether we will have best practice. It appears the Minister has determined that the legislation is aimed at best practice in this area. I welcome the thinking behind the Bill and the Minister's willingness to consider amendments because it is not in the interests of optometrists to become involved in treatment other than of the sort referred to. I welcome the legislation, which will, after almost 50 years, ensure customers of optometrists will benefit.
