state one advantage of using a plane mirror in optical testing .
ermmm, you have either misstyped the url, and hoped for newbielink:http://www.thenakedhomework.com [nonactive] or you just need to try and disguise you questions so they dont look like you want your homework done.
During woodwork class at school about hurumph years ago, the teacher (affectionately known as Wally Woodworm) asked me to go the other woodwork classroom and ask the teacher there for a Viscount plane. I fell for it! Off I troted and made myself look a complete twit.Vickers Viscount c.1960

A third advantage is that the eye test chart has to be a mirror image so it's less likely that people will "remember" what it says rather than read it.
I think the question was referring to 'eye testing'.There are two advantages in using a mirror (plane, usually).Firstly, the operator can change the chart and play with the prescription in the test glasses in the same place (the chart can be placed just behind the person being tested).Secondly, the room only needs to be half the length of the full distance needed for viewing the test chart because the image depth is the same as the object distance.
