Claim 5:
6. A module for controlling an automatic refractor head for the implementation of a method for comparing first and second optical lenses successively arranged in a slot of the automatic refractor head corresponding to a same eye of a user according to claim 1, the control module being configured to:
display simultaneously on a selection screen a proposal for a first optical lens, a proposal for a second optical lens and all or part of a plurality of validation symbols each indicating a possible result of a comparison between the first and second optical lenses;
receive a selection of the proposal for the first or the second optical lens or a validation symbol;
on reception of the selection of the proposal for the first or the second optical lens, arrange said first or second optical lens in a slot of the automatic refractor head;
the display on the selection screen and the reception of the selection being such that:
when the control module receives the selection of the proposal for the first optical lens for the first time, the proposal for the second optical lens is selectable on the selection screen and no validation symbol is selectable on the selection screen;
when the control module receives the selection of the proposal for the second optical lens, the proposal for the first optical lens is selectable on the selection screen and first and second validation symbols are selectable on the selection screen, the first symbol indicating that the first and second optical lenses are provide equivalent vision correction to the eye of the user and the second symbol indicating that the second optical lens provides better vision correction to the eye of the user than the first optical lens;
when the control module receives the selection of the proposal for the first optical lens for the second time or more, the proposal for the second lens is selectable on the selection screen and the first symbol and a third symbol are selectable on the selection screen, the third symbol indicating that the first optical lens provides better vision correction to the eye of the user than the second optical lens.
