1. A method for comparing first and second optical lenses by an automatic refractor head controlled by a control module, the first and second optical lenses being successively arranged in a slot of the automatic refractor head corresponding to a same eye of a user, the method being implemented by the control module and comprising:
displaying on a selection screen a proposal for a first optical lens and a proposal for a second optical lens;
receiving a selection of the proposal for the first optical lens;
arranging the first optical lens in the slot of the automatic refractor head on reception of the selection of the proposal for the first optical lens;
receiving a selection of the proposal for the second optical lens;
arranging the second optical lens in the slot of the automatic refractor head on reception of the selection of the proposal for the second optical lens;
displaying on the selection screen a plurality of validation symbols each indicating a possible result of the comparison;
the method 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 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 optical 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.
