Embodiment Construction
[0049]A first aspect of the present invention relates to a method for comparing a first and a second optical lens by an automatic refractometer head controlled by a control module. A second aspect of the invention relates to a module for controlling an automatic refractometer head to implement the method for comparing first and second optical lenses according to the first aspect of the invention. A third aspect of the invention relates to a system for implementing the method according to the first aspect of the invention, the system comprising a control module according to the second aspect of the invention and a selection screen.
[0050] definition
[0051] Within the scope of the present invention, "optical lens" is taken to mean an optical element of a quality suitable for the production of prescription spectacles, without prejudice to the material of its manufacture, which may in particular be glass or plastic. The term "ophthalmic lens" or "corrective lens" may also be ...

The invention relates to a method for comparing first and second optical lenses as well as to an associated control module and an associated system such that: when the control module receives a selection suggesting the first optical lens for the first time, a suggestion for the second optical lens can be selected on a selection screen and no validation symbol can be selected on the selection screen; when the control module receives the selection of the suggested second optical lens, the suggested first optical lens can be selected on the selection screen and first and second validation symbolscan be selected on the selection screen, the first symbol indicating that the first and second optical lenses are identical, and the second symbol indicating that the second optical lens is better than the first optical lens; when the control module receives the selection of the suggested first optical lens for the second time or more, the suggested second optical lens can be selected on the selection screen and the first symbol and a third symbol can be selected on the selection screen, the third symbol indicating that the first optical lens is better than the second optical lens.
Description
technical field [0001] The field of the invention is that of performing vision examinations on subjects that make it possible to determine whether and what corrections are required for said subjects. [0002] The invention more particularly relates to a method for comparing optical lenses by means of an automatic refractometer head controlled by a control module, for example during a vision examination or during a simple verification of a worn vision correction. The invention also relates to a module for controlling an automatic refractometer head for implementing a method for comparing optical lenses and a system comprising said control module and a selection screen for implementing the method for comparing optical lenses. Background technique [0003] Examination of the subject's vision begins with objective refraction measurements and continues through subjective refraction measurements. [0004] Objective diopter measurements are usually performed by the operator with t...
