A pair of spectacle progressive lenses configured for a wearer suffering from convergence insufficiency or imbalance. The lens of the pair which is dedicated to the dominant eye has inset values appropriate for matching convergence of the dominant eye, but the other lens of the pair, which is dedicated to the non-dominant eye, has inset values substantially equal to zero. Such lens pair helps in suppressing the non-dominant eye for intermediate and near vision tasks, therefore avoiding or limiting symptoms of convergence insufficiency.

Spectacles comprising a pair of progressive lenses

A method implemented by computer means for determining an optical function of an ophthalmic lens adapted to a wearer, the method comprising:

Method for determining an optical function of an ophthalmic lens adapted to a wearer

Method implemented by computer for determining an optical equipment including at least an optical lens and a spectacle frame, the lens being adapted to be mounted in the frame, the method including:

Method for determining an optical equipment

A process for manufacturing a negative ophthalmic lens having a central portion () and a peripheral portion () includes the steps of forming the central portion () by forming voxels of a first material having a first refractive index, the central portion having a peripheral zone at its periphery; and forming the peripheral portion () from this peripheral zone and contiguous to the perimeter of this peripheral zone, by forming voxels of at least one second material having a second refractive index, the second refractive index being strictly higher than the first refractive index.
