  • Patent number: 10690939
    Abstract: 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.
