An ophthalmic lens is presented in which the lens includes a progressive addition region and a dynamic optic. The dynamic optic and the progressive addition region are in optical communication. The progressive addition region has an add power which Is less than a user's neat viewing distance add power. The dynamic optic, when activated, provides the additional needed optical power for the wearer to see clearly at a near distance. This combination leads to the unexpected result that not only does the wearer have the ability to see clearly at intermediate and near distances, but the level of unwanted astigmatism, distortion, and vision compromise are reduced significantly.
Verre ophtalmique comportant une région d'addition progressive et un élément optique dynamique. L'élément optique dynamique et la région d'addition progressive sont en communication optique. La région d'addition progressive possède une puissance additionnelle inférieure à la puissance additionnelle de distance de vision nette d'un utilisateur. Une fois activé, l'élément optique dynamique fournit la puissance optique supplémentaire nécessaire permettant à l'utilisateur de distinguer clairement de près. Cette association produit un résultat surprenant dans la mesure où elle permet à l'utilisateur de distinguer clairement de près et à des distances moyennes, mais aussi de réduire sensiblement les niveaux indésirables d'astigmatisme, de distorsion et de compromis visuel.
