Abstract: 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 near 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.

Abstract: The present invention illustrates various methods of attaching a pair of eyeglass lenses or a lens shield to an eyeglass frame using magnets or magnetically attractive material. The magnetic attachment methods are beneficial because they allow the user to have interchangeable lenses or shields for indoor and outdoor use, enhancing their visual acuity during work or play. The lenses may be tinted, prescription, protective eyewear, or plano. The magnetic lenses are convenient and user friendly, allowing intuitive, tool-less interchangeability with no need to twist or stress the frame. These methods of attachment require no specific instructions or tools when the user replaces lenses.
