How we look matters to us all and we all want to look our best, especially those who wear bifocals. The visible line across flat top bifocals gives the lens an undesirable look. At the same time it compromises visual comfort by creating a disturbing image jump. Shamir has addressed this issue and developed Shamir Duo, which is now available to patients of Penzer Opticians. This new generation of bifocal lenses offers a more aesthetically appealing solution improving not only the way the wearer looks, but also the way they see.
So years flat top bifocals have been a good solution for presbyopic needs, but they do have some disadvantages. With their visible dividing line, flat top bifocals give the wearer a look that is generally associated with advanced age and they introduce a vertical surface discontinuity resulting in a disturbing image jump with loss of image as the eye moves from one visual zone to the other.
To overcome these disadvantages, this new Freeform lens offers surface continuity, eliminating the visible line. It also offers optical continuity, eliminating the image jump and loss of image. Therefore, this innovation enables the wearer to maintain a natural, distortion free visual path as the eye moves from one vision zone to another.
In addition to improved appearance and vision, these Freeform lenses offer other advantages that limit the type of lens materials and treatments that can be used, allowing less versatility and offering patients fewer choices.
