Looks matter, and so does visual comfort. Everyone likes to look their best,
including patients who choose to wear bifocals. The visible line across flat-top
bifocals, generally seen as an age marker, gives the lens an undesirable look.
At the same time it compromises visual comfort by creating a disturbing image
jump. Addressing these issues, Shamir has developed Shamir Duo, a new
generation of bifocal lenses that provides a more aesthetically appealing solution
improving the way the wearer looks, as well as the way they see.
A GOOD SOLUTION,
BUT NOT WITHOUT DRAWBACKS
Flat-top bifocals are a conventional solution for presbyopic needs, however they do include some troublesome disadvantages regarding both how the wearer looks and how they see. With their visible dividing line, flat-top bifocals give the wearer a look that is generally associated with advanced age, and furthermore, flat-top bifocals 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.
Traditional bifocal lens wearers have therefore had to compromise on their appearance as well as on the accompanying visual performance… until now.
A NEW VISUAL HARMONY
To overcome these disadvantages, Shamir has developed a new bifocal lens design – Shamir Duo.
An advanced Freeform lens, Shamir Duo offers surface continuity, eliminating the visible line.
It also offers optical continuity, eliminating the image jump and loss of image.
This enables Shamir Duo to maintain a natural, distortion free visual path as the eye moves from one vision zone to another.
Now with Shamir Duo, there is no need to compromise either on appearance or on visual comfort.
MORE ADVANTAGES THAN MEET THE EYE
In addition to improved appearance as well as improved vision, Shamir Duo offers other important advantages over flat-top bifocals which limit the type of lens materials and treatments that can be used, allowing less versatility and offering patients fewer choices. Now, bringing with it all the benefits of Freeform lenses, Shamir Duo lends itself to a variety of materials, tints and coatings. And as Shamir Duo represents a new generation of bifocal lenses, ECPs can enhance their differentiation and professionalism by offering a new generation of bifocal lenses at an attractive price.
