Eliminates lens segment separation line Shamir Duo is designed to address the limitations of traditional bifocal lenses - namely their negative aesthetic association with elderly people, and the jarring temporary loss of sight experienced when shifting one's eyes between their near and far vision zones. Duo overcomes the challenges of traditional bifocal lenses by effectively eliminating the highly visible upper and lower lens segment separation line, while continuing to ensure a smooth transition between near and far vision zones, without the "image jump" when switching the vision from far to near and vice versa. Who is it for? Aesthetics-conscious eyeglass wearers requiring near and far vision improvement, yet reluctant or otherwise unable to adapt to progressive lenses.
