Expert Tween™

For computer or task-specific visual needs, the Tween lens will keep your up-close work in the clear.

The Tween has a wider near vision region, and a soft design that eliminates swim effect and perceived lateral distortion. The lens promotes easy adaption and supports frame customization.

Tween delivers clear vision from reading distance up to 4 meters (13 ft.) and offers three clear distance vision options (4 ft; 7 ft; 13 ft.).

Tween comes with seven available degressions (+0.75 to +2.25), and two minimum fitting heights (14 & 18mm).

Note: The Tween’s distance area performs best with a minimum of 10mm of viewing area above the fitting cross.
