A2 Low Addition Molds

A2 Crown

2013-04-20T20:01:23+00:00

12mm Corridor Progressive New Design

A2 Vision Technologies provide new generation of progressive short corridor design - super-short corridor 12mm "Crown". The fitting cross is 2mm above the optical center and the recommended fitting height is 15mm.

Benefits of the design:

New cutting method of ceramic block provides the high precision of the mold.
Following the tradition of A2 Vision design, the distance zone is clear and wide.
The peripheral aberration moved inside of the functional areas of the lens.
The new aspherical solution maximizes the width of the corridor area, unlike conventional
short corridor progressive design.
Gradual translate of the central line from the corridor to the reading zone leads to the wide
clear reading zone - the best solution for the super-short frames.
The design gets full addition power in the 12mm corridor length.

A2 Kids

2013-04-20T20:00:07+00:00

10mm Corridor Progressive Lens Design

A2 Kids is an extremely short corridor progressive lens design, especially developed to slow the unique genetic myopia common among children throughout Southeast Asia. Allowing quick adjustment, A2 Kids reduces the effort required by the eye muscle to focus on up-close vision. A wide reading zone enables a child to read a full page at a glance.

A2 Kids is specifically designed for small children's frame, with lower and fewer peripheral cylinders than in traditional progressive designs. With less peripheral blur and a very soft design, A2 Kids is the ultimate solution for a child's active lifestyle.
