A2 Kids
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.
