LENS DESIGN

 

SEED's unique "Dynamic Prism Ballast" design constitutes three designs, namely, the "Upper Portion Slab-off", Prism Ballast Design and "Adjustable Parametric Design".

What is “Dynamic Prism Ballast”?

“Dynamic Prism Ballast” is a design constituting three designs, namely, the “Upper Portion Slab-off”, Prism Ballast Design and “Adjustable Parametric Design.”

 

“Upper Portion Slab-off”

To maximize the effect of prism ballast together with the ease of fit, the upper portion of the lens is made thin and smooth according to the various parameters.

 

Prism Ballast Design

To allow the lower portion of the lens to have a suitable level of thickness, we adopted the prism ballast design.

 

“Adjustable Parametric Design”

To provide ease of fit for the wearers, the thickness of peripheral section of the lens is made thin according to the various parameters.

The edge of the base curve is also being lifted up.
